Okay, I was up till midnight but I got the new pilot jet in there. Drastic improvement, but I'm still not there yet. I have what is probably a silly question. Will it backfire if I've turned the idle mixture screw out too far just like it will if it's not out far enough? I know that I'm looking for the sweet spot combination between the idle speed and the idle mixture but I'm not sure what direction to go?
Yes I've read Lancer's tuning guide and LOTS of other threads on tuning the carb, but I'm still having a little trouble getting it. I write computer software all week long and it's probably the only thing in the world that I do well. I've come a looooong way in the past few months but I'm still in the Motorcycle Maintenance for Dummies category. ha

There are two main things that can cuase back fire. Lean fuel air mixture and a leaking exhaust. It seems you have been concentrating on the mixture .
To check for exhaust leaks, get a candle, light it and hold the flame up to all the exhaust joints with engine running. The flame should not be moved, either blown away from or pulled into the joint.
It could get pulled into the joint because of ..... (see me scratching head again) venturi effect or is it Bernoulli's principle..... . Anyway, a leak will introduce air where is shouldn't be and the results can be a backfire also.
Check for the leak then get back to us.......

You're right, I have concentrated almost entirely on the mixture. We had to remove the exhaust to put on the new muffler so we certainly could have sprung a leak. Rain this afternoon so I'll have to check it tonight or tomorrow. Hopefully I won't blow myself up with that candle next to the exhaust.

Well you were right. I had an exhaust leak. When we installed the new pipe we snugged the head pipe while we got the muffler situated. Yep, we forgot to tighten the head pipe.
Unbelievable! Oh well, I openly admit what a moron I am. After fixing the #@%$ exhaust leak, I used Lancer's tuning guide and now I'm dialed in. I still get some burbling & crackling on sharp decelarations using the engine, but from what I've read that's normal. Thanks for the tip(s)!

Good Job finding it! and welcome to the moron club - my best one (I think
) was when I changed out the leaking head plug on the '95 and kinked the head breather tube put'n it back on - full twist smooth cutoff any air out of the head - well this ran the crankcase PSI up enough to push oil up the speed-o-meter cable to the speed-o-meter itself and leak back down the spring coil - covering me and anything behind me with oil - yehaaaaaa
oh but we should really have a moron hall of fame - while yours is goofy, and mine was just dam dumb -
how about this pair from a couple of esteemed members (who shall go unnamed by me
)
one was running a grinder next to a battery and blew it clean up - the other changed the oil and didn't put any back! - so relax there's better morons around!

The exploding battery would have been the end of my diy days! I take moments like that as road signs down the highway of life. When I'm out riding and I nearly wreck or lay it down (or are run off the road by somebody on a cell phone!), I turn around and head home. I say to myself, "Yep, almost died. Let's go home."
