Modded CRF150F Jetting

Recommended Posts

Guys i'm looking for some jetting info for on a 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 45 and 48 Pilot on hand, but it may richen it too much. I also have a 125 and130MJ 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

Thats a good idea, haven't thought about checking the plug.

Do you check the plug on a 4 stroke like a 2 stroke? I know about the electrode color i'm looking for, but is it a plug chop? Ride it about fourth gear WOT and kill the bike while its wide open?

If so, this only checks the main jet, correct?

Anyone?

I put a 45 pilot and 125mj in it. Seems to cut out when running WOT. Pretty sure that the mj is still too lean?
