Well, the weather cleared but my head didn't.
I've been sick as a dog for a week. Missed two days of work.
I swapped the jets for 40 pilots and 98 mains. I installed a new aftermarket air filter (I just got a used UNI drop in filter in the mail today. I have some genuine UNI foam and I'm working on replacing it now).
The bike
seems to run a little better in the low and mid range, but I can tell it's still not right. I still get a bit of a hanging idle effect at times. I
DID manage to get the mixture screws out to about 1.5 turns, which is where they're supposed to be. That seemed to add some smoothness.
It cranks immediately, requires little or no choke, but is slow to warm up to where it will idle on it's own. No popping, burbling, snapping, etc., that I can hear anywhere in the rev range. Either from the carbs or the exhaust.
I've checked for air leaks and found none. I checked to make sure the advancer snaps back and it does. The springs are on the posts like they're supposed to be. I checked timing with a new light and both 1/4 and 2/3 are dead on at advance.
I'm wondering if I have weak springs and the advance is maybe sticking at times? I also need to try the clear tube method and check fuel level. Those are the only other things I can think of that would cause idle issues.
And there's still a chance there's some electrical oddity going on.
Pulled the #4 plug...not after a chop or anything, just after messing around with the bike....and it's still definitely rich. I can see a little color on the porcelain, but it's also black and sooty around the electrode.
At the very least, I don't feel bad about putting a few more break in miles on it like that. No chance of holing a piston or anything that way!
I still plan on getting it to the dyno. Maybe that will reveal something, too.
