Just bought an 03 WR450 and was excited to find this site. After a week of reading everything I could on here I'd like some opinions on setting up my bike. I've read all the info on jetting and what everyone else has but can't find one close enough to my atlitude, etc. Here's what I have; any info or help is greatly appreciated. Planning on an adjustable throttle screw and some new jets. Just not sure which ones.

The bike has the dreaded bog bad. I think the bike originally came out of MI. and never got rejetted for altitude.

Note: I'm at 8000 feet and will be riding between 8-10K feet. Temp: 65-80

Airbox opened up
Grey wire cut
Exhaust baffle out
Throttle stop done
Main jet 145 (don’t know where that came from)
Pilot 45
Starter 65
Leak 70
No adjustable throttle screw

Bike bogs bad and pops on decal.
Looking for help on jetting and any other mods that would help.

Check the jetting D-base. 3rd post down, Indy has a really good place to start.
