    Full throttle all the time, 20 mph max speed

    Hello, motoredbikes gurus! I have been a long time lurker, and built my first bike over the course of the last few weeks. Everything went really well, and I carefully followed the advice of many of you. I am currently in the break in period of my bike. I am using a 32:1 mix. I have been through...

    Keep on the lookout for 1E53F 79cc Huasheng Kasei

    It looks like there is a new engine from Kasei to replace the 63cc which is currently the biggest two stroke available for friction drive. It is 79cc and the model number is 1E53F. I still haven't found a place that is selling it. I contacted Huasheng directly to see if they will sell it to me...

I have a 2 stroke kit on one of my mountain bikes and when I first set it up I did not know the threads on the front mounts were removable and I had to use the universal adapter thing so I let the threads sit on the front bar. eventually they shaped off and left...

    No spark, no start.

    Got myself a 80cx(66) engine for a few months new slurry of problems all fixed (except exhaust). Now I went to start it the other day and when I pop the clutch the engine got ripped out of the front frame mounts and pulled off to the side. Now I have it all put back together since then with new...

    would a two stroke run on straight WD-40?

    It seems crazy and I don't want to ruin an engine tested it myself obviously but something tells me it may be would? What do you guys think? I bet he would actually run real good on 50-50 WD-40 and gas but again I'm not going to ruin an engine just to test my zany hypothesis here, and I can't...

    Bike too slow

    About a week ago I bought a 2-stroke 80/66cc bike kit. I installed it and after startup problems at first I managed to get it running smoothly, the only problem is, it is way too slow. It struggles to stay at 20mph with the throttle wide open. I checked the carb and the throttle runs fine, so...
