Just clear up a couple comments here... I run a S&S585 cam and run about 1000rpm idle.... I have 56k on this comp and clutch.. and I run the crap out of it both on the highway and short trips, it never fails to find the rev limiter on every ride! I also pull a small trailer on trips, see pic below. I cruise at about 80mph or so WITH the trailer.. Additionally, I have run a comp eliminator on my Fatboy.. S&S585 and some... hated it because I had to run about 3000rpm to have smooth ride and everytime I hit a bump I could hear the tire chirp as it bounced... took it out and put a Baker in....
Yes,those are sportster wheels.... yes, it has hydraulic surge brakes.... yes, it is a 4-link suspension.... I'm retired and like to build stuff! LOL!
Ive shimmed a couple compensator spring packs with excellent results. Harley actually sells the shims. Takes a noisy, clanging SE compensator to whisper quiet (as long as there is no damage already).
I had good lunch replacing my 12 with the Baker compensator. It went 30,000 miles with no issues when I sold the TriGlide. Why replace the springs every 10K?
My ‘17 Limited went 45,000 miles before I sold it with no issues on the original comp.
BTW, not that it seems to matter. But, I’ve never understood why the ramps are not machined smooth.
I just had to rebuild the primary on my '07 FLHTCU.
New clutch ( aftermarket Kevlar, basket & cage)
New chain (HD)
Tensioner (HD) - I had the Hayden sitting there ready to go in, but the other 96" touring bike next to it just had the Hayden installed and the thing was LOUD, so no thanks.
Compensator (Darkhorse Man-O-War) - This unit can be rebuilt if/when needed.
I've got about 50K on a second gen. It has one extra small spring, one spacer and the later Peek Thrust washer. The second spacer is needed to take up the slack caused by the difference in the Peek washer to the needle thrust bearing. It rattle a under light loads but is working fine. Motor is a 10.5 to 1 107..
I suspect that they are rough because they are hard to machine and they expect them to wear in..
Add:
I've got over 50K on a 17RK with no issues with the comp. Later ones are great..
