Jetting Question?

Hey everyone, I've got an '07 750 Brute with MIMB snorks, Pro Circuit exhaust, and jetted carbs. The bike is running pretty rich ( I can smell it pretty good ). I *think* I ended up putting in 138/142 jets and the new spring. I wasn't able to adjust the mixture screw because of the cap on the 07's and I couldn't drill it out. I also have the 2" intake snorkle. Do you think I should swap to the 3" intake snorkle, or will that make the bike run richer? Thanks in advance!

Runnin bigger snorks might fix yer prob. Wont know till you try it. I'd drill those plugs for yer idle mixture screws. Those things are so stupid. **** EPA!

I would run the 3 inch. More airflow would lean it out. May not have to end up rejetting. For drilling out your plugs take a small drill bit & drill just enough to make a hole in the plug. Then take a small screwdriver or awl & pry out the plug. Its not that hard just gotta be careful.

Does anyone have a link for the 3" intake snorkle "how-to?"
