Fouling plugs again

I replaced all the plugs last fall. Fouled them again. Replaced FPR and plugs ran great for 2 months. Then again today misfiring. At a loss.

make sure your oil lever on the corrcect lever,oil lever too high will wet the ignition plugs,and then dirty the plugs and hard to fire.....

A new regulator or a secondhand one?

Did you confirm the previous regulator had failed?
Have you checked if this one has?

Re: Fouling plugs again

when i checked the plugs they are all black. Exhaust also has black on the tip. Is bike running too rich? The bike has a 1/2 Yosh system and previously had a 1/2 Ti-force.

How many mpg are you getting?
Are you running a PC?
What do 3/5 and 3/4 mean?

Re: Fouling plugs again

Dont feel bad my gas light turns on when i have a full tank of gas. so i just watch my mpg. @ 140 i fill up at the most i normally do it at 100 just to be on the safe side And the thing about your plugs being black. I have herd that the moment that new plugs are put in and the bike turns on there black. Because of Fire! BUt yeah do you have a pc. make sure that you have the correct map i believe that its # 14

If they're black then you're either burning oil or running way too rich.
I've pulled plugs out of engines after 30,000kms and they're a beautiful tan colour as they should be.

No PC. I got the bike last Aug. meant to do a oil change and never got around to it. I didn't ride alot. Could old oil do it?

If the oil is old or the wrong viscosity it will bypass the rings to be burned. Is it using any oil or blowing any smoke?
How many miles are on the oil now?
