Good evening sports fans.
Ive managed to get my hands on a second hand AF Stage 4 barrel and piston for my GP 150.
Can I trouble you gents for opinions and any tips for setting it up with my sterling exhaust and 28mm Mikuni.plus expected performance, top speed, tourge

Cheers..

I used to ride with guy who had one.
Similar set up but with a clbby.

Weren't bad, just gear to suit the pipe.

before you worry about setup make sure you thoroughly check the bore, piston and rings for wear and that they are within useable tolarances as if they aren't then no matter what you do it won't set up.Also personally for that barrel a 28mm carb is a bit to big a 24 would suit better
