Soooo, the valve seats and clearances settle after breaking in and do not change so often after that. Approximately how many engine hours do you guys reckon the majority of the seating is done at which the clearances will not be reduced further?? Based on a hard riding style somewhere in between cruising and flat out racing?? Any educated guesses??
