Re: Bought bottom end from Boy Go Fast, should I be worried?
I have a bgf 48 cc and I think Map Bike has a 66cc, mine has been good and is almost three years old. I got the angled clutch arm from bgf several years ago to go on my grubee, the arm angle and length keep the clutch cable aligned with the cable boss better preventing cable wear at that point. Also keeps the cable end out of your leg when pedaling.
Your results may not be the same,Greg
