  1. Hello, 2016 ktm 150sx. I am the only owner and have less than 20hr on this bike. It developed a shifting problem. It will not stay in gear, jumps around in and out of all the gears, running or not. I pulled it out of the shop yesterday pushed it up to the another building leaned it aganst the wall. came back to move it and it was in gear. The shifter feels real simmilar to a small kids quad. where all the gear shifts are one direction, and even though you shift down to first gear you can still just keep clicing it down all day long (if you follow what I mean by that. it does not hit a floor once you are in 1st like any other 1 down 5 up tranny). I have found and downloaded the manual. I could find the link if anyone needs it, but nice guy 10 dollar donation and instant access to 100's of ktm service manuals. Anyways i found the time to start tearing it down, but thought it would be best to see if anyone has had or seen a similar issue be for I start.
  2. Hi all, I have a 2004 kx 250 2 stroke and it wont start. it only backfires. I was out riding it one day and came up to a stop so the bike was just idling and it started to try and die so i revved it up a few times then let it die and now it wont start back up. It only pops or backfires when you kick it. Its getting good spark and i just put a brand new plug and coil in it. I took the reeds apart and they look like they're brand new. It was running great before so i dont know what happened. Im thinking it could be a fuel problem even tho the plug is a little wet if you take it out after a bunch of kicking. Any help would be greatly appreciated Thanks
  3. Hello Thumpertalk Community, My First Post here and i'm going to start with a Big one... for me at least. On my 2005 XR650r wich is an ED Type i guess? (Bought in Germany i think(2nd Owner)) My Stock Stator somehow broke after long investigations a specialized company found out that one of the Coils wich is responsible for the Ignition is broken. Repairing would've cost me about 300€ (~280$ i guess?) and a compleatly new OEM would've cost me 600€ wich is why i bought a RickyStator from Xr'sOnly after a good month the stator arrived (due to customs) and as i Wanted to Replace the old one i noticed a big problem: The OEM Stator has wiring wich looks like this: A multi caple Plug with 5 Cables in it. 2 Cables for the ignition. The RickyStator one Looks like this: 8-10 Loose Cables of wich 2 where in a MultiCable Plug Ignition Cables are Known Dosn't fit but i got a question Would the Bike run if i only run the Ignition Cables? Does every cable have to do 1 exact "job" or are the rest of those wich arn't igniton cables only for supplying the rest of the bike with the 12 Volts? Anyone had the same or similar Problem? Pliz halp am only good with mechanical problems not with electrical stuff Thank you in Advance i guess 🙂
  4. Today I decided to clean the carburator of my crf250r 2005. It was my second time doing it. When I opened up the top of the carburator to remove the slide, I didn't remove the throttle shaft screw and I still slid the slide out, but the control arm is now stuck. This video explain what I should have done at about 1:00. The only difference is I didn't remove the throttle shaft screw and now the control arm is sutck up and I can't slide it back down with the slide. I was still able to remove the slide. Anyone knows how to fix this? I can't acces the throttle shaft screw anymore since the control arm is stuck up.
  5. I would like to preface this by saying that this might be somewhat of a rookie question, but never the less I am in search of answers. For some time now I have noticed that the front brake on my 2003 450 EXC has been fairly squeaky when coming to stops, even though I have hardly put any miles on the bike since I installed new pads several months ago. Upon closer inspection to the front caliper I noticed that the outside stationary brake pad does not appear to clear the thin channel located at the top of the brake pad for the rotor to pass through (picture provided). I would also like to add that I have an extra front caliper for my model KTM that also appears to have the same "issue", and this caliper is also the one I will be posting photos of, instead of the one currently mounted on the bike. So, is it possible that this is the source of the banshee screech my front brake seems to emit whilst coming to a stop? If so, does anyone know of any fixes for this issue, or is it something that I just shouldn't be worrying about? As a final side note, the only direct, let's call it, "performance" issue I have noticed is that my front brake is unable to keep the front wheel locked whenever I attempt to do burnouts. I could basically be squeezing the lever so hard that I feel like it's going to snap off in my hand, and the front wheel will either slowly roll, or sightly hop. Thanks to all in advance for any help or wisdom given, it is very much appreciated.
  6. Got a 2005 DR-Z400S with only 2500miles on it a couple of days ago. It's in really good condition appearance wise and runs fine for the most part, has supposedly been sitting barely used for a few years. Will run fine for several miles at a time, but will suddenly begin surging and stuttering, as if throttle is cutting out momentarily, then if I release the throttle the engine usually just dies and refuses to start up without dying again within a few seconds. If it's sitting idle at the time the problem occurs, I can hear the engine begin to drop revs and sound less consistent, then it usually dies after about 10 seconds even if I try to keep the revs high. While this is going on the throttle also feels less responsive. If I then just wait at the side of the road for about 5 minutes, it'll usually then start right up first time and I'll be on my way for another couple of miles until it happens again. The distance I've managed between compulsory stops has varied between about one mile and ten miles. It's happened when the bike's idle and when I've been doing 70mph on the motorway, which was great fun. Any thoughts on what the culprit could be? Thanks a lot
  7. Just bought a 2000 KX 250 two-stroke for a great deal when looking for a project bike. When I put the bike in neutral which is a little hard to find, it jumps into first gear by itself and trys to takeoff no matter if I squeeze the clutch lever or not. When I first started the bike it basically did a burnout in my garage with no throttle applied and the clutch lever pressed then it just stalls out eventually this happened for about five seconds. Attached are some pictures of my clutch disk and clutch basket from what I researched today the basket should not look this bad , but do you guys think? Is the clutch the source of my problems or is it something internal and would I need to split the case.
  8. Hi everybody. I come to this forum which I've been browsing extensively. Despite the large amount of information concerning the settings of this carburetor on thumpertalk, I have a problem that I can't solve. That's why I'm creating a new topic despite the amount of information I already have. I live in the swiss alps and I bought a 2004 european WRF450 supermoto six months ago. Perfect bike for the small winding roads near my house. I have completely revised it and it works well. Here are the different characteristics: -Main jet: 165 defined by the method of stopping carburation at full throttle. good spark plug color. -Pilot Jet: 50 -Pilot air jet: 80 -Pilot screw: 3 and 1/2 turn out!!!! -Needle model/Clip position: OBDUQ/ 2nd positon from the top (european stock) (OBDUR ordered for lower clip height) -Exhaust: Stock -AP timing set correctly with a 3.1mm diameter shaft. -Altitude where you ride: 1500-2000 -Valve lash good The bike starts well at the first kick. No bugs when the motorcycle is running As you can see the pilot screw is (much) too loose. Even if I increase the diameter of the pilot jet (to have a richer setting and to be able to tighten the screw in a correct range),the setting of pilot screw remains the same: 3 or more turns out. I went up .48 to a .55 pilot jet and the problem remains the same. The carburettor has been completely disassembled, ultrasonic cleaned, all gaskets changed. the height of the float has been adjusted to 8 mm. Pilot screw, o-ring and spring are new and have been ordered from Yamaha. I don't understand why the change of pilot jet has no effect. Ideas?
  9. i’m tryna raise my sag a bit except the the plastic nut that ktm/husky have is just getting dented by the screw driver. i know there’s tools out there designed for it but the ones for dirt bikes are just another punch so i figure they would strip/dent the plastic aswell. otherwise there’s those ones that are actually like a spanner except they’re only really useable when there’s open space around the nut. Am i doing something wrong? has the plastic gone soft over time? what are your guys thoughts?
  10. Hey guys I just bought a 1979 ts 125 the other pulled it apart and threw it together...well most of it anyways... my problem is getting the clutch cover back on due to how the clutch is setup. With a sort of rack and pinion setup going on? Hoping for pointers I haven't ever built an older bike like this before! Thanks all
  11. I got a question. I own a 2016 KX 85. It ran AMAZING after it first bought it used and was in beautiful condition and I picked it up for only 2500. I was riding when all of a sudden it started bogging down right before the power band.i don’t think it’s jetting because the bogging just turned on like a switch and it was running perfect before it. The bike was like that for a month. Apparently the previous owner never oiled the filter so it was dry as a rock and was falling apart and got sucked into to the intake so I’m guessing my power valve is gummed up or stuck close or open. I was riding one day with the bog issue and about 35 minutes of riding I shut it off to take a break. Came back 20 minutes later and it would not start.I changed the spark plug, cleaned out the carb,checked the reeds,and tried hill starting it but nothing. When ever I try to hill start it I can hear it trying to crank and It starts for like half a second but then dies.I don’t remember if I left the fuel petcock on but what I’m guessing is that I flooded the engine and tried starting which messed up my electronics.The reason why I think I flooded the Engine is because when I took off the reeds the intake manifold and reed were soaked in gas.I heard that starting the engine while flooded can mess with a woodruff key or your CDI or something. There is spark coming from the plug though.And yes I mix the gas with oil at 32:1 cause I’m in the pipe all the time.This is my first time owning a 2 stroke.Any answers or tips.
  12. Hello everyone. So this is a bike I bought recently, it’s a 2011 KX250F, first of their fuel injected models, it is single port injection. Everything about the bike is fine, start easy, runs amazing, plenty of compression, recently reshimmed valves and fully serviced. But there is one issue with the bike when you’re on it hard, it seems to have a limiting problem. I’ve taken a video and uploaded it onto YouTube, the link is here; In order of sequence, the first rev on limiter is neutral about 4/5ths on the throttle and it limits the way it should. The second is full throttle in neutral, it kind of hesitates and splutters. The third is in gear which clutch pulled in full throttle, limits too slowly, almost like it’s starved of fuel. The 4th is in gear, clutch out, full throttle, limits sporadically, again, like it’s starved of fuel or misfiring. The bike doesn’t seem to limit properly in gear with 4/5ths throttle like it does in neutral either. anyone have any ideas on what this could be?? It has me stumped. Cheers!!!
  13. My output shaft on my 2007 klx110 was broken so I split the cases replaced the shaft and put the cases back together. Every turned smoothly, until I tightened the crank case bolts. When I tightened the crank case bolts, the crankshaft became hard to turn. The more I tightened the bolts the harder it was to turn the crankshaft. I can’t seem to figure it out and I think I have literally split the cases 15 times by now! Any possible solutions would be much appreciated, Thanks!😶🤔
  14. Hi i had a problem with my husqvarna fe 250 2015. I have been riding it for a year and suddenly it wouldnt start. Not even crank. I cleaned all the contacts and checked the fuses. In the process i accidently connected my battery backwards, a mistake i will never do again.. But after going through all contacts and changing the main fuse it suddenly started, ran for a few seconds, ran poorly and then the rectifier started smoking. Bought a new one but all i get is cranking. No sound from the fuel pump, no spark. All the relays and fuses seem ok. Cleaned ground surfaces, tried a new battery. I measured the ignition coil and got the right amount of ohm. Does anyone know if the Ecu could be damaged? Also wondering if the stator/pickup could be damaged?
  15. I recently picked up a 2004 cr85 with a fresh top end, v force reed petals, new crankshaft, and full gasket kit. I just installed a new air filter aswell. The bike seems to be in good running condition except for the fact that when it idles it will idle very high, but rarely it will idle normally by itself but usually i will have to let out the clutch slowly untill it almost dies then pull it back in quick then it will idle fine untill i hit the throttle again. Anybody know what the issue is??? Thanks
  16. Yesturday my bike started stuttering, just a little over closed throttle (on low rpms), on high rpms, it is ok... Sounds exactly like water in the gasoline... No error codes... 2 hours after sitting there cooling, I went to start it... oh nooooo.... after 30 minutes of kick starting and sweating, I managed to turn it on while someone on another motorcycle pushed me... it just needed faster cranking... So I finaly got home, and started looking for the problem... I emptied the gas tank, (although there was no water)... I put new gas Fuel pump checked... Fuel injector checjed... Coil checked... Pick up coil checked... pulses fine Checked all cables, no short circuits... So... when cranked I initially had spark, but no fuel... afterwards, no spark-no fuel... No error codes.... Any opinions?
  17. My engine on my 2017 Husqvarna fc 250 rattles when the clutch is not pulled in. I’m not sure if this is normal as it is my first 4 stroke but I assume it is not. Any help or knowledge about this will help alot
  18. Hey everyone! So I’m stuck in a bit of a dilemma and could really use all your help as I’m kinda new to dirt bikes. So a few weeks ago I ran the bike too hard without letting it warm up properly and as a result, the piston over-expanded and got damaged. I educated myself and I finally finished rebuilding the engine and made sure everything’s to spec before putting it back together. Here’s where the problems start... The bike wouldn’t start with the new piston. There is a nice blue spark and the spark plug was getting wet but barely. Slapped a new plug in there after putting a few drops of pre-mixed gas into the spark plug hole and it finally started in 1 kick. I hear cycled it perfectly and it ran very well. All things were going well...until I got to the 3rd gear. As soon as I switched into 3rd the engine bogged and died. At this point I kicked and kicked and it wouldn’t start. It also feels like it lost compression because of this, but after a few slow cranks the compression comes back. How would that even happen?! I’m really stumped on this because I’ve done everything to spec and heat cycled it properly on a new top end so I really don’t know what could be wrong. Any help will help immensely. Thanks everyone!
  19. Let me start off by saying, i just got into riding about 6 months ago so i could use some advice. I bought a DRZ400E and wanted to make it street legal so i got a Tusk legal kit. When i went to install it i realized i was in way over my head so about half way through routing the Tusk wiring harness i decided i would do it another day because i didn't realize how much time it would take. So i took everything off and put all of the original wiring where it belongs. I was afraid i messed something up so i went to electric start the bike (make sure it works still). It did turn over but i didn't realize the bare headlight wires were just hanging there, and they touched and created a spark. Since then nothing electrical works on the bike. I put the battery on a charger and it is fully charged but nothing works. I looked everywhere for frayed or burned wires but i couldn't find any, everything looks okay but nothing works. Should i just order an OEM wiring harness or is there something I'm missing?
  20. Pulling into work today my bike stopped being able to downshift. I tried to downshift from third to second and the shifter didn't come back up (it stuck down) so I tried up shifting instead and it worked. It shifted flawlessly all the way up into 5th, but now won't downshift. Things that might help speed the conversation along... - The bike is running fine otherwise and not making any strange noises. - Rolling forward and back doesn't change anything - Pushing in and out on the lever while trying to downshift does nothing. - The lever swings down freely, all the way to the frame, and is returning to its rest position. There is just not the usual click of the gears changing. Anyone have any ideas? Thanks in advance.
  21. hey so i encountered a problem so i drained all the coolant, and checked the valves on the bike and it was all in clearance, put it all together filled up the coolant, fired up, let it sit in the garage for a bit noticed coolant leaked out the over flow and i went ahead and topped it off and let it sit for a while and i just looked at it there was what looked like probably most of the coolant that was in the bike on the floor anyone have any idea what i should do next? the store is closed so i can't buy anymore coolant atm i use engine ice.
  22. dropped the bike doing a dirt donut, Pretty sure I broke a pin on the change drum /gear holder star thing (and 1 week from my Friday the 13th DMV test that I need this bike for) but found a pin in the oil pan when I was trying removing the gear changer face plate. couldn't remove the plate because I realized you need to get the chain and sprocket out of the way since I don't have tools for either of those things I was wondering if I could get away with EITHER removing the sprocket OR the chain ...to save money. if not I guess ill just have to buy $400 impact wrench + a $200 master link revet tool.
  23. I have a 2018 Fe 501 with only about 60 Miles on it. I noticed today that at idle, if I blip the throttle quickly and then let off the engine will either bog down or die completely. I thought it may be related to the JD tuner I had just installed last night, but I unplugged the tuner and it is still doing it. Has anyone else had this issue? Please help!
  24. Hey guys, I went to see this 625 SXC LC4 whis is sold in a good price but the condition is not that good. I recorded the engine sound so that possibly experienced owners can recognize any engine problems such as camshaft bearing failure etc. I appreciate any input...
  25. I recently replaced water pump and seal after I noticed that my '02 CRF450R was spilling coolant on easy trail rides. After the water pump swap (which was successful), I noticed the same problem. It's interesting - the bike only spits coolant (I mean a LOT of coolant) after passing anything above 1/2 throttle. The bike makes this weird 'gurgling' noise, like trying to suck through a straw when your glass is almost empty. This is weird because I properly bled/ burped the radiators with coolant, and filled them to normal operating levels. The coolant spills through overflow hose. anyways - I swapped the radiator because I thought maybe the bike was running hot. I purchased oversized radiators, bought a 1.6 radiator cap (with a temp gauge) and bought engine ice. The bike runs very very cool - the temp gauge allows me to see this. Still, the bike shoots coolant out of the overflow after going above half throttle, making the same weird gurgling noise when it does. Bike has all of its power, top end was replaced not too long ago. I'm lost and don't know what is wrong with the cooling system in my bike. How do I make the bike stop shooting out coolant, and stop making the weird gurgle noise??? Any advice would help me!!! Thank you!👍
