I found that with the bike ran better on half throttle with a 106 main jet. just on the verge of 4 stroking at wot.
as I reduced the size of the main jet I could open the throttle more and more until ive got a 96 in now and it runs the same on just over half as it does on wot.
but no better? why is that?
i'm gonna keep trying going smaller with the man jet but am scared of going too weak and meltdown.
think ill do a plug chop first with this jet.
the bike runs brilliant low revs as long as I don't open the throttle too much then as the revs rise I can give it more and more throttle.
