just ride the thing man:woohoo: if it crackles on decel it may be a bit lean and when you hold it wide open if it feels flat also lean, just a bit of fine tuning is all thats needed. PS aaron I was checking out your arse:blush: whoops I meant style:laugh: on Saturday,you are a loose unit and I could tell you where having fun;) awsome stuff mate.

Yeh mate,just adjust your fuel screw out 1/4 a turn at a time have a ride between adjustments. Remember where you originally started from (write it down) so that if you f**k it up you can always go backB) Jetting will also change with Temp,humidity and altitude.
make sure bike has warmed up first.

I think there is a jetting guide on this forum somewhere which would help ya out.

The fourstrokes have a fuel screw the 2 bangers use an airscrew basicly do the same thing but different if you know what I mean:unsure: You can still adjust your standard carby its just a bit fiddlier than it should be. unless you have a special tool,you have to rotate your carby to get access to the flat blade screw,You can get a fuel screw from ballards for about $30 fairly cheap they make life easier.

the black screw with the knurled top is the fuel screw Im talking about,it replaces the standard item that sits in the front of the carby underneath.
