Would I be correct in assuming that I should go up 2 on the main jet to a 112?

Whilst I am ordering a 112, any point in getting a 114, just in case?

I think a 112 will be sufficient + maybe richen the air screw a notch.

Ah, OK, I haven't ordered any yet. That's a big jump 110 to 115 though :o

this is not an air screw but a mixture screw... Try both 112 and 115 and see what happens....
Size matters!

Just to finish this thread off. I have decided that the exhaust pushes the main jet needed to a 115 as Ducksta recommended.

That's interesting, I have Road 2 on my boys LML150 Reed valved PX and I THINK I only went up one size on the main....still running though so panic but will keep an eye on that.
