most likely both jets and emulsion tubes need cleaned in all the carbs.

Re: 1981 CB650c Won't Start

nice looking. But I'm biased as one of mine is just like that. If you have the auto fuel shut off still on the carbs ditch it.
Sounds like your starter clutch is going out too. Couple threads on it here.

Re: 1st gear only

under the clutch there is a spring that holds a couple linkages. It might have broke.

Re: no space between intake rocker arm and cam lobe to fit feeler gauge

as per the book 3 (and 2) is done at 2 diff rotations. In truth the Mark dont matter as long as your off the lobe. really?? Somehow I distrust that advice, from my experience small fractions of millimeters off can be disastrous. Distrust all you want. I"m a moron just trying to steer you wrong...

Re: Anyone have pods with an 82 Nighthawk 650(CV carbs/4 to 4 exhaust) ?

I did nothing it just worked. ran them first with stock 4-4 and then 4-1. ran good on the street. Then started drag racing it and dropped a few sizes in jets and got better. But I am at 5000 ft elevation.
