I have a new GSX-R750 that I can't seem to ride enough (meaning I have trouble finding the time to ride it). I have only 500 km or so on it since taking delivery in late June. The first service is meant to happen at 1000 km, which includes oil/filter, bolt tightening and miscellaneous checks. When I do switch to synthetic, it will be Amsoil MCF 10w40 with the Amsoil filter; I'm just debating whether to do the switch at the first service, or to get clean dino in there for a little longer. Thoughts?
