I put on the SE and there was no requirement to balance it. It was a big improvement over stock....If you are taking the time to open it up why put the stocker back in, it has a history of problems...just getting rid of the starter clunk was worth the swap and it runs way smoother..JMHO

I also installed the SE comp and cut oil grooves, have not had any issues, no vibration issues either also runs smoother and less noise going down the road.. Just didn't like the grind bang at start ups was the reason I replaced mine and to me the bang would always eventually cause the bolt to loosen, but cannot confirm that, just makes sense. Also Harley makes upgrade parts for a reason and to me they will make sure you have a reason to install them. Just like the junk press together cams, if you have them in your motor I would highly suggest that change as well, ask me how I know...
BTW this is the first I have heard of balancing the comp, who and how is this done?? This thing has a chain that runs around it so what good would it do to balance???

Guys I never said there was anything wrong we balance them in house and lighten them up a little. We treat them like a harmonic balancer. Every time the cylinder fires torgue goes right to the crank. Cranks deflect under this torque. This will make virbration. We just try to balance and lighten to help with this issue when we build motors making big power. Here is a dyno on a bike we did this with 2010 ultra 131 inch motor we built 224hp and 194 tq everyday rider with a blower. This motor purs........ If you want pricing please call or email I cant not post here pricing others get made.
I can go in to more detail if you like. We are not saying you have to do this it will work fine. But this is are std to balance. We like things to leave here in great shape and no issues.
Thanks FD.

Do not waste your $$ on the BDL. I tried one and it really is not a compensator. As soon as you start the engine the sprocket rotates and locks into position and it is a solid sprocket from then on. You do not want to have a solid sprocket on a 07 or later the crank is far to weak to take that kind of load. IT WILL BEND. The BDL folks will sell you their sprocket but don't offer the spacer required to align it. I had to make on on my lathe. But like I said it locked up as soon as the engine started. The SE Comp. is designed to take the added power and will rotate much farther than the stock or the old style this absorbing or load will help prevent bending the crank. This is necessary due to the fact that the crank is weaker than the older ones. This is because the MOCO has made it hollow so the comp can be attached with a bolt instead of the nut like the old ones. I have spent the last 18 months studying this comp and have over come most of its weaknesses. Way too much to put in the reply. You can read all that has been done at Harley Tech talk - forum -twin cam - SE Compensator by Richard K. it is 13 pages long but packed with information. Hope to have something available later in the summer for anyone interested and does not want to do it yourself. Check it out well worth you time. Yes Dragos is correct it needs to be balanced this thing is a 14 lb mass spinning on the end of your crank
