I have spent most of this morning going over old threads in both message boards looking to get my head around the situation of clutch packs. The reason is that my 996sps is very rough pulling away, yesterday i sat on a 998bp for the first time and pulling away on it was no differant to a honda and very smooth.

I placed a post recently about the clutch slipping and gripping on take off and after removing the dished plates solved the problem. I am by the way running an aftermarket slipper clutch.

So my question to all you clever people is:
1) the friction plates look to have coppper based friction material. Are these god bad or normal, race or road plates.

2) the 998 runs 9 friction plates, the 996 8 friction plates, what is stopping me run a 998 clutch pack ( in the slipper clutch) and why the differance (engine output is about the same sps to 998bp).

and finally 3) a lot of people use ST4s alloy plates. are these a good idea, how many friction plates are used and what is the friction material/will it be smooth. Anyone using them in a slipper clutch.

I belive that there must be a definitve arrangement that will work for road use in most bikes as all dukes have the same crank cases. In one thread someone sugests cleaning the friction plates with wd40, surely thats like putting oil on your brakes.

Slipper clutches also have a bad name for bad pulling away but i don't belive there is any reason for this as torque is being apllied in the correct direction.

Any help with be greatly appreciated.

Many thanks
