Need some help with clutch sizes

[xtirex]

Hello,

So i just have a quick question.
I still have an original longjia grido clutch, i think the size of the bell is 112mm (not 100% sure).
But if i now try to put an 107mm clutch, will this be a problem..? Or can a 107mm clutch work normaly with bigger clutch bell?

I'm thinking about buying this clutch www.scooter-attack.com/motoforce-clutch-racing-pro-adjustable-d-107mm-minarelli-piaggio-peugeot-honda-mf80-107-39.html (is it even better than stock?) (+ i will buy hard contra spring from stage6 - www.cilinder.si/scooter-50ccm-2t/minarelli-horizontal/sklopke/povratna-vzmet-stage6-minarelli-trda.html )

I really don't like my stock setup because scooter starts moving at 3000rpm and its really not fun at all
Soo.. any advices?

And thanks for all replyes and help + i'm sorry about my bad english.. not my first language .

My setup right now is:
cylinder: Stage6 RACING 70cc
Crankshaft: Motoforce Evolution Racing 
Exhaust: Yasuni C16
Carburetor: Dellorto 19 PHBG
Variator: Malossi Multivar 2000
Reed Valve: Malossi MHR

You can use a clutch of a different size, but you'd need to get a matching pair of clutch and bell. You can't put a 107mm clutch inside of a 112mm bell. Well, I guess you can, but it won't work very well. So, get a 107mm clutch and 107mm bell or just get a clutch to match the size of your current bell.

I've never used that Motoforce clutch, but I had an MRP that looked just like it. Actually 2. The first one broke in short order on a mild/sport 70cc. The second was some other branding, but seemed the same as the first... other than it didn't break a shoe off quickly. They got the revs up more than stock for me, but I never used them much because the higher engagement and increased slip that I had made the stock clutches more appealing to me. I've never owned any of the more expensive clutches to tell you much about them or how these budget sport clutches compare.

I'd say don't buy that clutch. Cheap. If it broke on a mild 70cc setup, I expect it not to be reliable on a 70cc Racing cylinder. Get a Malossi Delta or a Stage6 Torque Control clutch...

Hmm.. okay.. thanks for all info. Didn't know you couldn't use a smaller clutch in bigger bell.. hah.. but yeah its logical. Will take a little more time and put some more money on the side so i can buy stage6 or malossi one.
Thanks again both of you guys.
btw 90GTVert love your videos on yt!

I'm a fan of the Malossi Delta if for no other reason it makes swapping clutch springs so much easier.
