So I take my new shiny 05YZ250 out to do a nice easy break in ride today. Do 30 minute warm up. Let her sit then I did about 20 semi fast but not hard laps on the track (about 23 miles or so). Loving the bike working welll....except it starts leaking coolant. So I pack up and come home, wash it up, and add a little over a 1/4 quart of fluid. Start it up and look to see the base gasket puking coolant out below the exhaust flange. I havent even ran a tank of gas through it yet. Im friggin pissed, and its a good thing I wasnt 50 miles into a desert race. Ill warranty the repair, but this crap shouldnt happen on a Yamaha. KTM maybe, but not Yamaha.
