  1. Was riding my 450, testing out a new speedometer, shifted into 2nd, moved a couple feet and heard a loud crack noise from engine area. Will not turn over, sounds like its jammed or seized from moving. My guess is tat the timing chain just exploded and fouled everything up. Haven't found time to open it up. Thought I'd go to forums to get some opinions on what to look at first. As far as back round info: Engine was opened up to replace some gaskets. replaced my valves and adjusted rockers to .05mm. Timing chain taken apart a couple times. Shifts through gears fine even though it doesn't run. I am not very fond of ktms or dirt bikes in general but fairly mechanically inclined. I don't know what to do so here I am on the forums. Any help or advice is much appreciated. Thank you.
  2. I have a 2008 ktm exc 450 and recently replaced the head gaskets and now Im checking the valves. After rebuilding everything up to this point, id been able to get the camshaft with timing chain to slide into place just fine. But after removing one of the rocker arms to put a valve shim in, the cam will no longer slide all the way in. It stops with about 1/4 inch left and it feels like theres a fluid pressure preventing it from goin the rest of the way. I can force it if I try hard just enough to get the plate on the gear portion, but its not enough to screw tight. Did I mess something up? How do I get it to slide in like i did before?

    07 450 kickstarter stuck

    Ok so here's the thing, replaced top end and bike ran perfect then at the end of the day for some reason the kickstarter started getting stuck, it gets stuck on the compression stroke but if you put steady weight on the kicker it'll slowly start going down and then it'll kick fine until it gets back on the compression stroke again. Also if i take the spark plug out it'll kick perfectly fine. Any ideas i cant seem to figure it out. Thanks
  4. I just purchased a new 2017 KTM 450XC-F and really love the thing. I rode a buddy's 450 and knew it was the bike I was looking for. My 250 just wasn't doing it for me in the power department and I'm not fond of revving the bike to get what I need out of it. It starts fine, but it takes a couple of seconds for it to start up. Not a big deal for most, but I need it to start much quicker to be competitive for harescrambles. Looking up the battery, it doesn't tell me anything about turning amperage or anything of that sort. Curious to know if anyone has replaced the stock lithium battery to get something to be competitive off the line and what they found to be useful. Secondly, I really love the clutch on the bike. It's silky smooth, but once in a while the bike just flames out and it drives me nuts. I don't want to get a Rekluse, but I can't have it flaming out on me every 30min or so. Has anyone had issues like this and fixed it? I've heard the TPS may be something to look into, but don't want to start changing things drastically for a smaller issue. I prefer to get a good baseline of the bike and make tweaks here and there.
  5. Electrical Help Please - Unknown Current Drain I know electrical problems can be a can of worms but I’m hoping someone has seen similar issues on husky/ktm before. Troubleshooting tips appreciated. 2016 Husky FC 450 Vortex ECU 0.2 Amp drain found when all stop and off. Findings - Battery voltage at 12.7v when stopped. 14.2v when running. - Amp draw reduces to 0.1 Amp when ECU is unplugged. Why? - Noticed that the fuel pump turned on when I reconnect the battery. Shouldn’t this only happen when I bump the start button? - Removed Fuel Pump Relay, drain stopped while unplugged. Replaced relay with new, drain continues when connected. - Main ground connections at frame look good and tight. - Bike rides fine but battery dies overnight if not disconnected. - Battery replaced, no change. - Other forums mentioned failing fuel relay and rectifier, does that make sense? What/Where is the rectifier? How do I test it?

    2018 MXA 450 Shootout

    The MXA 450 shootout video finally came out. It is almost 20 minutes long! But found it the most in depth review of 2018 dirt bikes around. Thought some people would gain some help and knowledge from it. https://motocrossactionmag.com/the-greatest-450-shootout-ever-its-long-indepth-accurate/
  7. Hey, guys I'm new to this site and I was wondering what size bike I should get. Or what I would fit on. I used to ride a 09 YZ250F a couple years back until some scumbag stole it out of my garage! (never got it back) and I've really been missing it. But anyways I'm looking to get a supermoto for riding on the street and occasionally riding on some trails near me. I really want to get a 450 4 stroke but I'm only 5'9 and 140 pounds wet lol. so I honestly don't know if I will fit on a 450 I was thinking about the 300 exc. But if I could fit a 450 or even a KTM 500 that would be amazing. I don't want to go back to a 250 because I'll get bored of it real quick. Any help on what size I should get would be great, Thanks!
  8. Hi, looking for some advice. No real experience with bikes, financed a 2016 KTM 450XCW after riding a 125RM in a back lot for about a week. Don't have much access to offroad spots so I wanted a street legal bike that I could maybe supermoto. I have some 50/50 tires on there now, and installed a dirt-tamer cam that reduces the power by about 20% (https://www.g2ergo.com/store/g2-dirt-tamer/). For now I plan to mostly ride it on the street, but my buddy is getting a bike soon too and might look at finding some trails. Question: I know the bike is too big for a beginner and honestly is a bit scary, but if I'm mostly going to be riding it around streets and possibly going to supermoto it one day, was seeing people's opinions on if I should look into selling it for a smaller bike, or keep at it and learn this beast. Also, if I do end up trying to ride offroad with it, will I have a terrible time? I financed the bike new, so not sure how much I would lose out on trying to sell it...
  9. Got about 250 hours on my 18 EXCF-450. I've got my suspension dialed in- im a big rider. 1st gear wheelies effortlessly in any situation -as it should. 2nd - 4th gear cant wheelie at all, which is where I need it (mostly 2&3). Its utter shit. My 16 XC-f 350 would wheelie if a light breeze caught the throttle tube in any gear. I ride singletrack/Enduro. I only do practical wheelies to get the front up over logs, small pits, jumps-kickers etc... Dam thing flames out on quick throttle blips. I went down on the front sprocket from 14 to 13- Not much help, but 1st does respond quicker. Looking for advise to get the front end up with a blip and zap. -Praying that the $1000 Vortex ECU isn't the answer. HELP!
  10. On my 2008 rmz 450, at 1/4 throttle there's this horrible studder. It started about a month ago. The bike has about 70 hours on it i bought it later last year and never had a problem with it. The only thing that i changed on it was the header pipe it had the stock one and i tweaked it where it was making a weird noise so i replaced it with a stock one. Things i have tried............................ New spark plug Cleaned the air filter Oil change Checked the valves one exhaust is on the loose side but not out of spec. I may try injector cleaner but idk if thats ok for these bikes. Any help is appreciated thanks in advance
  11. As I was inspecting my new-to-me bike that I just purchased, I noticed there is a grove on the back side of my front brake rotor that goes completely around it, and you can feel it with your finger nail. I have noticed some poor performance, but I figured it was because of the new pads that the previous owner installed just before I bought it hadn't seated yet. However, I've ridden a couple times and it doesn't seem to get much better, if any better at all. Is that enough to explain why when I pull in the brake as hard as I can, it only slows me down a little, instead of going into a stoppie and over the bars (as I wish it would)? Should I look into buying a brand new rotor? I have no pictures of it, I'll try to post some when I can.
  12. Today i flushed the old coolant out, and added fresh coolant to the radiator. When I started it up, it began smoking after 1-2 minutes of idling. I killed the engine and started checking hoses, looking for leaks and noticed some damage to the radiator. It looks like this part was pushed into the radiator, but i'm not even sure what it is? My question is about the damage to the radiator, is it enough to say the radiator is ruined and needs to be replaced? Also, what the heck is this thing that was pushed into it? I bought this bike a week ago, and I've only owned older bikes in the past, so I've never seen anything like this before? Main concern is the smoke from the radiator, but any input or advice would be greatly appreciated.
  13. I recently purchased a used 2009 CRF450r.. before this bike, everything I've owned had carburetor and cables. That being said, I'm certain something is missing here in the assembly, I just have no clue what I am looking for, what it's called or where to order it. There is nothing that really helps in the manual, but if anyone knows the part(s) i need to get my front brake functioning again, it would be greatly appreciated. Here are a few pictures of the setup with the new lever on, as well as with it off. All i know for sure about this font brake, is that the lever i purchased doesn't reach/touch anything.

    2017 crf450r electric start

    any one do the electric start kit on the 17? i see two different part numbers for it 08Z70-MKE-A00 and 08Z71-MKE-A00? does the kit 08z71 come with the harness any everything else or do you have to buy both?
  15. I was adjusting the intake valves and noticed this ! Should this be absolutely be replaced, or is it OK to run ? Its a 2013 450 XC-F with 72 hours. I had been aware of the KTM recall for the 2013 450/500 rocker arm due to poor DLC (Diamond-Like Carbon) coating, this looks to be the same issue to me. I didn't think the recall had applied to my bike since I had entered my VIN on the KTM website, and it only had the fuel line recall come up. Now I'm wishing I could have the warranty work done. You guys think there's any chance the dealer would initiate a warranty for this ? I'm going to see the dealer this week and see what they say. Any advice ?

    KTM 2-stroke Overheating

    I'm caught between a rock and a hard place. My 2010 KTM 250 XC won't stop peeing coolant out of the overflow tube. I've used 3 different radiator caps (two of the oem 1.8 bar caps and one CV4 2.0 bar) and it still continues to pee coolant as soon as the bike starts up. I just recently bought and installed brand new radiators [GPI on eBay for $88 (the seem fine just the welds are a bit crappy and you can see inside of the tubes where the metal from the welds drooped down but there are no blocks)] and silicone hoses (profactory hoses) thinking they were the problem since the old radiators were bent in like bananas. To my dismay that was apparently not the issue. I've had everything apart and looked at. Has brand new base gaskets, head gaskets, radiators, and radiator hoses. I've bled the radiators like the manual says and there are no bubbles like air leaking into the system or being in the system. The jetting is also perfect. The only thing I haven't changed out is the oem impeller in the water pump but it looks to be in great condition. Any ideas on how I can fix this problem before it gets worse? Also, has anyone else had this problem and figured out how to fix it? I ride it in mostly tight 0-10 mph trails and also some 10-20 mph trails.
  17. My rm125 leaks gas when sitting there on the stand with gas off. I've tried cleaning carb to make sure no dirt or anything! Please help! Also my kickstarter is tight when pulling out?

  19. This topic has likely been covered before but I figure my situation is a little different. Im 25 and weight 155lbs. Currently I've got about a years worth of consistent motocross experience under my belt on a 2008 CRF250r. In addition to that I have about 3+ years of street riding experience on various 450cc supermotos'. My question is, when would it be appropriate for me to bump from my 250cc up to a 450cc for motocross? Obviously a years worth of experience on a 250 means I haven't squeezed that bike of its full potential yet but recently I rode a friends yzf450 for a few laps at the mx track and was blown away how much more planted it felt compared to my 250. I'm guessing it was the increase of torque and possibly the small weight difference that made it feel that way. I felt very comfortable on the 450 but at the same time I was taking it easy and could also feel how much of a monster it really was on the mx track and would not be as forgiving as my 250. It may sound stupid but I almost felt safer being able to get over jumps not having to wind the bike out for all it had like some jumps on my 250. Right now im recovering from a broken foot after a pretty bad crash at the beginning of the month so it's going to be a while before I ride again anyways. The other reason I feel inclined to get a 450 is because in addition to riding mx, I would really like another supermoto. You just don't supermoto 250cc bikes its just not worth it. So at the end of the day, should the 450 on the mx track best be left to the much more experienced, or would a rider like me with a year under my belt get along well with a 450. I haven't ridden any of the newer models but I think there is a button to switch fuel maps to tame the bike down a bit. That would probably help the transition some. What are your thoughts? Thanks in advance!
  20. 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.
  21. Need help or advice on picking a bike. My last bike was an 04crf250. So been off the bike a few years. My dilemma is a 2009 rmz450 or a 2012 kx450f or maybe even a 2014 yzf450. RMZ is from a dealership. Was owned and maintained by an apprentice who works there at the shop so I'm sure maintainence was kept up on it, however the guy is a racer so that bike has been through a lot however taken care of. Guy said the bike practically has a new engine and does have some mods, fmf full system, rekluse clutch and forks have been revalved for I believe 180 or 200lb rider, I am 150. And other small stuff. I think price OTD I can get it for is $3K or $$3200. 2012 kx450f. Don' know much about but seems bike has been taken care of decently. Has KYB suspension. No mods really. Just hand guards and pro taper handle bar. And that's really it. Guy said he is pretty firm on $3800 but I'm sure will take $3600 And then there is a 2014 YZF450 that I've had my eye on but don' really want a Yamaha unless someone can change my mind. Looks like it' in decent condition and guy is asking $3700. Any pros or cons to these bikes or personal experience that you guys can share? Thanks!
  22. Anyone switch from a 450 to a 2017 or newer TC250 or 250SX? I have a 08 CRF450 I like a lot but since the new Husky/KTM redesign in 2017 I have been thinking of making the switch back to 2 strokes. I am 37 with 2 kids and mainly ride at practice tracks and maybe one race a year...so I dont ride competitive but love ripping on tracks. So I was looking for some feedback/input from anyone who rode a new Husky/KTM.

    HELP 2012 Wr 450 getting hot FAST

    Here lately, probably the past month or so, my 2012 wr450 started running a lot hotter than usual. It happened right around the time I put some header wrap on my head pipe so I thought that was the issue and left it at that. Well I deliver for a company on my bike and its been warming up here in texas the past few weeks ~80's I decided to take the header wrap off because it felt unbearable riding with how hot this thing is now. So I take the wrap off and the bike still gets stupid hot stupid fast. Now when I say stupid hot I don't mean boiling but temps, but way higher than it used to in a shorter amount of time. Before this issue it could be 60 degrees or so outside and my trail tech fan would never kick on. Ever. The fan temp was set to trigger at 175. Now even when it is this cold out (60's) it can hit 175 in maybe a mile of easy riding. I ride on the street so it's constant air flow pretty much all of the time. The bike does have Engine Ice in it and it is full in the rad and appropriate amount in the reservoir. I started it this morning to see if the coolant was circulating with the cap off and the level would kind on bubble (probably not the right word for it) but it would kind of go up and down maybe a half inch or so every second or two. So I assume the pump is working as it should? Not sure but i've got a buddy who is bringing his stock water pump over and I am going to drain and clean my coolant system with white vinegar and water 50/50 to clean and flush all the junk, if there is any, out of the system and then try his pump setup. I checked my oil and it doesn't look milk shaked inside but I do plan on changing the oil tonight to see if there is anything going on in there which will tell me if impeller shaft seal is bad etc etc. Also, When it's in the garage and running my temps on my GYTR tuner says the engine temp is 150/160's when the trailtech fan kit is saying 180's but once the bike is off they seem to equalize out within 2 or so degrees from eachother. Not sure if that tells me anything but this is far all I know off the top of my head currently, If things change or I remember I will update the thread. The bike has 320 hrs on it probably 98% street riding as this is my daily driver. It is not losing coolant, leaking or burning. Valves are all in spec, checked last night (for the first time lmao) GYTR ECU and FMF powercore4 pipe Oil should be good but I am going to do it anyways tonight. Coolant getting flushed and cleaned along with a "new" water pump this evening aswell. If anyone has some tips or things to check for etc let me know. Thanks in advance!
  24. Hey everyone! I went out to the desert last weekend and decided to record it. We rode mostly tight sand washes. Check it out! PS Turn up the resolution and the cameras were faced too far down but I tried to make it work
  25. i have a ktm 450 2010 and a Kawasaki kx450f and need new spokes to both of them in the rear, the dealer did not know if ktm spokes do fit on the kawa aswell. problem is that he only had spokes in stock for ktm machines. anyone here knows the answer of this one ? both have stock 19" rear wheels .
