Aren't all modern clutches pretty much the same? Bit of a hassle to fit the first time, but well worth it after that. I've worked with my own design, Falc, PLC, Hartz, in engineering terms the Hartz is the benchmark for me just now. The worst of the above was my own CNC clutch, btw.
Ill post a few pics of the plates next time Im in the cave ;D Ill also measure the diameter of them too, they do look like motorcycle plates. Clearance? Do you mean the clutch actually working when pressed in not dragging? Ive had the plates well seperating when compressing with the tool thats supplied and able to turn very easily etc. the clearance to cases seem fine etc. The only thing I can compare fitting it to is the xl2 clutch I put in my road scoot and seems just the same once fitted you know where you are with it lol

yes they are honda cr80 plates, about £35-40 a set and my local mx dealers/tuners recommended i use castrol power1 10w40 jaso ma2 or the silkolene equivalent
the hassle i had was of my own doing, i put locktite 270 on the torx screws that hold the top plate on, and when it came to undoing the cunts 1 sheared the head clean of and i had another 2 or 3 that rounded off so had to drill the heads off and take the spider to an engineer who sorted it for me its a good bit of kit but i will now be using high tensile screws cos the ones supplied were either stainless (always seem to cam out and round off) or just too soft for my hamfistedness i also had a clearance issue without the spacer but sorted that with a gasket each side of the spacer and had to use the xl2 thrust bearing (thanks max) to get the clutch arm in a decent place in use its brilliant even with a short arm cover its not too hard to pull in, no drag or slip whatsoever, you can put it in gear and move backwards unlike the wanky single spring 4 plate i wouldnt say its hard to fit, but a lack of instructions and just a box full of clutch parts is a cunt, i couldnt get the clutch primary in while attached, and nor could i build the clutch out of the motor and fit it, maybe its just me, but got sorted in the end
There's a quite a lengthy topic on the GSF with an instruction, little enough help for you guys though. I'll tell the manufacturer that this is a problem. Not sure he'll do anything about it though, he's a scooterist who runs a CNC machining place, and with economy as it is just now they are superbusy with their everyday work that pays the bills and there's little time to cram in hobbyhorse-projects like the scooter stuff (he's also designed a number of other things), so maybe he's just to busy to bother.
Whatever oil you end up using, make sure it's JASO specified (wet clutch use).
Thankyou for the information Jonny and Mathias, I put the top plate screws in with my battery drill set on the lowest torque setting but when I build it for use I intended to use medium strength thread locker for these and only hand tighten, should be ok. Had the same issues as you Jonny re figuring out it wont fuckin go in all together lol but I approached it with expecting problems to fit as there were no instructions with it and knew I'd have to learn how to do it anyway as it was second hand but I would at least think it would come with them new, thats just stupid, especially at how much they cost, but with SIP supplying it I couldnt find any instructions from them either, it isnt hard to fit just a bit of pissing around to sort it but i actually enjoyed that too ;D www.sip-scootershop.com/en/products/4stroke+oil+castrol+act++evo+_14184901 I got this oil which SIP recommend to use with it Mathias, should be ok?
Screws are 10.9 torx now. Nothing wrong with that.
well i guess its just me then or the locktite, i torqued them at 4nm as i had no idea what they were(no markings at all) so too much for 8.8 but not really enough for 10.9 , i use wera torx bits which are quite good too, tho there might have been a stray one i now have some black oxide 12.9 socket head screws which i will use at 5nm
never used that oil eean or seen it here, the power1 is jaso ma2, tescos sell it for a tenner or so
