I have a 1980 P200E that has been recently fitted with the Pinasco 215 kit. The scooter is pinking at idle speeds and also in fourth gear. Also, it is difficult to shift to second, third and fourth. If I quickly gas it before gear change it slips into gear. Doesn't seem right? I have close to a 150 miles on the new kit. Still running in period...It has a standard stroke, 24 mm carb, SIP road exhaust, bosch w3cc spark plug, 130 main jet and mixing oil to gas at 3%. Timing was set at 20 degrees? Thanks for any help (dunker)!
