I know how you feel. Sometimes cars give no respect to motorcycles.

No I ride mine for 40-60 miles on average at 60-65 indicated. I have a 42 tooth sprocket on the rear and since you have the SF model and if it's stock I think you have a 39 tooth sprocket. Someone correct me if I'm wrong about the 39 tooth.

It's now Unobtanium. B and B Moto used to make them, but, not any longer. I don't know how many were made...I'm just glad I have one of them!

I just installed mine (Krieger manual adjuster) and what a simple piece of art.
benefits? no guess work in what the factory adjuster is doing and IF it is working.
Drawback? well you have to loosen the locknut and adjust maybe,,,, sometime.
I don't know how often it will require maintenence because i just put it on, but let me tell you how i adjusted the chain.
Start the motor and let it warm up,,, back the tensioner off at idle until you hear chain slack, and then tighten one quarter turn after the noise goes away.
So simple a caveman can do it. I for one was really impressed with it.
I bought it because sometimes when i ride i hear "stuff" like rattling drive chain, harmonics with the intake, plastics vibrating,,,, just stuff.
I want to make sure the "Stuff" isn't my camchain.

Yes you are on the right track.. I was having a hard time maintaining 70 indicated unless I crouched down and was completely on a flat surface.. with a 351 you can sit up and go 87 indicated. I put a speedodrd (speedhealer) so my speedo is exactly same as GPS, and last night I passed a car going up hill at 84 MPH (GPS) going slightly up hill (okay I crouched down slightly) Its an incredible upgrade.
