I think I am in trouble.....

Did you ever replace the spark plugs?

Two different set of carbs. Hard to think both sets would cause the same problem.

Charging system is upgraded and working very well.

Valves were done at the begining of the year. Sadly no where near enough time/millage on them to require another adjustment.


Three cylinders are firing one weak but firing.
Fuel tank was professionally sealed and the new carbs have yet to see the tank.

Hummmm well maybe I do owe you all an apology for not believing..... I would not believe this if I didn't see it myself, the plug looks good (not even discolored more than normal) but has no continuity to the electrode. I'll try it again once I double check my valves (already have the valve cover off).

What voltage do you have at the coils?

I'd remove the pilot jets and make sure they are open too. I can't tell you how many threads I've seen over the years where the person said the carbs were clean but they weren't.

I have two sets of carbs. This is the first time the second set have seen an engine since dip. Both sets were doing the same thing and if the plug is bad I guess that explains why....but now to figure out what made the plug go bad. It's a few weeks from a year old, it shouldn't be bad.
As for voltage at the coils I'm reading 12.4v at the coils. The bike has a new (every wire replaced) semi custom harness. I removed some dumb and added some of my own.
