I got everything on my bike the other day and I put 16:1 fuel in it. It would not start. I am getting spark. fuel is in float bowl. the clutch is good.:-|| The motor just makes a "thup thup thup" noise when i pop clutch but thats it. I have tried going faster to no avail. What is wrong!!! :-||

Have you checked for spark? How about fuel? Double check your wiring? If your kill switch is hooked up have you tried to start it disconnected?

I know I have ran into many motors that the clutch needed to be adjusted right out of the box. They can slip so bad that you are not turning the motor enough over to get it to fire.

also try running 25:1 fuel mix 16:1 is to high i also find that 93 octane helps smooth things out and make shure the plug isnt fouled with oil
