uhh. ok. well yesterday the bike ran 35mph. dont ask me how i dont know either. it was running like this for 14 miles. idled fine..then, in idle, it just shut off. wouldnt start again. today, i started it, went around a quick ride, without idle, and top speed full throttle was 16mph at best. and dont idle.
the idle screw has an impact now( as of 10 minutea ago), before it didnt. i have no idea why the hell it wants to work now. i didnt do anyting. when i screw it all the way in, the chain moves and the back wheel moves very fast. and when i unscrew the idle screw a little, it slows down. after 5 or 6 turns out, theres a stage in the idleing wheere the chain doesnt move for about 3 good seconds. the engine stays on. chain dont move. so after 3 seconds, theres a double clicking noise (click-click!) form the engine, and that enables, or triggers the chain to move, turning the back wheel. so now, the chain moves the back wheel (slowly) for about 5 seconds, then slowly stops and goes to that 3 second period of no movement. and repeats this cycle.
the engine also gets super hot in the idle. i let it idle on the stand for 5 minutes. the exhaust (the part under the pedal) is really really hot. i spit on on and it sizzles, and the spit bounces off. hot enough to burn skin if touched for 1/2 a second. i applied very very little gas. i just let it idle.

I missed my job orientation because thinking from yesterday, th ped was going 35, it seemed great. then i get ready, wake up early and hop on the ped and all this happens.
