Okay, Big Joe went over it.
Moved a needle, advanced the timing, chewed me out about using enough oil on the air filter.
Repacked exhaust, put new o-rings in the exhaust sections, welded the busted bracket.
New throttle assy, new rear fender -- just cleaning up.
Put more oil in the front forks, so they ride a little higher -- today they felt a little stiff but showed much less inclination to tuck.
Took it down to Brian at the machine shop -- the flywheel on this bike is six inches in diameter and six pounds! They turned off a half pound!
I rode it an hour in great terrain today, 5500', cool weather. I think it's an honest Beta 250 again. Main impression is that it still spools up slower than I expect, and then tractors up the steps better than I expect. Very different dynamic than my GG280.
I finished the afternoon on the GG. Such different machines.
