Performance Upgrade Part 4
« on: April 22, 2016, 08:08:41 AM »
Has been a while since I work on my Scooter mainly due to the winter season, I was snowboarding instead of riding.
This time I installed a 63mm big bore kit plus high lift cam. Installation wasn't too difficult, take no more than half day. Performance gain on this BBK are amazing, especially off the line. My setup includes BBK, high lift cam, performance CDI, pipe, variator, clutch spring and 28mm carb, I was able to hit 70 mph+.


Installing BBK doesn't require removing the motor, but it does make it easier, especially when removing and installing the Piston.


 



Got an extra head, For future plans, gonna send my stock head to have bigger valves install plus port and polish

You were able to reuse the stock head with the big bore upgrade?
