I've bought a new 08 dyan WG back in 08 and love the bike. I added SE torque slip ons, a high flow breather, and did the TTS mastertune work. It runs great and when I sit back and ask myself, what would I do to make this bike even better? I come up with two things.

1) the SE compensator
2) automatic compression release

These are the two things I think would benefit the bike. Especially the automatic compression release. The starter motor on my bike is up to the task but just barely and when it does fire off, you can hear it max out the compensator. Has anyone done this mod to their dyna? I know the Motor company builds a jig for the boring but I'm a little nervous to tear my bike down and do it. Any companies out there that do this work?

Thanks
Richard

 

interesting, I wouldn't think you would need either one one those things with stock motor

 

Yeah you'd think but after having owned the bike 2.5 years, my experience is they are both barely up to the task.

The auto compression release on my 110" screaming eagle works like a charm. Fast spin and no bang on start (my SE also has the SE compensator).

 

ACR is a waste unless you plan on doing a big bore with a good bump to your stock 9.2-9.5:1 compression ratio.

Maybe you don't understand what they do. I'd research both mods first.

 

Is your motor 96"? Shouldn't need compression releases. I have the S&S manual releases but I'm running a 117".

 

I have both the se compensator and the acr's. The acr's are more involved than you think. Not only do the heads need to be machined for these to fit, they need to be wired in and then programed to work. As for the se compensator, the stock one should work fine with a stock or mildly modified motor. Unless you start putting out some serious torque, leave the stock one in there.

 

If you are running stock cams and your starter is barely turning the motor over as you describe you are better off spending money on a new battery. If you have upgraded the cams and are making more compression then maybe you can benefit from a compression release. If you are thinking of upgrading the cams you may want to consider the S&S cams that have the compression release built into them.

 

DCLXVI S&S has a cam that has a compression release in it? How do they do that? I'm not that mechanically inclined, but I thought the compression release valves were machined into the heads right next to the spark plug along a parallel axis not incorporated into a cam.

It is the Easy Start Cams from S&S... I beleieve that is what DCLXVI is talking about.

 

I have auto compression releases on my S&S 107 motor. They came as part of the package and work just fine, with my original and stock 1990 starter! If my 20 year old starter can start a 100+ HP motor, it should be a breeze for yours to work properly!

If there is a problem starting your bike, check the entire electrical system connected with the starter, especially all connections and grounds. You should be able to fix it for nothing more than a little spare time, then move on to something more interesting and worthwhile!
