Sounds good in theory, but I can't up shift, there is no 7th gear.

These engines arent designed to do high rpms... The power curve falls way off so what's the gain?

Thats what Rice is for :-)

Exactly. Unnecessary and more likely to blow something than accomplish anything else.

I haven't hit mine much, but I have been known to bottom out quite frequently

I run my scoot hard all the time and not once do I recall hitting the limiter, I can feel when there's no more power in the gear I'm in and shift accordingly.

It seems none of them ever tag their rev limiter … even with the stock setting.

Is it just me or does that sound odd to you?

Hell, I bang the limiter in my car almost every time I drive it.

FYI – With the higher PCIII setting I no longer reach the limit.

I agree that on a HD this is not something you should do consistently, but now and then just ain’t gonna hurt it. It tends to occur when my regular buddies and I are leaving a stop light. One of us goes full throttle and the chase is on. With all that noise it just sometimes happens. I only ask the question because of the surprised reaction I received the other day. They were not the guys I usually ride with, and just stared at me like I was speaking French.

I hit mine occasionally, usually when riding with loud bikes. The main reason engines that hit the rev limiter often come apart is the owner adding more go fast stuff. If hitting 6000 rpm shortens the life of a engine, it wasn't going to run long anyway.

The OEM rev limiter is set at about 5400, gurantee that considers a wide margin of operational safety, since you can raise it to 6200 without any problems via PC or HD download. While the power does start to drop off in the high RPMS, the bike doesn't stop pulling the moment the TQ curve breaks over the apex, the machine is already in motion so it doesn't require as much power to continue accelerating. They are designed to do at least what the rev limiter allows, hence the rev limiter. If they were only good to 3500 RPMs, thats where the rev limiter would be set. That shifting at peak TQ technique is a much more abrupt power transition between gears, power drops back further in the curve in the next higher gear than it does shifting after the curve starts to dip, which puts you at a stonger point in the curve in the next higher gear. Theres also nothing wrong with riding easy, but my bike, I pay the bills, I do the wrenchin, I ride it the way I want. You can make up all the excuses in the world to ride it like a moped if you want to but there is really no need to look for reasons why somebody else is wrong for the way they ride. It ain't like I'm riding your bike hard.

I was thinking the same thing

I have never hit it and I ride hard at times. Is it posible my 05 RK doesn't have one?
