does anyone have any advice on cleaning std 4rt clutch plates,also after returning rear shocker to factory setting.cheers.

Wash them in petrol, or buy some brake cleaner spray and use that, or buy the Mitani plates, they're really good and if you take them out and flog em on the bay when you sell the bike you'll recoup some of the cost of having a clutch that works properly.

Rear shocker, standard settings:

Spring free length: 133mm

Spring length under pre-load: 126.5mm

Adjuster setting: 10 clicks from "full hard"
