I want to buy a couple main jets (170, 172). For an 04 wr 450. Where can I buy these? Anyone know. Thanks S.

James,

Thanks again, I have yet another question. if my bike 04 wr 450, is revving out fast. (red needle 5th clip, 168 main) if I increased the main to 170 would it not rev out as quickly? And if I went one step further to a 172 would it be too rich? Thanks for your time. Cheers S.

The bigger main jet will be more likely to run rich and cut-out at full throttle. The main jet is easy to change (~5 minutes), so try the next size and compare. Run the bike at full throttle to the rev limiter and if it sputters before revving out, you'll know it's rich.

James
