SF Fork oil

[Fitz]

Hello all, can you confirm suitable fork oil for an early Ceriani SF750 front end (drum brake), I see from my Green book the quantity is 170cc of SAE10, just wanted to check your experience before I fill them, done the seals etc obviously. Incidentally I have found that the dynamo belt somebody pointed me at (Z19.5/ 10 x 500) is far too tight, it would eat the bearings it was so tight, i tried it today and have now ordered one at least 20mm longer, I will report what that fits like when I get it. I use a UK engineering supplier that has useful little on line tool for sizing belts, their system said 524mm, the closest they have is 520mm so I wil try that

My SF1 was indeed 170cc and 10W should be fine. They work well and aren't a fussy fork.

The genny belt sizing is indeed a puzzle. There is a fair bit of talk on it in Marty´s around Australia thread.

Thanks all, Ill let you know how I get on with that belt

is it a dynamo or an alternator, the alternator type has a longer outer cover for obvious reasons as in ex Kuwat GTL.

Seriously doubt he'd have an alternator on an SF750.

Take it your talking about Cerriani 35's. Yes 10 SAE Bel Ray if they are in top condition perhaps 15 weight if not, 20 weight is HELL and time to rebuild your forks.

You should always flush out and refill your forks every 2 years.
