I thought it might interest you folks that I dropped my HD Motortrike off with my mechanic today to let him dissect its 6-speed transmission. I have accumulated all the parts to install a Baker F6R reverse gear, and install a 30 tooth final drive pulley (and the proper 132 tooth drive belt). He is confident that he can get it all completed next week while we're at Maggie Valley. We're taking our Nova VW trike for this trip and expect have lots of fun.
