Problem with Plugs.

I am having a problem. I burn through spark plugs like a baby burns through diapers. Every week or 2 I am fouling plugs. buy a new set, and another week or so and they are fouled. Bike runs great, but when the plugs start getting black bike runs like shit and backfires. What can I do to fix this problem? Carb adjustment?

black means too rich of mixture.
Sven will be along to tell you about float, idle jet, intermediate jet, main jet,
mixture screw, air cleaner, heat range of plugs and other causes.
Also maybe even tell you about the enrichener valve...
Your job is to read and understand what he says..

There are a lot of threads on carb adjustment and repair. Use the search option at the top right hand corner of you're screen.

Don't forget to check the ignition system I went through the same thing. plug's every week hard to start the old Thunderheart just didn't cut it. MSD ignition in same plugs two years. just a thought but it worked for me.

I would like more information on the MSD ignition set up that you have... Like model number and where you purchased it?
