I just have a few questions before I buy this kit. First of all, I have a 66cc Grubee Skyhawk. Will a pull start or centrifugal clutch mod affect this kit? Also, my bike only has 8 speeds on the back wheel. Will this be alright? What size front sprocket would you suggest I get for a mix of hills and flat sections for where I live? I was just thinking a 44 tooth you be fine. Thank you so much for any advice you can give me!
