Learned a quick lesson about Baker RSD transmissions I thought the forum might find helpful. My '07 K9 just reached 10k miles when the trans seal on the right side started leaking suddenly and badly. I thought it was just a bad seal. Took it to my local service shop who still sells Big Dog bikes (some carry over new, and many used). I had just changed trans fluid a couple weeks before but they found metal shavings in the fluid. When they took the trans apart, it was full of shavings. The main shaft had wobbled enough to take out the seals and bearings. Required complete $2700 trans rebuild. Shifts noticeably better now. Big difference. The shop told me this is a very common problem on RSD Baker trans. especially on Big Dog's. My buddy is now worried about his Am. Ironhorse RSD which is leaking like mine did. Baker now has updated partes to deal with the problem.
