runner vx125


Do i need to upjet with a PM61 on my 2007 runner vx125?
i yes, what jets?




you got 2 possibilities !

a 10% higher mainjet with your original carb (is it the 20.5??)


or (and i think this is the better way)

a 25 Carb 4100000 with manifold P2150403and Reed Valve plates M277054


the problem is that the PM exhaust needs high refs, to get a good performance with the 20,5 carb

with the original carb you cant get the right ref
