Hey everyone, New to the Forum. Please help. I have a 1994 Suzuki RF600R that seems to limit me from exceeding 100mph. The motor seems to pulse when I reach 100mph. I've been reading about this bike and it says that it should be a 150mph stock. The bike has 8000 miles on it, I purchased it last week off a young woman that baught it new. But I did not know it was doing this until I had it home.
