I rev mine to 7000 regularly. It's still pulling at that rpm, peak horsepower is just over 7000 so it's pulling much past 5000 rpm. As has been mentioned you ain't gonna hurt it. It's not a cruiser engine although you can creep around at under 3000.

There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.
Should I roll off the Throttle when upshifting, or maintain the position? What are the best RPM's?

I'll rev mine to that occasionally, but peak torque is at 5,000, so for normal every day riding around town and such, I don't go much over 5,000 RPM. It's a decent torque motor, but you have to be careful not to lug it down at 3,000 rpm or less. I don't rev it out to 7,000 in town as it feels a bit frantic and I don't need to be pulling full power.
To be fair, lower RPM while cruising along at a constant speed is not the thing that's most harmful, it's pulling under load at lower RPMs, like going up hill or accelerating and drastically short shifting. I'll engine brake at 3,000 RPM in places, coming down the canyons, and that won't be unduly stressing the engine.
I tend to reserve revving it out a bit more for freeway on ramps or coming up to speed for a merge. I'm not afraid to rev it, I just don't need full power most of the time.
It cruises at freeway speeds between 3,500 and 4,000 RPM in top. If it drops below 3,000 because of traffic, I'll downshift a gear into fifth.
Up in the mountains, I tend to run it up to 6,000 or even 7,000 RPM when necessary, because at my altitude of 5,000 feet, peak power is down to about 100 BHP, and at 10,000 feet I'm down to only 87 BHP! Peak torque at 5,000 RPM drops from 96 lb-ft to 83 lb-ft, to 72 lb-ft. The loss in power and torque is quite noticeable. It runs smoothly at altitude, just feels a bit, well, quite a bit, sluggish.
Altitude makes a big difference as to what I run it up to, especially as I'm always two up.
