I guess you have a different way of looking at things, to me it just feels like it is telling me to "Back off, I ain't going any higher"
My head kind of feels that way now from this thread, if going above 5200 or 6200 is that important to you, maybe you should buy a different bike, I hear rice grinders can go as high as 12k. Harleys are cruisers.

thanks for the replys but now i am getting more confused. there are conflicting statements in the replys. Again my dealership told me my rev limiter was set at 5200 rpm's . the beginning of redline on my new speed/tach combo is 5200. He then said with upgrades it will increase to 6200. you all agree. So why wouldn't I get more power and speed with a longer gear range with these upgrades without cams and so on just yet ?

I have a two stage rev-limiter setup on my supercharged mustang for drag racing. The first revlimiter works only when the cars isn't moving and it is set at 3,000 rpm, second stage is set up at 6,000 that kicks in as soon as the cars start to roll, but my redline(shift point) is always at 5,800. This way I can sit on the line with the gas pedal floored waiting for the tree to turn green.

Yup, I look at it this way too, thats why I differentiate between redline and rev-limiter.

When I was drag racing we only used forged steel cranks and roller camshafts and lifters so we could increase the redline dramatically, but we also built the rest of the motor to produce power up there.
Without the ability to make use of the increased RPM's WTF are you worried about it for?

I guess you just proved my point.... If you are actually building a race motor it certainly matters, for a street cruiser, it is pointless to differentiate because you have no useable power there anyways on a stock Harley.

I agree with you on everything except it being pointless to differentiate. Fact is you can still change the rev-limiter on a stock engine and as proven in this thread not everyone understands that you may not see any gains from it. I'd rather differentiate the two to prevent confusion.
