Bike is back together, test driven, and is quietly resting in the garage.
Carb is holding fuel, the diaphragm was warn out and ripped/leaking.
Instead of taking the carb off, mostly cause it wouldn't budge - I just took off the bottom half - 4 screws and a c clip.
Replaced all the rubber parts (boot, diaphragm, small o-ring & housing gasket)and pump spring.
New tires are really nice, great roll to them.
Haven't done any cornering yet - I was warned to let them scrub off for at least 100 miles.
Smooth grippy feel though, did some slow speed slalom type turns.
New battery has a good kick to it, bike fires right up - it's new - it should.
Seems the bike likes the new oils - so far - finger crossed - at least its not hemorrhaging oil out of every seal.
NOW, I'm going to go out and ride the wheels off it... again!!
