Re gearing. Less r p m.

I have a 82 interstate. Is there any way anyone has found to get r p m down. By mabey. Rehearing. Or new rear wheel, my concern is I'm running 4000. R p m. At 70 m p h. The bike was built when speed was 55. I'd like to find a way to bring it down ?

I didnt find anything useful for mine..Nothing that made money sense.
The 4k rpm is OK.Red line is what..near 8k...your only running just a little over half...my bikes liked running 3 to 5k anyways.No harm ever done.

I'm wanting to get rpm down to improve. Mpg. Even thinking of going to smaller main jets

I am not aware of any reasonable option to lower the gearing on a goldwing!! Shaft drive just makes it too expensive to change.. Be carefull going to smaller jets, you might get better MPG, but if you burn out your valves, or seize the engine from too lean a mixture, the repair costs will completely blow any savings you got from the better MPG!!

The bike is what it is....
Better gas mileage is accomplished by driving a Vespa motor scooter.

Lowering your RPM will not result in improved fuel mileage at highway speeds (> 50), due to the barn door you are pushing down the highway!
Those fours were built/loved to rev.
Use smaller/slower right wrist movements and keep it below 60 mph to improve fuel mileage

My 76 is turning 7000 at 68 mph. I for one love the high rpms capable from this bike. Wouldn't change it if I could. Fuel mileage just isn't very important to me on this bike.

"My 76 is turning 7000 at 68 mph"

Have you considered upshifting?

Wow! I'm so confused. 4000 rpm not 7000 or maybe my clutch is slipping.

My cb350f turns 7,000 rpm at 70 in 5th gear. The redline is 10,000.

Are you sure the tach is accurate?

If that question is for me 7000 was a typo. 4000 rpm at 68mph it should have read.
