Cam lam 6 plate clutch

Postby Scooterdude » Fri Feb 08, 2019 9:55 am

Still looking at options for a new clutch. Been slightly put off the AF cassette after reading the mixed reports on them, MB 6 plate just shy of £500 now so not an option, Readspeed 6 plate £350 a bit more bearable but just found the cam lam 6 plate at £270 looks very much like the Readspeed, anyone using one and any good?

Can only speak of my experience of AF clutch.
Nice and light, but with feel.
Well made.
Fitted it and forgot about it !

Due to an involvement in racing, I believe the CamLam clutches evolved to their present state, principally to support Charlie Edmonds. He has not raced for some years now.

When they first appeared, being manufactured specifically thin with the friction plates as well as the steel plates, it was possible to fit nine friction plates in the space of an extended clutch of Lambretta, generic design.

However, racing is all about ragging the best from an engine & the thinner plates utilised would have badly burred edges after one meeting & require extensive tidying or replacement. That certainly was my experience, & in the case of trying to run nine plates, with virtually insufficient space for the plates to 'clear' when cold, it was all too easy to break teeth on first gear upon start up. (Hence, the last racer I built has a modified, alloy six plate clutch of my own design)

That said about CamLam clutches, & to use up NOS, I have fitted five & six plate versions in road going bikes ridden by the odd nutter, & they have been fine.

To add a little more information that may help your decision, I have personally used the ScootRS six plate clutch & that has also coped easily in a fairly torquey Rapido 240 plus that pulls GT200 top gear. Sadly, I believe they are no longer available.

I can't recall whose clutches the racers from RLC used, but they rated them highly......

I hope that helps :)

I have 2 AF Cassettes (TS1 & Rapido) and 1 LTH 7 plate in a 283. All 3 have been fit and forget and work out of the box.

My earlier response was with the view of how to enable a stronger clutch on a budget, & if there are no financial constraints, there are undoubtedly 'fit & forget' clutches derived from motorcycles.

If money is tight, then a clutch can be done on the cheap that can work very well.

The old, two part, 46 clutch sprocket can be disassembled to enable the clutch ears to be depressed fully. Reassembly is best done with high tensile, button head socket screws (M5 I think) in the existing, ex rivet, holes tapping into the main sprocket body. I've done several like that, though 46 - 49 tooth sprockets are obtainable ready with deep pockets for the fitting of additional plates. Again, I have used them in conversions & they have been fine. I prefer to aim to fit six plates but five, in conjunction with good springs, can work well, say in a TS1. If modifications are to be made, you may as well try & fit the most plates that don't cause drag.

Inner clutch bells are obtainable designed specifically for more plates, & it is worth shopping around.

I hope that helps a little more, as not all of us can justify substantial funds & I am aware that the excuse of "only cost a tenner" cannot always fool the other halves..... ;)
