The bike is a 916SP and has a slipper clutch fitted. Make unknown Can any one tell me if this can be adjusted out or whether the clutch needs replacing. If it does need changing can it be done by a mechanical imbacile, such as me, or should I take it to the garage. Only probelm with the latter idea is they are booked solid until July. Also any idea of price and where to get it from. thanks Kevin  | |

What I have found is that some plates wear more than others, which seems a bit odd, but does seem to be the case. Assuming you have a 6 post slipper, it's pretty easy, remove clutch cover, then set about removing the 6 pressure plate bolts, and keep hold of bolts, springs, and caps. No pull the pressure plate off, this may take a bit of force, now you will see the firction and steel plates, remove plates one by one, obviously remembering which order they were removed in, and if possible keeping them in the same position, you will notice on the steel plates there is a notch cut out on the outer edge, keep them line up across the clutch pack. After a couple of plates, you'll begin to struggle getting them out as they go further into the clutch housing, I use a wire coat hanger I've cut down to pull the plates where your fingers can't reach. Now when all the plates are out, clean out the clutch, an air line is good, but if you're like me you don't have one. Now I have in the past reversed the friction plate order, and extended the life of a clutch for about a 1000 miles, but a slipper clutch from my experience of having one on my 996 eats plates in comparison to the standard clutch. As soon as you're off the throttle the plates are slipping, increasing wear, which unless you're doing track days and not ride on the road you will be OK, but for me on the road they eat plates. Anyway... I digress  Basically Get somew new plates, and rebuild in reverse to the removal... It will probably take just over an hour your first time. | |

| Hi Kevin, I doubt anyone will recommend this, but.... My old Pantah used to slip it's clutch every 6 months or so due to the springs being too weak (alloy clutch to brittle for stronger springs). What I did was take all the plates out and wipe them with 400 enery paper. Just enough to take the shine off them, then pop them back in & off I'd go for the next 6 months. If your going to get a new set of plates, then it might be worth trying this on your old plates 1st. Jim ...oh,oh,.. here come the responses... | |
