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.

Not much there yet for the '08. DRD doesn't have it up on his site yet, either. I would just start playing with it. Try a 165 main and see where that goes. Todd's set up is well thought out, and may work well for you.

Look this over:

Thanks gray...yeah, I tried Dr.D's site but nothing for '08 yet. I will try 165 and report back.

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