[Gizmo]

Fitted a S/H slipper a couple of weeks ago and the spider spring that came with it was almost flat, stuck a new one in and now 2 weeks later the clutch is slipping and the spring looks like its not pushing plates and has flattened again anyone got any idea what can cause the spider spring to flatten so quickly??

Im on my third..........i think they are fairly weak. I see the 4 post clutch gets a bigger spring!

[chillo]

i've had 3 fail on me, they just seem to crack and break up!
Absolute shite if you ask me, especially as they are £40 each time

Is there a heavy duty/race spec replacement available which might be a bit more durable?

When you said it was going I didn't realise it was that bad or I would have left you another one.

I get through them all the time and I am sure there must be a cheaper and better alternative.

As has been said there are really strong ones, but from what I gather they make it pretty heavy gong on the clutch action.

[Gizmo]

oops, sounds like this could be coming out quite quickly, 2 weeks of road riding and its fooked?? not much use given the mileage and use I give my bike

[Gizmo]

it was bad Lil, struggled to get up hartside tonight had some interesting moments when the rear wheel caught up with the slip over the crests It'll be that Martin H playing on his way back down the lake on Saturday afternoon, knew I shouldn't have swapped bikes , sorry don't mean it Martin

[Lily]

the other option is to do what I do and live with comedy clutch when it starts to go..

Makes roundabouts and junctions mildly interesting, but you get used to the whine and the slip after a while..

Are you guys sure you are fitting it correctley? I've had mine now nearly three years and only changed the spring because I ferked it up trying to get it off the 748.

I had my earplugs in Michael when you gave me your bike and thought you said "See if you can WHEELIE it back to the house" Sorry I now realise you had said "Take it REALLY easy back to the house"

I agree with Jon, here. They should last quite a long time. One clue is how much you need to compress them when you install the centre nut. It should only compress a couple of millimeters, and nowhere near "flat". Also, the spider spring doesn't affect the heaviness of the clutch or clutch slip when accelerating. That's controlled by the standard clutch springs. If the spider spring is worn out, you'd simply get excessive clutch slip when decelerating.
