On the other hand, the compensator is as worthless a part as has ever been put on a motorcycle, and is more than a little bit prone to having problems.
I put 300,000 miles on one of my FXR's without the compensator and have put many, many thousands of miles on all of the other Harleys, I've owned without the compensator.
It's a heavy, useless piece of junk, that has no discernible effect on the performance characteristics of the bike....Just replace it with a sprocket and be done with it.
Compensating Sprocket not needed...

That company also makes a 25 tooth... and other company's make 30 and 32 tooth.......... LOOK !!!!!!
Come on guys, really?
Open primary's and even enclosed belt drive systems don't run compensating sprockets.

When you talk to virtually anyone who has owned one, the story is always the same: lovely to look at, ok for very short trips to the local hangout, but no way comfortable and no way reliable.

As for reliability - buy a good product and it will last. Buy a cheaper made product made from softer material that depends on lots of red Locktite and you'll get what you paid for. I went with an R-P belt primary, and yes, the Rocker and BO are the same offset. The only thing I'd do different would be to go with a 2" wide belt instead of the 3" for more clearance.

Even manual transmission cars have a form of this, incorporated into the clutch plate.
It might be a little like torsional vibration dampers on automotive crankshafts. These greatly extend parts life by reducing twisting of the crankshaft, and transferring power more smoothly (less jerking) to camshaft drive components .

The smoothness, and the durability, of custom bikes with open primarys and enclosed belt drives are not exactly wonderful . . .

Just thinking.. any HD in a really tight RH turn,, you may have to slip the clutch...
If you're getting 51mph out of 1st gear.. then accordingly to the RPM VS MPH Calculator I have, your winding you ""B"" motor around -- 6500 -- rpm's..
If so, then I am thinking unless you've had you crank welded and beefed up I question your or the tuner's decision to allow the engine wind that high of rpm's.
I think the 14's have the Se comp in them.. If right. your can't get much better..
I think the comp helps mostly on startups and then during high TQ applications while running under loads...
In the yrs past in here, their have been Many threads on changing the gearing..
Do a Google Search on your questions if you don't get the answers you want in here.. and I am sure you'll find more info than you can read about how and why...
