I had a plug foul on cyl. 3 so I replaced all my plugs. I have driven around 100 miles and I tried to start my bike for the first time of the year and it didn't want to. I finally got it started but it wasn't running right. It was running just on 2 cylinders. 2 of my 100mile plugs wasn't fireing. I put 2 of my used plugs back in and they fire great. The plugs look a little black but not excessive. Can carb cause these plugs to foul out? this is on a 80 1000ltd
Do you think I got some bad ngk plugs?
Would also check ---
Voltage reaching coils;
Spark quality on plugs (remove each and visually inspect spark);
Compression and valve clearances;
Fuel level (clear tube test);
Clean air filter;
Nothing under seat obstructing air intake.
Good Fortune!

I just checked voltage at the coil. I have 11.31 volts at both coils. I have 12.33 volts at battery. I lost 1 volt. It that enough for my problem? I am going to go ahead and track down where I am lossing that 1 volt. I checked at kill switch and have 11.31 also. Now I am going towards the ignition switch.
i would be very surprised if the minimal voltage increase
solved the problem....sounds like a carb problem...i get less than 11.3 at the coils and my bike starts within 2 secs cold and the plugs look good.....let us know how you make out.....

Is this voltage a problem? I also checked my compression cold.
150,110,115,130
I then put oil in cylinder.
240,200,175,210
So this just about doubled my compression. I presume this means a tired motor.
Do I need a rebuild motor? Do I have 2 problems? Think I could just rering?
