Bike was ripping thru oil, 150-170 ml per ride. Installed new big bore 478 cylinder, piston, rings, valve seals, new intake valves & new timing chain. Old cylinder did not look that bad, could see some wear on nickasil. Still went thru 150ml per ride:banghead:, but then after about 3 rides it went down to about 60ml oil loss per ride:confused:. Did rings seat better? Then I started going thru oil again 150ml +. Found oil leak @ front sprocket counter shaft seal. Replaced w/new. Still go thru 60ml+ per ride. The harder I ride the more oil I go thru. Any suggestions? Bike has ton of hours, runs strong, starts first kick. What is OK oil loss? 30ml? Typical ride 45m high country single track.
