A little rant: While I love my Roadmaster, IM should seriously consider firing the engineering crew that developed the drive belt adjustment system. This is the worst system I've encountered. Adjusting my HD belt was so much easier. On the HD, there are two cam lobes on the rear axle...one lobe touches the left swingarm, one touches the right. When you turn the adjustment lobe, it moves both the R and L side lobe at the same time...no guess work. The IM system reminds me of something you'd find on a dirt bike. Just adjusted my RM per the service manual and belt tracked in the middle of the rear pulley. Went for a ride and now it's tracking fully to the right. What a PITA.
