Yes, you have to send the scatter shield in and have the window.

That's one of the disadvantages of the sintered iron disc. It needs to be adjusted. You also really need an adjustable pressure plate. When I stated using mine, I couldn't buy an adjustable plate, so I'd make 6-8 hard runs, pull the clutch and take it to a local friction house and have the pressure dropped.


I started at 1200 and ended up at 660 pounds with no counter weight.

I can't imagine needing 1800 pounds. Sounds like a parts breaker.

I update my clutch a few years ago. I now have an adjustable PP. On the street I use about 950 pounds of base and about 12 grams of CW to keep it from slipping. At the track, depending on conditions I start at about 500 and 10 grams of base and work from there.
