I came to riding at age 56. I've always been the DIY kind of guy. When I look at my V twin, dry sump, air cooled, soft tail I don't know where to start. Things like oil changes, plug changes, filters and such are things I've done all my life. When I look at that engine it might as well be made by pratt-whitney. My 1000 mile check-up (underline check) was near $500. I was shocked, I was new to HD Dealer service. No comps on service there Today, with the help of the forum I fixed a low speed wobble and clunk on braking and bumps. The socket cost $8.50 and I had a torque wrench. Compared with the labor rate, DIY as always, is better. So, the question is, how much should I learn about the mechanics and maintaining of Mr. Harley?
