I was on a long ride the last three days. And a lot of the interstate was very long, straight and hilly no turns. Speed limit was 65 mph. I had my bike in 5th going 65mpn. The rpms were at 2800-3000 with the cruse control on. Going straight and down hill was no problem but when the bike would go up hill I could hear the engine struggling to stay at 2800-3000 rpms it would do it and the rpms would not drop below 2800, but I am wondering if this is bad for my engine. I also had my wife on the bike and luggage.

 

I would not consider that as lugging, but it sounds as though, you may to consider a bump in power, as that is encroaching the area where you should be well into the torque curve, and by rights, the bike should feel quite nimble there. Something to think about.

I think I would downshift.
It's not gunna hurt the motor to rev.

 

If its not pinging or surging the engine isn't getting hurt. At 3k Harley's are in their working range. This is were they are most efficient. If it bangs, rattles, pings or shakes harder than normal at more than 1/2 throttle then down shift.

 

I have been thinking about cams 204 or 211 the only thing holding me back, is by adding the cams will that take life out of my engine. Most of the time I run my bike at 3000 rpms some times all day (about 300 miles) is this bad for the engines

 

skip the211's and mild cams won't take any life out of your motor. you could run 4000all day and it won't hurt a thing.

 

I change the exhaust but never got the bike tune for the change. Could that make a difference? Beside a stage one down load the bike is stock.

 

Remove your spark plugs....Post pics of those same spark plugs in this forum for a further analysis....

 

That could make a difference. Some say the computer will self adjust with information from the o2 sensors but that is not always possible because some exhaust systems change things up so much that the computer can't help you without getting it tuned.
Also, your bike isn't struggling. That's the way they sound when an engine load is created. It does not hurt the motor to rev either. That's why we have rev limiters on our bikes.
On the other hand, I'm with hillside too. If you have ever felt what it's like to have instant hard accellaration while going 65 miles an hour and still get as good of mileage as you are getting now. You will never go back to a stage I motor. It tastes great! As Tony the tiger used to say.
