Once again, another one of my dumb jetting questions. But i get to order my toomey's ($359) from rocky mountain atv most likely tomorrow, already have the K&N's with outerwears, also the motor has wiesco's still on stock bore. I'm currently running a 210 main and except for the pistons everything else is stock. I just want to have everything ready so i can ride. By the way, one more question should i just change the main's to a bigger size or go ahead and get a jet kit with new needles, and of course new jets. If so what kind of jet kit should i get, i've been looking at some dynojet jet kits (stage 3) it's $82.50 from dennis kirk. Thanks for any help.

 

If I were you I'd go with a 280-300 main and a #30 pilot.The pilots you'll prolly have to get from your local Yamaha shop but the mains you can get pretty much anywhere.You'll be extremely impressed with the difference the pipes make.It'll be like a totally different bike.Good luck.

 

thanks FBOMBERS, one last question do i need to get a jet kit because of the different needles? Or is there really that much of a difference? Once again, thanks.

 

I've always had good luck with the stock needles in the stock position but it depends on where you're located.I'd try the stockers and go from there.
