Dealer sold me Suzuki gear shaft oil (made for Suzuki ATV diffs) and said to use that in the Cforce 600. I see in the manual it says 80w90 GL5. So any good 75w90 should work.

Manual says change every 50 hours, but I think its a good idea to change it at the end of break in at 20h/200 miles.

if anyone has a digital copy, I am willing to send payment if it can be shared. Thanks

Normally this is not usual, but on these 2020+ Cforce 600 it seems to be normal. My sample size is 4 of them now and all do this, all new machines also, 2 of them arent broken in yet, they make a backfire sound a pop when letting off the throttle when under load. I asked the service tech at the dealer who said it is normal on these. It is not overly loud or excessive.

For anyone wondering, stock clutch spring on the cforce 600 2021 is the 1013 (200/400) its marked gold yellow blue.

The weights are 10g and the weight holder is 10g on a food scale.

The secondary is clocked to B1.
