Methanol Jetting


Port King

Recommended Posts

Hey there,

 

I've got a 535 runnin with 22cc domes, two 35mm VM Mik. carbs the intake is Honda 250. V-Force.

 

My question is; I was running 148 main jet. Now i've installed the power jet kit with extra wide bols and Trinity 50W-TI needles.

 

What should i try out for power jet and main jet starting point ? I think there a equation to find your jet size.

 

Your help is very apreciated. :cheers:

with methanol your usually going to have to drill the jets to make them the right sizes..

 

did someone do a conversion on them for you or are you just adding the power jets yourself?

 

the average size dump tube/main jet is drill bit size .116 with around a .093 power jet..

 

though with the bigger motor your probably going to need the dumps and mains to be around .120 and a little smaller on the power jets..
