  1. Hello all, I am having an issue with a 2006 Honda CRF50 and looking for general guidance for troubleshooting tips. The problem I have is the bike will only run when the choke is on. I can turn it almost 98% of the way to off and it will run on idle. When I push the choke to the full off it will die. I have cleaned the carb like it was in a Hospital Clean room and YES the pilot jet is open and clean. The card has been dipped in carb cleaner for 3 days also. As I said the bike will run on choke and if I raise the throttle to a high rpm and turn the choke off the bike will start to bog down and die. I thought that by getting the RPM's up I could tell if the bike would run fine of the main jet. But seeing that it will not run with high rpm running off the main I think I have another problem other than the pilot jet. Does any one have any sound advise as to what to check next and maybe even help explain why it would act this way i.e. vacum leak, too little fuel, too much air, etc. I want to understand what causes the symphony to be a better mechanic. Here is a video of it idling on choke and what it does when I turn the choke off. Notice how little choke is actually on when it runs and just moving the choke lever that last little bit makes the engine die. https://www.youtube.com/watch?v=f4XB9FK7qnI&feature=em-upload_owner#action=share
  2. I have a klx110 pro circuit. and the exhaust is cracked right above the foot peg, I was wondering if its still okay to ride it? I`ve seen people ride without an exhaust so I thought it was okay. ( I do stunts on it so I'm kind of concerned if I should continue riding it )
  3. So my mate called and said, I'm fed up with riding road bikes, especially with all the new speeding laws in England now, lets sell our road bikes and buy dirt bikes. So I said, yeah, ok and without doing anywhere near enough research or knowing which discipline I wanted to get into I sold my fireblade and bought a CRF250R. Fast forward 6 weeks and armed with 2 MX practice days and 2 enduro days experience, and a ton of reading about dirt bikes, I have realized that enduro is more my bag and I've probably bought the wrong bike. My decision now is, do I make my Honda trail friendly by doing mods like a G2 throttle tamer, heavier flywheel, bark busters etc orrr, do I sell it and buy an enduro. I've already decided that I'd probably go for a 2 stroke if I did go down the enduro route as I'd be happier to work on it myself in the garage. My budget isn't massive, maybe 2600. I've been looking at the KTM 250 exc. Any thoughts or advice is welcomed.
  4. Hello! somebody know how to run a 4 stroke lighting stator on my Suzuki RM250 2005, i bought a lighting stator from a Suzuki rmz450 2005. Conetor and colors of the stator are the same so i think the only problem is the timing or the advanze of the flywheel. does anybody know if is possible make it run. The bike actually start a couple times but without the throttle dies soon/ I leave you a couple of photos of the lighting stator in the bike and the wiring harness of each bike. Thanks bros!
  5. So, I took my 03 yz250f out riding for the third time since I've bought it. I never had any overheating issues till today. After riding it around for a bit I stopped and I let it idle (which btw has a hanging idle) for around 1 minute. Out of nowhere it started spitting coolant out of the radiator and the bike was super hot. I dont know if it being 100 degrees outside and idling might have affected it or my jets are dirty which is causing it to idle high and run hot. Ive also noticed that the gas is boiling inside the 5 gallon desert tank that sits directly on top of the carb and pipe, and it remains boiling all the time I am riding. The bike does not overheat or spill coolant when I ride it. If It starts spitting coolant at idle and I ride around for a bit right away, it stops leaking. I opened the radiator cap and revved the bike, the coolant was spitting out and bubbling, however, with the cap on the overflow line does not spit any coolant or even air for that matter. If it overheats at idle, the coolant comes out of the radiator itself and not the hose. Could it just be these bikes do not like idling for more than a minute or is my head gasket blown? Why does the gas boil all the time? Anybody have any thoughts on this? Thank you very much!
  6. I found a bunch of twigs and crap in a vent hose going from what I think is the starter motor to a big T that connects to the top end vent as well as the air box. Im guessing the guy submerged the bike enough that a bunch of crap got in through the air box but maybe somebody with more experience can help me out. Is that spot in the engine that the hose is going into pushing out or sucking in? And why exactly are there two vents from the engine? Ive only seen a crank case breather hose from the air box to the crank case with a T in the middle but I could be wrong. Heres a pic: Im guessing finding a bunch of twigs and grime just on the inside of that hose is a bad thing

    Vortex tuner adjustment

    17FE450 , read my plug thread... sorry De smogged, reeds removed, fmf slip on, oem map switch, vortex tuner. I have always felt like this bike runs on the lean side, even after upgrades mentioned above. It's just feels like it heats up quickly and runs hotter than my other 4 strokes. All of the vortex trim switches are in the neutral (5) position. Map 1 (on the handlebars switch) is preset to vortex power map Map 2 on the bars is preset to vortex traction map The plug pictured has 30 hrs. Any 4 stroke guys out there want to throw in their .02c? Any down side to richening up the vortex 1 click each on low, mid, high?
  8. I’ve been obsessed with dirt bikes since i was a kid but have never been lucky enough to own one but here in the near future when i have the money i would like to buy my first bike. I’m tall and skinny (6’8” , 150 lbs) so i would like a bigger bike. I’m wondering what you guys think is the best bike to learn on. Also i originally wanted a 250 2 stroke but then heard for beginner adults to look for 2 stroke 125 or a 4 stroke 250 is there any validity to this? Thanks
  9. I have a 2008 ktm 250sxf and I'm having a lot of problems with it. I missed yesterday's race because it wouldn't run right. It's idling really rough. Every few kicks it will back fire really loud when I get it to run it will idle rough and when I give it gas it will bog then when I release the gas it will rev high and is hard to come down. I will give it the smallest bit of throttle and it will stick at a really high idle and I have to rev it hard and quick a few times for it to come back down. When I put it in gear and try to ride it slowly it just tries to take off and it doesn't even feel like a high idle. I have to ride the front and rear breaks for it to not take off. I can let off the throttle and put it up to 6th gear and it still keeps going. I just had the entire top end replaced. Cylinder piston rings etc. I cleaned the carb several times cleaned all of the jets and still nothing. Replaced the throttle cable even disconnected it and still nothing. If I disconnect the throttle positioning sensor it runs a little better but is still pretty rough. I used a multimeter to test the tps and it seems fine other than when it's at "idle" it's at 1.14 on 20k I give it a little gas and it sticks at 1.17 until I rev it hard a few times. No idea what it could be. Needle and seat seem fine I'm stumped on it. Please help!

    2012 WR450F - STOCK VALVE SHIM SIZES

    Anyone with a 2012 WR450F remember what size shims were in there originally? I want to know how much valve stretch I have without taking them out and measuring. Mine are all between 1.78mm-1.85mm thick. Thanks
  11. So I just bought a 2017 rmz 250 and I was wondering how often I have to rebuild the top end. I figured as long as a keep the oil changed every 3 hours and a new oil filter every other oil change and keeping the air filter clean I wouldn't have to touch the top end very often but the book says every 20 hours and I don't think I can fit that in my budget so often, any opinion is appreciated, thanks.
  12. Hi! I am wondering if a 2 stroke would suit my type of riding best. I do trail riding, but not stuff that's really intense. I am 5'5 or 5'6. I currently have a KLX125 and I like it, but need more power! I am thinking a KDX200 would be the perfect two stroke, if I were tall enough. Same goes with the XR250r. Any suggestions would be great!

  15. Hey guys I recently bought a 99cr125 long story short it needed a clutch cable and perch. I ordered new clutch cable and a cheap 10$ perch and new boysen clutch basket and plates. The bike runs great it's just super hard to pull the clutch. I lubed it very generously and I have it routed correctly i don't know what it could be I'm not the weakest dude out there but man does it kill my hand and fingers and it's quite annoying. Anybody have some advice? Thanks

    Question about oil in my motor

    So I bought a ssr 125 very fresh hardly riddin bike and I went and changed the oil I put what the book said 10w 40 regular car oil and after about a 30 mile ride I was looking thru the book and see. That it needed 10w 40 4 stroke motorcycle oil so I changed it the next day do you think I hurt the bike at all ??
  19. In your opinion, which Factory Team would you race for? -Suzuki -Honda -Kawasaki -Yamaha -Husqvarna -KTM -Also, 2 stroke or 4 stroke?
  20. Hello all, I know this is a highly debated topic and one that has probably been discussed at great length. I apologize in advance for opening up this can of worms. Unfortunately, when I have done searches both on this forum and google, virtually all the threads I have read are old (2004-2010, maybe 1 thread from 2011'). I have not seen anything (2013-2017) regarding this topic. I think with progression of engineering that reliability on both 2 strokes and 4 strokes on 2014 + bikes is vastly superior of that of 2004-2010 bikes. (maybe I am wrong....) My background: I had a Yamaha RT 100 and TTR 125L back in the day (my only dirt experience). Then ended up with a GSXR 750 after college, then a KTM 690 SMC supermoto, CBR 600 track bike, and then a Husqvarna 701 Supermoto. So I am not new to motorcycles but my knowledge of dirtbikes and dirt riding is pretty limited. Obviously coming from a street bike the maintenance and service intervals are substantially different than a dirtbike. Hell, even my track bike does not require all that much maintenance and I ride the crap out of that (change oil every few track days). I want to get a dirtbike that I can go ride some trails (I will probably just putt around) and occasional try and ride a MX track (I imagine I would be very slow. I road a MX track back with my TTR 125L but that sucked because it had no suspension- amongst other things). So while I do not need race bike power, I would like suspension capable of hitting some MX jumps. Hence why I do not want a trail bike like a TTR 230 or CRF 230. I want something that would be able to actually take some jumps if I get to that point (I at least want to try and progress to that point). My question is: Would a 2 stroke (no older than 2007') be easier/cheaper to maintain than a modern day 4 stroke (2012' +). I have read 2 strokes need a top end rebuilt every 20 hours. Some say 30 hours, and I have heard people not racing run 2 strokes for 60-80 hours without a rebuild. Then they say 4 strokes are full engine rebuilds when they go (and the cost of the actual pistons and rods are significantly higher on the 4 strokes?) I will be riding not nearly as hard as many people on here would. I understand the powerband difference and all of that. I am more concerned with wrench time and cost to ride over anything. P.S. Holy crap, people have their bikes overpriced on craigslist. I am trying to pick up a small bike for my fiance and I am seeing like 2004-2007 TTR 125L's for like $2,000- $2,200..... a 10-13 year old small displacement trail bike???
  21. I am looking at getting my first dirt bike, I have ridden quads and have always wanted to ride bikes. Before people start sharing there opinions about 2 stroke vs 4, this is what I'm looking to get out of the bike. Something that is fun and easy to learn on, Period. Don't worry about maintenance costs or the "thrill" of 2 strokes etc... I originally though 2 stroke but my buddy has a 2 stroke kx250 and i felt like i was out of control every time time i gave more then a touch of throttle. Is this because I'm new to riding dirt bikes or is this a 2 stroke thing. I want something that is easy to control and I like what people say about the smooth power bands on the 4 strokes. Cheers, Kyler
  22. Which bike would you buy and why? KTM XCF 250 Yamaha YZ250fx thanks!
  23. I own a 2013 TXC310, and would like to hear any suggestions to make it competitive in the hard enduro scene (specifically re-gearing). -SLR Fanga dagen

    WR250R vs CRF250L

    I'm looking at these two bikes as dualsports for the price and mpg. Even though I just said I'm looking at these two as dualsports I plan on putting slicks on them because I already have a dirt bike. I don't plan on any crazy mods with them except for maybe an exhaust. Which one would you recommend and why? And if you want you can throw in the CRF250L rally model as well.

    TTR 225 Suspension

    Hey all, I am new to the forums and dirt in general. (street rider) I am looking at getting a TTR-225 this week. I know that this has a few threads already but I was unable to find links to products with an exact fit. I was wondering what the best suspension would be for this bike. I am new to upgrading suspension so would I just need stiffer fork springs, what exactly do I need to change? And what difference if any do RaceTech gold valves make? I won't be jumping the bike, I would just like to have something that has stiffer suspension than a stock TTR-225. I will be doing trail riding in Georgia, with mud crossing, mostly decently packed dirt/clay what would work best for my application? And who makes a good skid plate for the bike? Please provide links to all things mentioned. Thanks! Nick
