this is my first venture with a motorized bike but not with 2 stroke engines as have been playing and racing outboard hydroplanes since the '70's but i'm getting old.....er.....and decided to put a motor on my bike. now that i have it broke in i went for some speed spurts. the prob is that it runs ok [all china crapynes conciderd] for about a minute or so then it suddenly slows way down. in the outboard engines [2 stroke] this means to lean most of the time. so i played with the needle. no good. i opened up the jet a little bit. motor lost some power and speed but no affect on the main prob. before i get all wrenchy or throw the thing in the lake i thought i would run it past you guys. btw this only happens at full throttle.
