What jets? (Modded WR450)
Posted December 11, 2012 - 07:18 AM
It's a UK 03 WR450 Supermoto, YZ exhaust cam, YZ tensioner, full Akrapovic. It was jetted by feel when the camshaft was fitted but I'd like to know for sure that's it's set up properly as it isn't much quicker than my brothers stock WR450 ’04 :-(
1. What size jets should I have? Is there a decent jet kit I can give to whoever dyno tunes the bike?
2. How can I tell what jet I have fitted currently?
3.Anyone know any good carb dyno tuners in SW UK?
4. I have an old style Akrapovic system which is really loud, want to do more track days next year so looking for a new exhaust that has the option to run with a 94db insert and also with out it, can anyone recommend one that's not too expensive? Was looking at DEP S7, any good?

We will help, but you've got to do the work too. First things first, you've got to let us know what jets your running, and then, we can help.

Also, if you upgrade the accelerator pump linkage spring (merge) the pump will work in better conjunction with the throttle.

Make sure you are running a 165 or bigger main jet .
