I've been riding this about 5000 miles. Trying to keep my RPM above 4000 rpm on shifts. Ride at 4000 and above. I do this because of something I read here last year. The bike runs just great, no complaints.

So is this idea about the twin engine being happy at higher rpm written down anyplace? I did't see it in my owners manual. Is there a factory spec in writing?

Just asking. No problems.
Thanks,
daz
