Hello Simon,

makes sure that you use one without the wear-oil additives. Otherwise the clutch slips. Using normal hardware store oil in this respect is not good enough. Use Miller Oil M30.

SAE80 my opinion, is too thick. In colder temperatures, it should cause problems when switching.

Another tip: do not fill the motor housing to the "full" mark, but only as far as the teeth of the gears are in oil. This is completely sufficient for the lubrication of gears and shafts and the clutch will thank you. Disadvantages: Frequent check the oil level.

Hi Martin

I had to order some Miller Oil M30 online as non of the bike shops near me stocked it, although i did have fun explaining what and how old my NZ was!

Incidently, I have just finished putting in the new wiring loom and fitted a Powerdynamo conversion. Hopefully my NZ 350 will come to life this week!!

Regards,
Simon

What advantage is there to filling the motor housing to less than the full (Voll) mark?
