Alrighty, So I got the #40 slow jets in from Sirius Consolidated. Put them in, as well as checked my accel pumps AGAIN (they are working). Turned the air screws out 1 and a half turns and.... SHE RUNS!! Although once I get on my bike to ride, it only runs good for about the first 5 minutes. It wants to stall if I give it anywhere from 1/4 to 1/2 throttle then it will just eventually just stall out. I'd wait a minute, start it up and drive it some more for a another 30 seconds before stalling again. Any suggestions?
So I'm concluding the bike runs awesome when cold. No choke, its like 80 degrees right now. But once the bike gets up to temp it wants to stall out.
Edit: My initial problem is solved. Before, the bike would stall with a little bit of throttle. That is now fixed.
EDIT: Okay I think I'm a half turn out to far on my air screw. I swear I read 1 and a half turns. O well, I will update tommorrow...
My 1978 is set up the same basically.
78 CB750k, Stock airbox, open 4-1 header, #35 slow, 120 main, havent been messing around with the air screw. But I'm positive the accel pump is working.
Except mine has a baffle type muffler.
Does yours have a muffler at all?
With a #42 idle jet it runs best with 3/4 turns out.
With the #40 idle jet I an guessing it will need 1-1/4 turns out or 1-1/2 turns if you can get away with it.
Please report back as soon as possible. I am very interested in your results.
I am wondering if the crossover between 1/4 and 3/4 throttle will be smooth enough with that #40 idle jet.
