Got the 93 r100gs on the road a bit and like it.....New fork bushings , swing arm bearings , steering head bearings and more . She drives nice but makes a lot of noise on the RH side . Valve clearance is at .004 on the intake and .006 on the exhaust . There seems to be a lot of end play in the exhaust rocker though - about a .005 gap . Anybody shimmed ?
