SM states below as prescribed PM schedule for "normal" use, not severe conditions. I push mine very hard, back road racing with average RPM's of 7000-9000 with moments of 10000. I suppose I should ask how folks service the GS when they track every weekend, and what intervals I should follow for:

- tappet clearance (inspect once every 3500)

- oil/filter change (change once every 3500)

- carb cleaning (not specified)
