  1. Tech/Setups for Supermoto
    Hello my name is Timo and I live in Germany, please bear with my English if something is wrong. At the end of last year, I had an engine failure with my Yamaha WR250X, because the alternator must have loosened from the crankshaft. Over the winter I had the engine rebuilt by a mechanic and...

    Hello all, So I built a 2011 kx450f supermoto and cannot figure out what is wrong with my bike. At a cruise in 4th gear it feels like my bike pulls back for a second and then will do it again at the same speed. It does not seem to lose any rpms, engine sounds fine. I was thinking maybe...

    I need help, run out of ideas. Engine starts to knock suddenly. It's knock at idle below 2000-2500rpm. Sounds really bad and I've got no idea what is this. Was replaced the piston because of slack and clutch basket buching (it has grooved a little). Was checked connecting rod and crankshaft its...

    Howdy y'all. I was on my way to my mechanic yesterday for some maintenance work. About 1/2mi away from it, I came to a traffic light on red. Immediately after coming to a complete stop, I was engulfed in white smoke. The oil was leaking badly so I pulled into a gas station. Not knowing what...

    Hi all, I'm new here but couldn't find much on this. My timing chain recently jumped a few teeth and bent a valve so I'm looking for a motor or sell as is. Is this a common issue because I've read a few threads on here where people's heads are "bad". Is replacing the head advised or the entire...

    Hey just purchased a new to me 1986 xr250r (street legal) and looking to add a few mods to "open" it up a bit more and maybe turning it into a true Sumo. I'm currently working on a smoking issue with it that is being handled ASAP, and since I have the motor off the bike I'm wondering what I...

    I hope this is the right spot in the forum for this. I am thinking of buying a bottom end from a guy on craigslist, and then rebuilding it for a DRZ 400 project. He doesn't have much info on it. The engine number is K419 - 140185. I've been searching for a while now and found that the K419 is a...
