I'll bet WE ALL get the best MPG at 3k!

 

No, didn't make it. We're trying to finish the wiring in the barn and get water out there before winter. Have to work Monday or I would bundle up and bomb up your way.

 

It's all relative.
Any rpm "hurts" your bike. If the crank is turning and the pistons are going up and down, then the engine is wearing out. The more rpm, the more wear. The newer (and less worn) the engine, the more rpm it can take.
The only immediate danger to the engine is if you are over the redline. Which is, what, 6000rpm on Twin Cams?

 

I seem to get my 'best MPG' when the bike is turned off and sitting in a garage.

 

here is the million dollar question. How long can you keep the throttle wide open before the rev limiter kicks in?

 

About 3/4 of a second.

Do you owe me a million dollars?

 

What he said is correct for engine not under load. If you meant under load, why don't you go ride your bike in top gear and get the data? It would be helpful to know somebody was trying to learn something by doing.

 

learn by doing it myself? you must be crazy...

 

I rarely use 6th gear when I'm doing 65 to 75. Usually kick it into 6th when I'm over 80. Sometimes when I'm on a wide open highway I'll use 6th gear at 70 -75 when I'm just cruising along and in no hurry. If I have to pass for some reason I just downshift to 5th and go.

 

I keep trying to crank on the throttle all the way, but I'm too chicken thinking the motor will blow up. I still have not had the ***** to open up the throttle fully and just keep it pinned there... tonight I did twist the throttle past my comfort point and was awarded with a feeling of extra boost. I have no idea what RPM I was at...
