Clutch Re-Build

About to do my first clutch re-build, (hopefully after going to Power O this Saturday) I plan on replacing all drive (fibre) and driven (steel) plates, as well as both bearings, springs, washers, clips etc.

And was wondering what all of those who have done this job. Think about the options are in regards to the plate options, genuine Suzuki or aftermarket Kevlar or aftermarket fibre ?

Could save about $100 with the aftermarket, but more interested to know if anyone has comments good, bad or otherwise to their experiences ?

Cheers

Hi Paul
I've only done it once and used OEM driven plates and generic aftermarket fibre ( nothing special - but I only have a 750 ).

Only advise I have is be sure to replace the clutch release bearing and washer ( I also replaced the shaft bearings ). If your going to do the clutch why not do everything and save a gasket later.

When I stripped mine, the release bearing was missing a couple of needles :eek:
 
No worries Toad, Stuart, depending what I find when I open her up, was planning on replacing everything except the primary, sleeve and pressure plate.

I think the A.P.E gear is good quality, might give the GS Zone option a go :D

See Saturday Glen.

Cheers

I had to do it on the GSXR and considered the aftermarket but read bad stuff so I stuck with OEM.
It's not to say that it won't be alright but for the extra $100, you know it'll do another umpteen thousand kilometres.
 
Cheers Murf, I see their fibre plates are 1/3 of the price of originals !! :D, can these be used with the standard Suzi steel plates ?

On a stock-ish motor, any fibre plates would do (OEM/Aftermarket), there comes a problem when you go up in the power, the stock clutch will slip.

My motor has somewhat a bit more urge than stock and I have big issues with a slipping clutch, the easy way to fix that is with a lockup clutch which I have had on mine but only on loan from Joe.

When I got my current kat, I replaced the fibres and springs with aftermarket which was fine when it was a mild 1260, add 36mm slingshot carbies, 1360 kit and cams, aftermarket is not enough.

The Springs I got were heavy springs which gave more pressure but that in itself is still not enough, I then added another steel to preload the springs a bit more, but still not enough, at this stage it was getting 11.003s quarter mile times... with a slipping clutch and since my gearing was set high (270kph@9500), it was not east to launch off the line with 2.1s 60 foot times!!!

Another way to get a better clutch is to use the later model 'Extra Plate' setup but since my fundage has dried up, not an option for me, so....

Joe has always said that stock kat fibre plates are fine so I decided to do some measuring, I measured the area of the fibre plates that actually touch the steels and found that the aftermarket fibres had less area than the stock Suzuki fibres and thus, if I used stock fibres, there should be less slippage as there is more area to grip on.

I gave it a bit of a test yesterday, with a bit of throttle applied and shifting into 3rd, the front lifts and carries with no slippage, with that and now with lower gearing, it is an easy 10s kat.

If your stock fibres are not worn too much and not contaminated with 'oil additives' they will be fine.
