bro

always rejet in the ff order
-PILOT JET
-JET NEEDLE
-MAIN JET

the carb jets are additive, meaning the pilot jet will have some effects also
in the mainjet as they are additive.
so tune the pilot jet first, once ok, then proceed to mainjet

Depende sa Mekaniko siguro ^_^ I used OKO 30mm, so far OK na OK naman. Mas nahirapan pa sya sa Koso 28mm at Keihin 26mm bitin sa hangin sa FCCI cams.

@TS
try mo 35 or 39 kapag ayaw mag taas ka. Naka CDI ka na ba?
