Cassette clutch plate Surflex option

Hi guys I'm after some clutch help please.
At Easter I fitted a 6 plate cassette clutch made by a very reputable dealer. Said clutch was sold as to be good for up to 24bhp which mine is below at 23. It's slipping when reaching high revs and probably has done from new which I have mistaken for characteristics of a new cylinder kit that I was getting used to at the same time.
I know to contact the dealer will prove pointless.
I've become aware that better clutch corks are available made by Surflex, can anyone tell me who might sell these or if there's a cross over to a motor bike etc that uses them or a part number? The clutch is the lesser to it's Python equivalent.
Thanks for any help.
P. S I don't really want to spend at the dealership where I bought these as I feel it's not really as all that they claim.
Thanks

Think the dealer should be first call as they would know exactly what’s inside the clutch

Why would contacting the dealer be pointless? If it’s the maker of the clutch then I think they would be very helpful as I have had problems resolved in the past.

Thank you for your input, but my thoughts are that way because of how things generally are in this hobby, interest, passion we share, expensive parts that often fall short of their intended use with no come backs once fitted and sometimes once removed from the bag. So I thought I'd just save my sweed from any further disappointment.
So if I may go back to my initial question can you offer me any help on that please?
I'm just after a simple hassle free solution.
Thank you again

A couple of months back I bought a new six plate cassette clutch - all was well then lots of clutch slipping
adjust cable, fine for a while then lots of clutch slipping

In the end took the clutch out to find out what was going on and found the 6 Allen screws were not tight
I think what was happening - adjust the clutch all was well, use the scoot, clutch holding together screws unwind a bit, clutch goes out of adjustment and slips, repeat over and over

Finally - tightened the cassette clutch holding together screws using loctite, been faultless since - went to Brittany recently never let me down

Never had to do this with the 1st, same make clutch, but had to with this new batch

Thanks for the heads up on those Allen screws, I'll be sure to check on them when I'm in there in the very near future. It would be re assuring if the cure is this simple 8-) 8-)

I would really appreciate any help on this fellas please. This kind of clutch has been doing the rounds for a few years now so surely someone has found better plates etc?
I have done a search on here so please don't think i'm just doing the easy thing by asking without trying. To get these plates, springs etc from a source other than a scooter dealer isn't un heard of.
Thanks

Hi Thackers

So are you saying you don’t want to buy from any dealer in the UK?

I fitted a cassette clutch some time ago and initially had some issues, but spoke with Ben @ AF, which I must say he was extremely helpful, we had a crack and he gave me a few pointers, I cleaned up the steels fitted new plates and things were as they should be.

Btw, I bought fresh plates from Chiggy @ Lambretta upgrades another excellent dealer imho.

I hope that helps

Good luck with resolving your issue.

Hi and thanks for your reply. No i'm quite happy to buy in the U,K I'm really wanting to by pass scooter dealers and their probable high cost for something a motorbike parts shop will stock at a lower price possibly. I'm just a little weary of buying parts that don't seem to to be fit for purpose or need adjusting to fit. Then to find out better internal parts exist in shop! Which indicates to me the awareness of problems that lie within. Why are these parts not fitted as standard?
You say you encountered problems and then had to buy better parts, fettling along the way to get the item as it should be. It shouldn't have to be this way. Like i've said i'm just after keeping my head from it's fight with it's thought's.
Thank you for the Lambretta Upgrades suggestion and wishes of a good outcome.
