I had my 600ml. service done at 1500ml, and was absolutely appalled by the price! I don't understand why one of the best motor company's would charge to have this done. If my valves need to be adjusted one would think it would be covered under warranty. If i go buy a Honda Civic, a valve adjustment at 600ml. would be covered under manufactures warranty, not $400.00. This bike cost as much as a lower line Civic and the Civic has a better warranty.Thats not right!!!!!!!!!!!!! None the less,, A service manual is on order from Ebay.
