****, I have a question, Im only getting 22MPH full bore. I have a Chinese 66 cc engine with a 44 tooth rear sprocket. I want to get at least 35MPH with a cruising speed of 25MPH. Ive installed a NGK spark plug gaped to around .o2o greased the primary gears with blue marine grease, drilled a 1/4" hole in stock exhaust opposite of the primary outlet. Im running regular gas @ 20:1 put on a better air cleaner, but still have the 50cc stack carb. Any ideas how to increase my speed, I plan on getting a 36 tooth sprocket if this poor girl can come up on the cash and a good carb from spookytooth also. Thanks!
