I was wondering if we could get a diagram of the BP2. I have been servicing my mk10's and mk2's at home and have ran out of reliable part sources. I have been very happy with my hog 2nd stage classic and was thinking about taking the leap. I was wondering what the price for a d1 vs BP2 annual kit will be. Also which is relatively easier to service. (not to stir up trouble but I'm never going to qualify to be able to take the repair course)
