Has anyone replaced the stock sprocket with a larger (I think 34 tooth) piece to reduce revs on the highway? I have a Road King and this seems like a more affordable alternative to investing in a 6 speed.

Any thoughts and/or experiences?

Thanks!

 

What RPMs you are cruising at now at your desired highway speed?

 

I am spinning about 3000 at roughly 70 and about 2800 at 65. I'd like it to be at about 2600-2700 at 70.... This is with an injected twin-cam Road King.

 

I did the math on it this year when I had the primary off, and decided it wasn't worth it. I was looking at changing my engine double tooth compensating sprocket, not the drive belt sprocket.

1. You gain higher highway speeds at lower rpm, but you have to gear down more to pass, or when you are heavy.

2. You only gain a 7% reduction in revs with a two tooth change, and I'm never that close to maxing out my comfortable rev's.

3. Your bike has the potential to lug more in quick reduction of speed.

4. A wrench who I really respect told me that by using a 6 speed, I would not lose the rev's in lower gears, and I would get lower rev's at highway speeds.

That's why I didn't do it
