What up? A bbk wont turn it in to a rocketship or anything.. Bbk's really only give about 5mph? but the torque is different...
After a bbk, the cvt,carb will probably be way off.
It was a smaller kit as well...
No numbers were ever checked i assume? squish band?
It's possible THAT is the culprit....
Still have the oem carb?(Any re jetting?) OEM pipe?
