I put a Radio Shack rectifier together and got the VR291 (AMC/Jeep) regulator that doesn't require the brushes to be insulated. Seems to be charging just right. Now it's been a little chilly to ride here and she sure doesn't like to start in these sub-30's we've been having.
I'm still having a little oil weeping from what looks like the head gasket, specifically the left hand side right under the spark plug. I put the torque wrench on the acorn nuts and got a little movement out of em. It still has the steel/rubber washers on the outside so I'm gonna try replacing those with some copper ones and see if that fixes it. If not I think it'll be time for a set of gaskets

I haven't ordered up the head gasket or washers yet but I've been doin some riding and after wrapping it up a little it started to backfire pretty bad. I popped the filters off and it looks like I got the carbs pretty far out of sync at some point. I bumped the idle up a few days ago and must have missed a turn on one side. Pulled the plugs while I had it apart and they were pretty sooty (picture). Buttoned it up and it still doesn't want to rev up smooth. When I got it warm it started to idle up and I had to hold the brake and let out some clutch to pull the idle back down.
Could this be a symptom of that head gasket leanin the mixture out or should I try bumping my main jets up?

Here's what I heard in that post:
??? So, does that mean you put the fouled plugs back in there?
If those plugs are dry/sooty, it may be running too rich already...

Fair evaluation. I didn't have a chance to get new plugs so I cleaned them up a little and put them back. The reference to bumping up the mains was because of the popping and backfiring with throttle. I was thinking the sooty plugs could have been from the warmup with the enrichener/ choke on
