Hi,

How much and what type is best. 1980/81 349??

thanks

_{I use 300mls of EP80 gear oil in mine without problems.}

You can use ATF in the clutch , but for best results use a straight 30 grade oil like Morris golden film.Fill to the level screw in the casing.

And as above for the gearbox,80 or 90 is fine

Many thanks for your help..

Any idea on fork oil quantity? 180ccs??

Yes anywhere between that and 200cc's, 10weight can be a bit slow especially when its cold,if so go to 7.5 weight
