hello i had to take my rev 500ss in for service because it kept fouling plugs about every 20 miles (pretty expensive plugs at that) and after aboput 3 sets of them i decided to take it in and see whats up well it appears i have a blown crank seal. now my question is would that make plugs foul out? it was the clutch side seal that blew and it was the clutch side plug that kept fouling (i think). should i have them look further into it? maybe check the carbs?
