Don't waste money on a kit. It'll run fine with stock jets... just back out the pilots to 2 1/2 turns. Easy and cheap... including the fact that your gas mileage won't suffer.
If you REALLY want to go up on jets, I would go up 1 size on slow jets, maybe 1 or 2 sizes on high speed jets. Just remember that you'll lose some gas mileage.
Don't bother with the needle (hence the reason I say not to get a kit)... stock is fine.
I've used these guys... prices aren't the BEST, but shipping is pretty quick.
