Wondering what main jet people are running with WB slip-on or full system and vented air box lid.

 

I have a 99 400ex with the wb slip on muffler and drilled air box lid. I have run a 165 & 170 main jet. Both ran very good and the plug has burned clean for a year now. I got the jet kit from Dyno Jet and it came with the new needle along with jets ranging from 140-170. Hope this helps.

Thanks chet, btw, what altitude do you ride in ... i.e. I live and ride at sea level (south florida) and wondering if I should go a little richer

 

I live in south texas which ain't much above sea level so it should work fine. By the way were at in florida do you live? I have family in naples and I travel down there once in a while and am always looking for people and places to ride. You can drop me a line at bigtruck78@hotmail.com. Good luck to ya.

Chet,

I live in coconut creek FL (north of Ft. Lauderdale about 10 miles), and ride mostly at a local mx track http://www.aaconsult.com/airdania/index.html most trails around here have been run over by houses.
