Hi,
For C15 fork oil the manual states SAE20 - is that the same as 20W?
Thanks,
Phil
Yes I am sure that is ok for the forks.
Advice is not to put too much in the forks, I carried out a service on my C15 forks last year and the forks leaked over the garage floor for ages, they have now stopped leaking and operate perfectly satisfactorily.
Yes 100cc per leg. When I got my C15 the forks were leaking but they had far too much oil in them, draining and putting in the correct amount in solved the problem.
