What was wrong?

 

 

Dang Dude You have been around long enough to know better than to leave it at that "Great, I figured out what was wrong."

What was it

WP

 

Was your motor setup to 208 CCP? Cause after 25k on the build I would think that carbon is building......

I'm thinking he found a bad plug wire.......

 

Please, complete the thread with how you fixed it. We would like to know. Thanks

 

My engine had 200+ compression when built. 10-1 weiscos, shaved heads, .030 cometics HG.
I already changed plugs and wires as stated earlier. Got to go back to work right now.

 

Back home from work and went for a ride and as the engine warmed up the problem came back. The new ignition and coil did not fix it. Anyone have an idea?

 

As engine warm up, Miss fire at idle and rear exhaust makes a fluff sound and wont idle.
Spark plugs are perfect color and I also changed them and the wires.
Yes, no intake leaks with carb cleaner.
Its S&S carb and I dropped the bowl and pulled the jets, all is well.
new Ignition & coil is installed.
Regulator is good.

Sorry missed the wires change....

Have you checked the ignition rotor on the cam to see if maybe it loosened up a little.

What about the cam sensor, any goo leaking out?
