Mikuni jetting for methanol
Posted: Sun Feb 24, 2013 12:41 am
Hi,
I'm looking at running a Mikuni TM32 on my M/F 100cc bike.
Can anyone suggest some jet sizes to start with for running methanol?
Main jet, idle jet, needle jet etc.
The carby ships with the following gasoline setup:
250 Main Jet
45 Pilot Jet
389 Q-2 Needle Jet
5FP17 Jet Needle
831-39012 4.0 Throttle Valve
I presume the main and pilot jets are going to have to flow at least twice the fuel of the standard jet.
I guess I need to work out the gap between the jet needle and the needle jet and calculate a needle jet which will flow at least twice as much fuel with that jet needle.
I have no idea whether or not I'd need a different throttle valve.
Thanks,
Chris
