Does anyone here know on an 07 or 08 how far the IDS moves the pulley over from the stock pulley position? It looks much closer to the swingarm then where the stock pulley is.

 

On an 07 RK the answer is not at all.

 

At the time I installed my IDS, I had a lowering kit on the back and can remember that I was concerned that a part of the pulley was way closer to the lowering kit and swingarm than with the stock pulley. But this was on a FLHTCU. I would think all touring bikes would be the same.

 

I noticed the same on my 07 RKC. After IDS, the pulley is alarmingly close to the swingarm. Can't be more than 1/16" or so. That said, I didn't notice before IDS so can't say for sure. And, 15K later, it's never been an issue.

 

Funny that you bring this up - it might support my hypothesis on another thread.
My thoughts are that the offset you mention might be determined by the rear pulleys bearing placement. If the bearing is pressed too deep or too shallow in the pulleys bore, it will move the pulley in or out accordingly. I don't know what optimum is, but too much either way could possibly impose too much side load on the bearing. In turn severely shortening the bearings life span.
I wish I could give you the proper specs - but I don't know them. I believe HD has a special tool for pressing in these bearings - likely with a depth limiter?

 

Center of stock pulley is recessed and IDS center is not to allow room for the rubber inserts.

That may be true, I had mine pressed in by the dealer and, knock on wood, have over 12000 on it without a problem, I bought a replacement and was going to change it out with the tire but didn't. Is it possible to locate the bearing too deep or shallow and place sideloading on it?

Hey maybe someone could measure the stock sprocket outside flange to the inside side of the swingarm, and others could measure the outside flange of the IDS to inside of the swingarm.

 

I installed my own IDS....Pressed the bearing in, there is no choice, bottom it out in the bearing housing. 3 new spacers and no problems.
You can't "space the bearing"

 

Did you also notice the IDS pulley much closer to the swingarm when you installed it? I'm guessing it moved over about a 1/4" But I could really use the exact number. I need to make or order a sprocket spacer with that thickness.

 

Here is the part numbers Both on the L/H side
Inner spacer 11846
outer spacer 11844

Yes it did move it closer. The outer spacer is the small one and I have about 1/4" or less clearance.
You could call the dealer and ask them to measure the spacers for you...
