who ported your head.
did you notice any diffrence.
your size sprocket is ideal for top end and take off.
mine does bog down a wee bit on take off but i had no choice. it was use a 32 took sprocked or loose the rear disc brake.
I do most of all my own motor work I dont have a lathe to do any turning but the rest I do myself
yes I do notice a differance in the overall preformance,but I dont engage the motor unless I'm peddling atleast 12 to 15 mph
