75cc gy6 nightmare :S

[padly1995]

Ok as u know i had a big problem with my scoot.
Here is a walkthrough of what was going around with my scooter from last post: http://scootdawg.net/showthread.php?t=54662
There is just so much that i am not writing all again.

Than i changed roller weights to 6g new ones and acceleration was little bit better.
After that i changed clutch to original new one and the take off is now normal.

But this is still not it!
It still dont have enought power (take off and acceleration). And its top speed is only 60-70, but before everithing started it was going around 100kph with same revs that now is going 60-70kph. If i put 7 or 8g rollers in top speed doesnt change, only revs are lower :S.


Whats wrong :S:
Can this be faulty piston or cylinder or cdi, do i need to rejet?

Thanks!
