So I got a 66cc with a shifter kit on a 29'er with a SBP expansion chamber going only 35MPH TOPS. So in 7-8th gear it wont rise in rpm's it will stay low with an uneven motor sound. I have the cns carb and would like some tips to make this work out better. Would different jackshaft gears help? any help is appreciated.
thanks.
thanks.
