Modded CRF150F Jetting
Posted: Thu Mar 19, 2009 1:32 am
Guys i'm looking for some jetting info for my gf's 04' CRF150F.
I've changed it to a 42 pilot, 115 Main, 4th clip on the needle.
Before i rejetted it, we added a big gun pipe, pull the air box snorkel off, and added a Ready Filter.
Bike would bog bad enough to kill it right off idle, and was getting extremely hot (i think, not too familiar with the 150's). I knew it was lean.
Added the 42pj, 115mj, and changed the needle and it runs great. I'm still wondering if it runs a little hot though.
How can you tell if a air cooled bike is over heating?
I have a 48 Pilot on hand, but it may richen it too much. I also have a 130MJ on hand, but wondering if its too rich also. I'd rather it run rich and run nice and cool though.
So what do yall recommend? We ride anywhere from 0 to 1000ft above sea level.
The only mods to the bike are the big gun head pipe and muffler, air box snorkel removed, and a higher flowing filter.
Thanks
