i JUST GOT DONE CHANGING MY OIL IN MY DS650 AND NOTICED THAT IT WAS VERY THIN AND HAD A GASY SMELL TO IT. WAS WONDERING IF THIS HAS HAPPENED TO ANYONE ELSE AND WHAT WOULD CAUSE IT? I SHUT MY GAS OFF WHEN I TRAILER IT. ANY HELP WOULD BE GREAT.

 

When my DS was new the choke was sticky and a couple of times I didn't get it pushed all the way back in. I changed elevation 5000ft so I thought it was just running rich. It did'nt take long to dilute the oil with gas. You have a two stage choke, pull it out and make sure it clicks in twice. Hope that helps.
