Initial start after rebuild --- Problems....FIXED 4-22-11!!!
Just got the rebuild done on my 77xs. Installed pamco ignition, dual coils, new pistons, rebuild head, all new gaskets, and carbs rebuilt by old school carbs.
When kick started bike cranked in less that 10 kicks. Ran on choke. And when taken of choke would idle down. However on the right side cylinder sounded like it was mis-firing as you could hear it through the exhaust. The intake would also spit/pop fuel out.
Checked:
Swapped plugs- no change
Swapped wires- no change
Checked compression- same on each
Checked valve lash- good
Cam chain tension- good
Cam Position- good
Timing- good
Intake boots- OK
Carbs- Appear OK
The right plug doesn't appear to have soot or fuel. What's weird is the bike will idle and doesn't appear to run awful. Just the off sound at the exhaust and spit at the intake.
Any ideas? Right now I'm thinking carbs but the idle appears to change when mix screw is adjusted.
