With my experience, the Toomeys like a 290 to 310 or 320 is some cases. Unless you have porting or other big mods, you shouldn't really need more than that. You could definitely try the 330 and see how shee does and work from there, and you probably don't need a 30 pilot, maybe a 27.5, and 4th clip on the needle. All banshees run differently, so it's impossible to say what one machine may be good at.
Make sure to read the plugs after you make the change, and don't do it all at once, do the mains first and then move step by step.
Lincster, I'm definitely not trying to disapprove your statement, there are some situations where a bike will want more fuel, mine is one of those. Have you ever checked for some small leaks around the boots or intake gaskets?
Later fellas.
