I have a Kymco cobra racer with a super 9 air cooled engine and
a tecnigas pipe . It's stock 50cc.
I did not build this scoot. I bought it this way.
The problem is that the clutch does not bite until it reaches 8000 rpm
It's great when its moving in traffic because it right at the power band
but acceleration suffers as it's not pulling through the rev range.
It stays between 7500-10000 rpm.
I have used lighter weights and improved the acceleration and heavier weights
which improved top end.
Right now it tops out around 52 on the clock ( not GPS )
With slightly heavier weights it tops out around 58 but the acceleration suffers.
The contra is good because when I go up a hill the rpms stay constant and the speed drops.
All my other scooters have started to " pull " around 4000-5000 rpm.
I was considering a 70cc kit but many give more low end grunt and seeing as I'm not engaging till 8000 rpm would this even help ?
Thoughts or suggestions would be appreciated.
Thanks !
