Hey, JC,
On the '12 Street Glide, the first comp was bad at about 5000 miles. At that point, just a pipe and fuel controller. At that time, Jim at Metal Dragon installed cams and a 30t front sprocket. The next compensator was shot and replaced at about 12,00 miles, when I put in a 113 kit. I traded in the Street Glide at 20k, and the compensator was bad again.
On the new Ultra, by 5000 miles the compensator was clunking worse than I've ever seen, so I decided to try the BDL. So far, I'm at 20,000 miles, and it's working perfectly. That's 15,000 miles, which is a record for me with compensators!
I'd also like to know why I'm so hard on compensators. I drove aggressively with the SG, but I've been babying the Ultra, and it hasn't made any difference. I do an awful lot of riding in the mountains - Big Bear, Idyllwild, the Angeles Crest - and I'm wondering if that's the problem? But I'm just cruising like an old man, not tearing up the roads...
