I use TFOG Wheelsports in Lakewood.

I'had them service my T120 and ST#. Last year when my tranny failed to shift on the T120, they replaced the shift shaft and it works great now.
But, I have to tell you I'm now committed more than ever to doing my own work. Just did the 12K work on my R1200R, including test valve clearance, change oil in engine and final drive, drain and bleed brakes incl ABS motor, repalce spark plugs and air filter. Took 2 days but worth it. Watch Youtube, talk to Capt Bob and buy the tools. No one will ever care more for your bike than you do.
