I think yours is a V2. I have one on my bike. I bought it used from MPH Floggers corner about 15 years ago. I use kevlar plates from Barnett. They also fit some Kawasakis and Harleys. The inside of my primary is cut away so that the clutch runs wet with the primary chain. I run it wet, often in ATF but sometimes I use regular motorcycle oil. I only use four of the 6 springs because I find that gives lots of grip, but three springs wasn't enough. You will need more lift than the standard mechanism gives. I use a lever with 1 1/8" centers instead of the original 7/8" type. Also I have a mushroom shaped adjuster that moves the lower pivot point of the arm further out. It works great. If it grabs and squeals it means I have to top up the oil in my primary. I put a bit more oil in the primary than is normal.
