Wet plugs

[bonesaw]

I' keep getting a mile or two up the road and my plugs fowl out.after playing with carbs for days im starting to think it's more of a timing issue or possible vavle adjustments.any insight helps.

Also might be an intermittent issue with the coil?

Some info:
I'm running 750 big bore/xs performance cam/new valves springs/keihin pwk flat slides 110 main 35 pilot--I've even leaned out the carbs but still same issue. Hughs pma/pamcos Hall effect.

This girl is making me earn it this year!!

I've never fooled with those carbs, but this simple test may help to narrow down the issue.

Install fresh/clean plugs.
Bring along your plug wrench.
Fire it up to do your ride. Just before taking off, turn OFF your petcock(s).
Do a short 1 mile ride.
Pull to the side, shut it off.
Pull the plugs, see if they're still wet.

If dry, probably a floats problem.
If wet, probably a jetting and/or filter and/or exhaust problem.

These aren't cast in stone, but it's a start...

yup. at least you would know wich end of the motor to start at. intake, or exhaust.
Im guessing floats out of spec.

With these new pwk flat sides running the correct way,I had to retard the advance.thank you very much guys,I hope someone else who has these problems finds this thread and a simple remedy. It's hard to have done so much work and the little stuff always get ya at the end!!
