Ok I have a 69 Ciao Just got a set of bravo wheels, Variator, and clutch
Was going to go with the simo circuit pipe
and my main question is can i do it with the 43mm kit or I need the 46mm?
What is the best kit? Was looking at the 70cc olympia 43mm and the olympia high compression head any thoughts on the?
How hard is it to grind the case for the 46mm? Needs to be done at the machine shop? WHere do you grind it at?
How much dose putting the different gears in the trans help out?
