i have a 88 polaris indy and the plugs foul often. I rode it on the lake and in 20 minutes i had to change the plugs twice and i checked the spark and it is only getting spark every once in a while. The sled runs really good when the plug gets sparka nd does not foul. Help is appreciatied a lot thanks

Could be a bad plug wire or end cap- change your end caps first and check your spark.

I had the same problem with my Indy 500's and found out like Ibreakstuff says, I had the incorrect plugs. I was running BR9's when I should had BR8's. Changed plugs & it was cured.
