I usually cruise at 3000. Hit the limiter lots pre Stage 1, but not since. Regular shifts are 4000-4500. I feel that 3000 area is the best cruising rpm for the bike. My test was to find a straight flat stretch, put on the countdown to empty timer, and check remaining kms at about 115 km/h (70mph) in 5th gear around 3000 rpm, then maintain the same speed in 6th around 2600-2700. I've found it gave a higher number of remaining kms in 5th at the higher rpm. Result=more torque on hand and better fuel mileage...a no brainer in my unscientific test!

Since HP is only the result of a formula with inputs of torque and RPM, HP will always be higher as RPMs go up, at least until torque drops way off. Your best RPM range would be whereever your peak torque is found. That being said, you would problably find youself somewhat above that range when passing on the freeway or running from the highway patrol.

So I've been testing this theory for the past couple of days and while it takes some getting used to (not shifting at the start of the whine), I do believe that I'm getting more out of each gear and the bike certainly feels happier/snappier at the top end.

Thanks for the lesson.

If I am trying to move fast, I let the seat of my pants tell me when to upshift. As long as she's pulling, I hold out for the next gear. Sure, you might hit the rev limiter every rare occassion. No big deal. It won't hurt it.....I pretty much thought anyone that operates a manual shift vehicle did the same thing.
Very well said.

I'm at 2000-4000 rpm 99% of the time.

these twin cams like rpm's more then previous engines. they dont like to be lugged. it is important for longevity of motor to keep rpms above 2200. remember t/c 's run extreme lean below 2200 and if run above that gets more fuel for cooling etc

I find that if I keep her at about 2200 rpm in 4th gear around town that equals about 45 mph. Did that for a tank full. Kept shifting at about 2400 and run around like that I got 44 mpg!!

I rode a lot better without a tach on my RKC than I do with my SG. I had no trouble cruising 80mph on that 88 egnine in high RPMs, but I seem focused to much on the Tach of the SG. So I will start riding by the seat of the pants again, except when I follow that Honda with strait pipes.

Lucky for me I broke my SG in at 4500 to 5000 rpms for a few runs.
