I want more speed out of my 107cc stroker motor
Af18 block
50mm fully counter crank
And idk wat size of a bore.but its charmo
All ported and matched
7:1 gears
30 oko( 145,58)
Ct chrome
Ncy drive line
Daytona ramp
Polini guides
Zx trans. Ncy torque plate
42.9 weights( 8g, 6.3g weights)
1500 center spring
3000 clutch
3 pole stator

My bike feels like it revs really high and doesn't pull as much.
What should I do?

You know for sure the crank is a 50mm stroke? What are the port durations now? What was ported on the bore? What exhaust is being used?

hey fullrace what did you to fix it. i have the same problem 50/50. my other motor 72 corsa mini stroked pull and screams more hard...
i wonder if my clutch is not holding up from mid to top end..my bottom end is really good yanks hard..

well how fast is the top? And what are you using for a drive face. The aluminum one or stock?

Man, that's a pretty good rate of knots for a littler scooter!

What roller weights you using. If your revin out on mids and top you might be a bit light on the rollers. We have to start somewhere to figure this out. I have to go will chime in later.

i have 7-8grams in now.

Well I thought about this and my conclusion may seem simple but I would like you to try 9gram weights. If the 9's are to heavy you can offset the 8's and 9's together. Here is why. You have sick bottom end so I suspect the rear end set up is right. If you where revin out on the bottom I would assume it would be the clutch spring, the clutch, to light of drive face, or to light of rollers. But its not so try this and let me know.
