Burning clutch plates out...Now with Photos

[goldeneye]

phew! how old are the casings? some older px casings have a web of ally in where the clutch sits, also the clutch cover has a web of ally that needs grinding off, both can interfear with the fitting of larger 200 style, and cosa clutches. also, the thickness of the large washer, or oil drive cog behind the clutch can interfear with the actuation of the clutch. i wish i had it in front of me for a proper look. SIP do a thinner washer, but ive successfully ground one down (they are hardened steel) and used it. (without autolube. i disconnect it on tuned motors whenever possible.) the smallblock motor i have now has a cosa clutch, and the webs of ally ground away, and a thinner washer, all to make it work. been no bother for 1000"s of miles. keep us posted. Dazza , you still need that battery tray?

well heres my two penneth
The tongue damage looks typical when using a flywheel that is too light such as the HP4 type
The burning out prob of the plates could be caused by the omission of the white plastic/nylon oil thrower ...
.and the above two probs could be compounded when using a bigger diameter clutch in 125/150 casings without removing the alloy ribs in the main case or clutch cover .

SIP re enforced Clutch basket arrived (thanks to Tom at WSP for fast delivery & at great price )

Fitted at Classic in Notts with Newfren Carbon plates , XXL SIP springs and with new primary drive.

Didnt eat the clutch (which it had done with the previous 4) but makes a really odd rattle on changing down ????????????????

Things mentioned so far,
1) Clutch bedding in?
2) Gears catching each other ?
3)Result of mixture of newfren Sip and Piagio parts?

Going to give it a propor run on the QMC hospital charity ride out in Notts Sunday So Fingers crossed. However will have trusty AA card in pocket.
