Hi, I'm selling my 50 special to a mate of mines missus, at the moment it has a dragtastic 4 plate in there with an uprated spring which will be a bit much for her girly hands.
If I wanted to change it back to standard would the a standard 3 plate clutch fit ok and work in the 4 plate clutch basket?
Also, would I need the 3 plate corks and matching steels (I was under the impression the steels were slightly thicker in a 3 plate clutch than a 4?)
Cheers, Rog

Yeah,3 plate should drop straight in. Alternatively you could convert it to a 3.5 plate by binning a steel and scraping the cork off one side of a plate.

I imagine lots of heat build up, but someone should just test it.

Remove one steel...that would leave cork on cork. Now scrape the cork off one side of the cork plate, leaving just the steel.. Never tried it myself, but it should work.

so then you will have a 3 plate with 2 thin and one fat cork as the two would be linked in the outer basket. why not use a 3 plate. ;D
I was thinking about removing the cork from top or bottom plate. maybe i should stop thinking ;D

Hang on a minute I've tried this but I've just had a thought..... If you lose the steel, then clean one side of one of the plate..... Ok it will be steel cork steel cork etc. OK lets think about basics, the steels are interlocked with your centre clutch, the plates are into locked with the outer basket. The clutch springs push all the compnents together thus power to the back wheel. Pull the clutch in springs compressed plates and steels part and are able to spin. But surely the two plates side by side (without the steel) only act as a thick plate (both interlocked to the basket) and actually have no effect on the suface area used to maintain the power getting to the back wheel. e.g more plates=more surface area to hold onto ya horses.... Just taken me three hours to type this and I see Unreliable has beat me too it ;D

I was always thinking about top or bottom plate, not just binning a cork in the middle of the stack, until guy explained it. I guess that degree of mine must be good for something after all.... ;D Thats the dream af a 3.5 plate crushed for hank and juan then ;D

Ok, so what is the advantage of 4 plates over 3?? Or is what we are saying is that the 4 plate are a waste of time!?!
Ad, What was it you say you run in the parma?? And what is every one else using on 16Hp'ish scoots??

You lot and your 3.5 plate clutches! So the steels in a 4 plate are the same size as a 3 plate then?

i found 16bhp rw pwr is the most a 4 plate with malossi spring can handle with normal corks. Even then it struggles. Some put spacers in or one thicker steel. To be honest it doesnt help much.

I am curious as to what my options are for the clutch and speaking to Chiselspeed they recomend the zadra clutch kit... As I would, but don't seem to want to let onto any other options... I have a polini basket and have heard mention of ally plates and surflex plates.. Would these fit into the polini basket and would you go with 3 or 4 plate options in which variety??? Or would you just go with the Beedspeed 4 plate with strong spring??? Need to get something sorted as I don't believe that it is gonna handle the power as is, but obviously can't afford to go down the zadra kit route at the moment......
Cheers

i'd forget the beedspeed 4 plate with reinforced spring. no one says anything good about it. i guess the cheapest option is a std 3 plate with either polini or malossi spring. surflex plates are meant to be better and not much more money. not sure if that will be enough to handle the h.p. you're going to be getting. is that "super clutch" that terry sells cheaper than the zadra?
ad and tony will advise you better.

hi, it sort of depends on your gear kit.. steel or ally. If ally try this.. Xl2 4plate clutch from sip, 4 plate ally corks from Chiselspeed. Uprated (tho NOT worb5) springs from sip for this clutch. And if needed you can put cosa springs inside the uprated springs (or some others that fit better maybe). I currently have a 3 plate ally clutch using xl2 bits as above but it does slip a little with 20bhp.
Next solution-if steel basket just buy a 4 plate xl2 clutch from sip and if required fit springs inside the others.
Next step is to try different plate material. I know for a fact the falc plates are not cork but the have been modded slightly to fit the expensive but very nice looking falc clutch. Not sure what the zadra ones are tho. Might try some of these myself soon.
Adspeed has been playing with the xl2 and i'm sure he'll give some advice.
I personally think the single spring type clutches are not the way to go. I've seen them all to many times not compressing squarely.. So this must meen uneven pressure on the plates and maybe leading to problems such as dragging or slipping. Racing bike clutches use multi spring affairs. That says it all to me.
