Yes it is. I checked using a tool to measure from the center of the axle bolt the front of the swing arm on both sides and Ive got it right on the money but the belt is tracking to the outside edge of the rear pulley. I was told that this is normal. I did have it to where it was riding straight down the center of the pulley but the tire wasnt tracking perectly straight with the measurements on the swing arm. so i put it back to the specs and the belt tracks the outside. It never made this noise till i changed the front mount. Its funny that Gary7 now has the same issue and i never really thaught much about it till he posted on this.

damn, posts like this concern me. I have my TT sitting in the box, still waiting for decent weather to get some good riding in, so I can get a bench mark for the TT effects. I've been thinking about this install quite a bit. I'm thinking about only removing the lower bolt, putting the TT on an angle to the frame mount, putting the new bolt in, and then rotating the TT to put in the 2nd bolt. That way I can avoid the engine shifting/moving.
For the guys who have already completed the install, think this would help?

When the old lady rides with me I ride around in third gear around town, getting some good vibes going, then I hear some moaning in the back too. When I upshift to fourth the moaning goes away as well as the vibes. When the engine dropped the rear mount at the swingarm might have gotten out of alignment or loosened up. I'd check that mount.

I dont have the TT on mine,just replaced the front mount. The swing arm is attached the tranny case, so it cant twist or change just from the front mount beeing replaced. the rear wheel and drive belt and swing arm are part of the engine,tranny and not connected to the frame in any SOLID way other than rubber. I dont have a sevice manual, so could you give the this procedure?

need to do the engine alignment procedure in the service book,when you change or move front mounts you change the angle of the torsion bar at the top of the motor,it can twist the belt which makes groaning noice and sometimes a vibration.t track instructions should say loosen the drive belt,thats why gary had to pry motor to get the mount bolts back in,his 09 has xtra tight belt specs.

What you're saying makes perfect sense, except in the section on replacing the front motor mount, the service manual doesn't say anything about loosening the drive belt or re-aligning the engine. If that isn't required for putting in a new mount, why would it be needed for just removing the bolts on the existing one?
