I was out for a cruise a while ago and everything was running fine. All of a sudden I start to get really low engine power. I hold in my clutch and then release it and it powers up like normal for about 2 seconds then has no power. When I hold in the clutch the engine revs to about 4-4.5k rpm and stays that way. I can keep releasing the clutch for more power, but like I said it only lasts for a couple seconds and I don't want to damage the clutch so I only did that about 4 times. I was thinking it might be an idle screw problem, however I have no idea where the screw is at. My engine never came with a manual, and googling has turned me up nothing. Is it the screw that the clutch cable go's through? I tried turning that but it appears you need to be Thor to do it. The engine is a 2011 Skyhawk gt5, stock everything right now except spark plug and cdi.
 
uhm, in all honesty from the sounds of it, it sounds like the clutch is relieving some kind of pressure from the motor, I'd say check to see if your chain is properly tensioned.
 
ok so its not to much oil next thing is try riding with the gas cap loose just enough to brake the seal to see if its a vent problem might be vapor lock and thats easy to fix
 
Sounds like a faulty gas cap then. It's supposed to let air in as fuel is pulled into the carb. Yours is air tight which is pulling a vacuum inside the tank. Your engine is starving for fuel and losing power. You're better off leaving the cap loose until you get a new cap.

What carb are you using?
