Not enough information here on TT for you?

From actual owners of the bike:excuseme:

Who live, breathe, and sleep all things WR:banghead:

Who have done what can be done and reported on it :ride:

Some one hit me, please:smashpc: :ride: :ride:

I was looking for the yamaha jet kit for the 07 wr450 and could not find enough

info on it here, sorry. Everyone said to use the 06 AIS kit but the jets are different. I wanted my stock exhaust and didnt want to use J.D kit.

Thought it could be helpful. It helped me.

I was being facetious - don't apologize.

BTW, I'm using the stock exhaust without the insert (the whole thing - just left the spark arrester screen in) and am using Indy's guide on jetting - JD Red #5, 168 Main, 45 Pilot, 65 Starter, 60 Leak, ZipTy Fuel Screw 1.5 turns out and the bike is a rocket:thumbsup:
