08 YZ450F Jetting

6 posts in this topic

Any recommendations for base jetting settings.

2008 YZ450F - just installed Dr. D Stainless Full System

Jetting is currently stock. Ride mostly in 70-80 temps MX in Kansas City.

Total newbie when it comes to jetting so the simpler the explanation the better.

Thanks TT members.

Thanks, I looked through the jetting database already. I did not see anything that matched stock + Dr. D on an '08. Apologies if I missed it. Just wondering if anyone had any specific feedback on this particular set up.

stock pilot, 165 main, needle on 4th clip position. That info is direct from Doug Dubach himself.
