Hi!

I have an AF01 engined Peugeot. Setup is as follows:

Polini contessa
Malossi head modified CCR 7.3 squish 0.9
19mm Dellorto and Boyesen reeds
Polini variator 6x7.5 gramm
15x740 belt
Final around 7.5 /15/33 primary/
Two pipes both for torque one a bit stronger one revs a bit higher neither does anything over 8k revs.

Now it goes 48-50@7500 with very good acceleration.

I would like to push it to 55 at least without losing much acceleration.

Questions: would it pull a 16/32 primary?

Higher reving exhaust or stage6/naraku intake? (I would like to keep the airbox) Any other ideas.

Af01 means short stroke so you have a 65cc with the kit. If it's a 47mm.
Where do you live so I can convert your ccr to psi.
.9 squish is safe for daily riding, .7 squish is perfect for higher rpm road racing.
Where did you find 15/33 gears? It would be awesome to get some for my kymco. If you have a way of finding another set please let me know. I would go with 16/33 if they mesh correctly.
You will need very tight clutch springs to get you going.
You must drop roller weight if you want to go over 8k rpm. These shorter stroke engines make better power at higher rpm than the longer stroke af16. You should go with 6g rollers.
You may want a higher revving exhaust.
You will need to upjet for the higher rpm you will be seeing.
