This. I do my primary every other oil change. Brad Penn 20-50 in the motor,Mobil 1 75-90 in the trans,Valvoline 20-50 MC oil in the primary.

Motor about every 5k give or take. The primary, about the same.I'll do the trans every 10 k. Being I use gear oil I might let the trans go a bit longer. Heck some people never change the trans oil in their cars and they go forever.,,
 
Isn't 5000 the interval the Motor Company recommends? When using the specified grade of oil?

I have a Revolution engine, so it's a shared sump.

It gets changed at close to 8,000 Kms as possible.
But has been pushed out to 10,000 Kms on one occasion.
 
Ducman don't tell anyone over on the duc forum but I'm a secret admirer of the Harley Dyna FLD switchback! Might be my 2nd bike someday. Everyone needs at least two bikes, right?
