G'day All, I recently purchased a 2008 Yamaha R6 with 13,600km. The service book has been stamped at 1000km, 2300km and the last service was at 7500km. The last service is somewhat questionable as it was not in the book when I inspected the bike before the sale. The owner claimed it has been serviced with a mechanic and that he could get the booked stamped, which he did before the sale. After the sale he told me that it is probably due for the next service soon. I checked the service intervals in the manual and they are set at 1000, 10,000 and then 20,000. I'm not sure exactly what happened with the last service, maybe he did a minor service himself and had a friend that works a mechanic sign off on it. Do you guys think I should get it in for a service before 20,000km? I called two places for a quote on the service and it seems to be around $300-$350 for 2.5 hours labour, new spark plugs, oil, break fluid and other checks. Does this sound reasonable?
