compensator,compensator that seems to be a buzz word.
I put over 75,000 miles on an 07 not one issue current owner has over 80K on it now, about 40K on 2011 103 rgu Not one issue until I totaled it. Almost 50K on the 2013 103 until traded, current owner very happy with it.
These engines need ACR on them. There is good reason HD made the standard on the 103's.
When you have engine work done it changes the game ,When that TC86 was built to the 103 if the CR were not right it is hard on every thing from the battery on down. The higher draw by starter wears battery down weak battery adds to the problems. Often with 103 kits you see the ACR not done to save cost. A short cut that comes back to haunt you latter.
I know and ride with a lot of Harley owners riders that do put on some miles , Not 1 of them has ever had a compensator fail not 1.
Can it happen sure .

Just because you haven't experienced the problem doesn't mean it's not a real common problem. I read about the 110" lifter issue all over the place and I personally never had an issue with them in over 50k mi. Also have 3 close friends with CVO's, that ride a ton of miles, and only 1 of them had the problem (it was at 40k mi.) so I know it could happen but in my real life experience it didn't seem as common as what I was reading.

The comp issue is real common (I've had my dealer tell me as much) but keep in mind that that when you read issues like this on a forum you will always get way more people talking about the problem (especially if it has to do with MOCO) and not very much on the successes so it seems as though every bike will have that issue and in reality it's not as high of a percentage when you consider how many bikes are out there.

Could compression be causing his issue? Sure, but on his setup it is way more likely to be a compensator issue than it would be a compression issue.
