i have one that looks just like yours.mine dose the same thing.it used to be worse.till i changed the valve stems in rocker switches.now they will hold up for a couple of days.i am goin to drain oil out of front and back shocks and fill with new oil and see if that helps.
Thank you for the reply where did you get the replacement parts for and can I pick them up at an auto shop supply store. My avitar is my bike that I drive every day as long as there is no snow on the road I also drive when the temp out side is below freezing if there is no ice. Take care Ken
if you have a napa store take one of the valves with you.they will be valves for air cond.i put all 3 in.hope this helps you. as the weather is a little bad here i have taken valve covers off and getting new gaskets.and shifter seal had small leaks.want it all done.before ridding season:waving::waving:
