JerryK Posted July 14, 2014 Share #1 Posted July 14, 2014 A couple months ago I had my mechanic do valve cover gaskets,carb boots and adjust valves. All that work is fine and covers aren't leaking. But I have an oil leak that follows the kickstand and exhaust and is coating the rear wheel! It's down low for sure. My mechanic thinks it's the Stator wire Gromlet where it goes through the cases. Is that possible? Link to comment Share on other sites More sharing options...
Neil86 Posted July 14, 2014 Share #2 Posted July 14, 2014 You might check the center cover on the stator cover and the timing plug on that cover as typically both are removed to rotate engine during the valve setting procedure. Link to comment Share on other sites More sharing options...
djh3 Posted July 14, 2014 Share #3 Posted July 14, 2014 Over full on oil possibly. It will push it out the breather hoses. usually thats up by leg fairings though. Link to comment Share on other sites More sharing options...
bongobobny Posted July 14, 2014 Share #4 Posted July 14, 2014 Besides the above, yes that is the most likely cause for the leakage you describe... Link to comment Share on other sites More sharing options...
V7Goose Posted July 15, 2014 Share #5 Posted July 15, 2014 Over full on oil possibly. It will push it out the breather hoses. usually thats up by leg fairings though. This is ALMOST correct - yes the problem is too much oil, which causes a lot of it to be blown out the crankcase vent (this is covered in great detail in many older threads). However, this oil is never up front. the vent hoses are two of the cluster that hangs down below the battery just above the tip of the side stand. the main oil is coming from the one that connects to the left side air plenum above carb #1.

Lassesand Posted July 15, 2014 Share #6 Posted July 15, 2014 I have had problems with the stator wire grommet. Took a couple attempts with a lot if cleaning an silicone sealer but I stopped the leak! It was after I replaced the old stator (burnt) with a new. Sent from my iPad using Tapatalk Link to comment Share on other sites More sharing options...
JerryK Posted July 15, 2014 Author Share #7 Posted July 15, 2014 It's not too full of oil and continues to leak. I have confidence in my mechanic and you guys just confirmed what he's thinking. I HATE HAVING A YAMAHA LEAKING OIL! Thanks for the help! Link to comment Share on other sites More sharing options...
