pierodn,
This information is found in the
Maintenance and Instruction Manual for G85CS, G80CS, P11. Scrambles Motor Cycles
Page 6... give you capacities.
Page 13... for Chain Lubrication information.
"Use engine oil to lubricate the front chain which runs in an oil bath. To top up, place the machine on both road wheels and pour in sufficient oil to allow the lower run of the front chain just to make contact with it. " I left out the rear chain.
Hope that helps.
The Commando has a more flat run to the chain case bottom section than the P11 with a single chain. The P11 more egg shaped. That is my guess
And a Happy New year to you as well.
Cheers,
Thomas
