I think its around 120/125 main,more interested in wether exhaust is ok to use,I think not myself
i would run a 128 to start with, any exhaust can be dialled in to any carb with the right jetting

It was advised for him to get a bigger main jet as soon as possible but it looks like he didn,t bother. now its dropped on my doorstep to repair. cheersmark wrote:i would run a 128 to start with, any exhaust can be dialled in to any carb with the right jetting

why not use a jl3?
would have thought a 125 main would be ok - ran a 118 main on an indian big bore for a very long time and was thrashed to within an inch of its life
only my personal opinion though
