I am wondering how much more weight this would add to the driveline, and if it would be enough to eat up a few hp.

 

I think I'm the only guy here who isn't terribly impressed with the SE Compensator. I made the switch hoping to eliminate hot start kickbacks. It hasn't. Nor can I tell any other real difference in rideability. Waste of money in my case.

 

I installed the SE comp last August while doing a repair on the tranny in warranty. The primary was completely apart and the opportunity was there, so I checked with the parts guy and he actually had one in stock. This was back when they were backordered everywhere and I saw it as a sign from God that it was there for me and that I should buy it. After all, there was no labor charge involved, so that was a big incentive. My tech was very high on them and recommended the upgrade, so I went for it.

I had no real issues with the stock comp except the rifle-shot starting, which never really bothered me, especially after I got used to it. I can say that shifting is now quieter, less clunky, and smoother--but it was really quite civil in stock form, so I can't say there was a great improvement. I would do it again if I did the work myself, but wouldn't pay the $250+labor to have it installed by someone else.

I never had any real problem with starter kickbacks, as they happen very rarely on this bike. Starting immediately after turning on the ignition has largely eliminated this problem for me.

 

i got the se compensator when building the 103 motor and the compensator i already knew was a huge improvement over the stock one. with the stock one there would be times when it sounded like someone slapped the primary cover with a piece of 1 x 4 lumber. that's very hard on starters. the se compensator works like the stock one but has a much heavier spring that will not wind up like the stock one. it just improved everything about the way my motor runs. the starting alone is enough to make it a worthwhile improvement along with the improved engagement from motor to trans without that rubbery feeling you get with the weak stock compensator.

 

I wanted to do the swap without loosening the inner primary housing , so I had to grind some material off it with a burring bit , and it went quite easily.
My dealer quoted me $250.00 labor , so I figured it couldn't be all that hard for me to do.
I did not have to touch (remove) the clutch basket at all , as I didn't take the original comp off in 1 piece.
You assemble the new comp on the crank and have enough room to wiggle the last piece and the chain back on the clutch anyway.
I made a locking tool from a 1 1/2" x 1/4" steel flat stock 5 7/8" long with radiused ends to remove the original comp.
You will need a 1 3/4" open end wrench to hold the new compensator and a 13/16" socket and torque wrench
to tighten the new comp bolt.
You will need a new primary gasket and 45 oz of primary fluid (for mine).
You also need a fairly strong zip tie for the tensioner
It took me about 2 hours to complete , but I could do it in an hour if I did another one.
I had to remove enough material from the inner primary to get the rotor off the crank , I did this very slowly and methodically so I didn't have to affect the sealing surface of the primary housing itself.
The shavings are non metallic so they clean up easily.
I made a shavings shield out of a large piece of cardboard with the new primary gasket as my guide , cut it out and poked a hole for the crank.
I wrapped a rag around the rotor and then put the cardboard shield over the crank while I ground the case.
I didn't want to pay retail , so I waited for a HOG day at my dealer and got 15% off the comp , gasket , and primary oil.
The results , I'm very pleased to say , were worth it to me.
No more starter "bang" nearly all primary noises are gone , and I can pull 6th gear from 50 MPH without a hickup.(not that I normally do this).
The bike runs a bit smoother overall , but much smoother when my wife is on the back.
A funny note , the parts guy says " what's this going to do for you?"
He'd never ordered one before , didn't know what it did , and thought I was a little nuts.
I had my stock comp loosen last summer and it was never quiet after that , so I'd been thinking about it since.
I installed the new comp at 7500 miles and with 10K showing now , I'm pretty pleased with the results.
A very worthwhile mod in my opinion.

Could you tell me whats involved with the Isolated Drive System. Sounds like something I need to do. thanks.

 

could very well have been,noticed it was louder from when bike was new id say.orig.comp wasnt like falling off,it was still snug.but could have used pliers to remove. orig comp wasnt really worn either.

 

when my 96" was stock the tranny went from nuetral to first with a loud clank. after the 106" build, I think that the new compensator made a difference, now all I hear is a slight "click" when engaging first gear.

 

OK, hope this isn't a hijack. Have been contemplating the SE Comp on my 08 due to mods although not having any real issues. Maybe when I throw in the cams this winter I will do it at same time just to be safe.

My wife's 07 RKC has no mods except for nice sounding V&H ovals. I have noticed however her bike is "rougher" on acceleration then my 08. Kind of a deep vibration? Hard to explain but reading this thread I am wondering if putting the IDS on her 07 might smooth it out a bit?

 

When I had my '07 RK, I upgraded to the IDS and it was a VERY beneficial change. It changed precisely what you're talking about and made everything much smoother.
