Coming off of bikes that rev to 9 and 11 grand ,The first and only time i hit the limiter on my TG i thought i was floating the valves like the old V8's of yesteryear. Not a good feeling.:newsmile055:

What some guys don't seem to realize is that if you are looking to spin one of these motors up over 6K, it's best you get a bike that can do it without harming the engine like an import.
The newer bikes (96's) is a suicide run to spin them much over about 5K on a regular basis. You'll find it won't live very long if you do. These engines aren't much more than a tractor motor and you don't see any tractors turning 6K unless the farmer is in a hurry to plow the field .:laugh

Or trying to pull a 65,000 pound sled....:laugh

What about the older 88 inch engine? What is a good limit for long life?

Same for all Big Twins 5500, pre set unless upgraded to 6200, but that is pushing it for an air cooled twin

both my bikes have a tach. i do not take either of them over about 5200, and that is not very often. the 98 has a stage one with a gen 3.5 and the evo has a cam.

Given my experiance with a Dyna, their happy range is 3000 rpm wide. They are happy between 1000 and 4000 rpm. Engines are like wives, keep them happy if you want to have a good life. In the wind.
