atc 110 best oil

[hdeuce]

What is the best oil I can use for my 110? It is a 1985 that is very mint. The shifting on these has always been a liitle sloppy because of the design. I want to run a top quality oil (synthetic is fine) in the cases to ensure longevity and better shifting.

Can anyone recommend anything:

best oil weight
best oil type

Thanks,

Don't use synthetic. Most times it's too slippery for the old clutch fibers. Just use what the factory recommends and keep it changed regularly and clean your oil screen.

Thanks for the tip. I was ready to buy sunthetic.

+1 on that any good motorcycle oil is fine

SAE 30 is what I use in all my 70's and 90's

Is there an oil screen on my '80 110?
