A friend of mine has just got him self a RSV 05 track bike (4k on the clock) which has never been on the road- always been a track bike. Standard engine, pc3, renegade and full system. Over the winter he is getting it ready for next season. Over the weekend he stripped it down and couldn't beleave the condition the engine was in- not much wear at all and this is its first refresh. He might not even refresh it now. Anyone on here race one? How often do you refresh?
