The bike I bought has a Pit Bull damper on it, which covers the top triple nut. I don't know how I missed it, but the top triple nut is missing! I've raced it like this for 3 weekends at least. Because of the Pit Bull damper, will the stock top triple nut work? I believe it's an acorn style nut. Does anyone have one they can sell me or send me in the right direction? Thanks!
