Engine oil

[DAVE01]

I would definitely want to try AMSOIL, though it's not easy to get. Therefore I use whatever is recommended by Roger Heyes, in this case, Motul 5100.

I just got my last lot off ebay
We have used it for years,dad and I have run it in methanol speedway engines with out any trouble [motors usually only pulled down after a full season]I run there oil in my chev stroker ,SS holden etc and luv it.
My hayabusa clutch was slipping and biting occasionally when taking of in first or sometimes when releasing the clutch when doing a slow u turn etc,Amsoil now in there for 200km and clutch is fine and engine seems much quieter.I put mobile 4t semi syn in the bike the day I rode it home and then changed to Amsoil 2000km's after.
