Re: I'm new i need advice....
Welcome to the forum. I hope we can help you get a little more from your motorized bicycle. You've recieved some good advice but I'll ask how many miles do you have on the engine? A new or low milage engine will not perform as well as one with at least a couple hundred miles on it. They run better as they age.
Also, what fuel/oil ratio are you using. The kit recommended 16:1 we've found to be a bit too much oil. Drop your mix down to at least 24:1, 32:1 is even better.
Make sure the cylinder head fasteners are torqued to 120 to 140 inch pounds. Loss of compression due to a cylinder head gasket leak will kill preformance.
Good luck. Hope some of the suggestions help.
