Yamaha CG50 Jog - mild modifications??
Hi everyone!
This is my first posting, I have just joined today.
My winter project has been a Yamaha CG50 Jog - air cooled 1995 model.
Bought it from E-Bay and took the panels off when I got home, WHAT A MESS!!
So, 4 months later its back on the road, rebuilt and now done 80 miles with the following changed from standard -
RMS 49cc piston & cylinder kit. ( Cheap, but probably less restrictive than a standard Yamaha one).
Technigas standard type exhaust but derestricted.
Mallossi red foam filter in derestricted airbox.
Carb jetted up 2 sizes & needle lifted up 1 notch.
Standard Variator, with washer removed between discs.
But -
I can't get passed 60kmph/38mph!!
The engine revs cleanly, but the scoot reaches 38mph and thats as fast as it goes. There is still more "throttle" to be had, i.e a bit more rpm, but no more speed??
I had 5g rollers (it wants to pull wheelies with these in) fitted so I upgraded to 6g, my local scooter tuner advised that I would get more top speed, but the opposite happened, I lost 2mph!!
Has anybody any ideas what i can do please.

Frustrated, Born Again Biker!!!
