Hi Guys
Bit of advise, am looking to replace the clutch in my TS1 and was wondering if anyone had any experience, good or bad, with the Rayspeed cassette type clutch unit

i have one in my ts1 the cheaper one had no problems since i fitted the gp side casing the thimble broke with a li side casing switched casings and no problems.i found that you don't want the cable overtight but top piece of kit

Thanks for that, what is the lever action like? The reason I am asking is, one of my mates has just fitted a cassette type clutch (not an AF one) and he has found he has to pull the lever right back to the handlebars to fully disengage the clutch, it doesn't cause him a problem now he has got used to it but he really struggled to start with

i have the cheaper road version on a 225 motor. done a couple of 200 mile rides ok. lever action is fairly mild for a 6 plate clutch. i was advised that this was suitable for someone like me who has little strength in their hands.
i still need to give it a test under heavy traffic conditions but ok so far

I use the road clutch on an imola and it works fine. You can have a lot more slack in the clutch lever as it works in a narrower band than a normal clutch

Sounds like the way to go, out of interest what is the difference between the road and race version about from the cost

race version features some cnc machined parts from what i know

One of our small crew has one and rode to Avignon and back and Davos and backand lots of other various places in between . Still going strong, the expensive one I think !

the difference in the 2 clutchs are that the basket one is cnc billet and the cheaper one is cast i find mine ok but not light but been told to use a Darrell Taylor clutch cable which would make it lighter.The only problem i've had is if you don't use the scooter at least every fortnight the scooter creeps a bit when setting off till the first half mile is done.

Hi Bob

I personally can't recommend the AF cassette clutch highly enough.

Accept they are £400, but I've now done over 15,000 miles using mine (I got one when they first came out). I've only just replaced the clutch plates after a recent engine rebuild (due to a piston circlip embedding itself into the piston, nothing to do with the clutch), and the plates really didn't need replacing, but as I have some new ones, and springs, I changed them.

Pulling the clutch lever in, isn't too much of a problem, about the same as my previous 5 plate. I use £6 nylon lined clutch cables, which helps.

I'll be building another engine over winter, and I'll be purchasing another AF race cassette clutch for that engine as well. (One less potential problem to worry about).

Of course, my opinion only, but based on hard riding miles over the last few years.

Well guys, thanks for the feedback, some very useful comments which have helped me decide this is the way I am going to go, once again cheers guys

I'll echo the above thoughts, I think theyre a great bit of kit.

I had no problems with the road version in my 23bhp rapido, however I have suffered some marginal slip but this was only at very high mileage.

The £400 race version is made by Surflex in Italy, the £230 road version is a copy of the race but made in India so the fit and finish is not as good. Take one of each out of the box and the Italian cassette will slide in and out of the crownwheel easily but I found it isn't the case with the Indian one, but 20 mins with a needle file smoothing edges will make it go together easier. Having said that I've got an Indian one in my sprint engine that went in straight out of the box and it works great. Nice easy action and coped well on it's only outing so far at Elvington where I did about 30 runs, slipping the clutch off the line at some decent revs. Everyone that tried the lever was amazed that the action was so nice, no firmer than a normal 4 plate imo. I can't recommend it highly enough.

Ended up fitting the AF road version and also replaced the chain tensioner for a pull down version whilst I was at it. Well made piece of kit, dead simple to fit, found setting up the cable tension trickier than with a standard clutch, but once that was done was really impressed with how it works. Previous clutch must have been slipping slightly all the time as it has transformed the feel of the ride completely

Hi lads just got the road one delivered can't figure out how to secure holding nut any advise cheers

Fit the holding tool and put a drop of loctite on the thread, then do up the nut. This is detailed on the instruction sheet that should have been supplied with the clutch.

Or jam a large screwdriver between the chain and clutch sprocket !

set the lever like you would a motorcycle, 6mm of slack at the lever works for me.
