My last oil change was 4k miles ago so I figured I was overdue for another. It turns out the 1990 Honda CB-1 service manual recommends oil changes at 8k mile intervals. Does that sound excessive for a high strung 13.5k rpm redline engine with a wet clutch? No trackdays just weekend twisty stuff.
EDIT: Bear in mind the manual was written based upon oils available in 1989. Not sure lube technology has changed in 30 years as significantly as marketeers would have us think but I'm not an expert.
