billsv11 Posted March 21, 2010 Share Posted March 21, 2010 While checking the valves I notice a deposit on the valve cover the was thick and kind of a light brown color. Any idea what this might indicate? I was thinking condensation and the crankcase not breathing correctly, Link to comment Share on other sites More sharing options...
NakedV Posted March 21, 2010 Share Posted March 21, 2010 While checking the valves I notice a deposit on the valve cover the was thick and kind of a light brown color. Any idea what this might indicate? I was thinking condensation and the crankcase not breathing correctly, If deposit is sludgy it sounds like emulsified oil to me, Quite common I believe if bike is used for short runs as oil never really gets hot enough to drive off any moisture. If the bike is only doing very short runs I'd be tempted to take it out for a good long run then have another look.

billsv11 Posted March 21, 2010 Author Share Posted March 21, 2010 Kinda what i was thinking but just wanted to be sure. Im sure it will run hotter soon as summer comes around in eastern washington and temps get over 100 F =) Link to comment Share on other sites More sharing options...
jrt Posted March 21, 2010 Share Posted March 21, 2010 It is almost certainly oil emulsified with water (condensate). During spring, when it's cold and wet, you'll have to ride long enough to get the engine fully hot (which might be hard to do). Mick is right- the cure is to ride longer/further. Not a bad prescription, eh? Link to comment Share on other sites More sharing options...
billsv11 Posted March 21, 2010 Author Share Posted March 21, 2010 Sounds like a plan to me! I have been having so much fun riding the v11 I havent touched my rc51 in weeks. Link to comment Share on other sites More sharing options...
