Jetting? where to start?

Final Numbers:

Exhaust: DMC

Intake: CFM UNI, Ported Pro-Design Manifold and VF3's with ported inner cage

Wiseco Forged Piston Stock Bore and Wiseco Crank


Carb: Mikuni TM28 Part Number VM28-418, this is a flatslide mikuni carb.

Pilot: 32.5
Main: 250

These are the correct jets for this and similar setups
 
See what I meant back there man?

If you were on a stock 26mm carb your main jet woud prolly be up in 270 or higher range, but because youre on a 28 mil you had to jet down cause your carb pulls more fuel through through the jet.
