Was I running rich?
So I finally got around to buying a pipe and jet kit. I took the bike apart today and jumped into the carb for the first time. Looks like i was running a #132 main jet this whole time. When I bought it last year the PO said he installed a K&N air filter with air box lid removed but never mentioned jetting it. The bike always seemed to run strong...
I think I'm gonna go with the #128 main since thats what dynojet suggests and I've seen that size around here quite a bit
Any comments? suggestions?

Or maybe he did, as the bike always seemed to run good. The 132 was probably not a DJ132. My 250 would run with the DJ132 just smelled really rich out the back end. DJ128 works great with aftermarket pipe. Even without a pipe no airbox lid and a K&N will require more fuel.

Bike can run well and still be really rich.... I thought my bike ran good before i rejetted it for CO. Then i didnt touch the jetting when i came back and took it for a ride and it ran better. I think i had it a bit too rich and when i tweaked it, i got it spot on.

I'd be worried if I found sealant in there... might be a good idea to clean the surfaces and just install a new diaphragm. You don't know if the PO drilled it or not... My '09 DynoJet kit came with a new spring, and did NOT tell me to drill the hole in the diaphragm.

Anytime I have a bike that runs well at all rpms and I want badly to have a problem to fix jetting would be thet last thing to come to mind for me. My KLX is a little fat on either the needle or the main but runs and pulls as good as I could ever expect it to so I'm not real concerned over it and have lost no sleep over the issue.
