[QUOTE="Uchytil, post: 1120509, member: 43803"] Of the two engines it sounds like two different problems. Getting back to basics; did the 1st bike get warmed up before loading, i.e. to prevent cold seizure? In the second bike; is the coolant level correct and is the pump working, i.e. to prevent overheat? Since the jetting is stock, I would say the gas&oil mix is not a concern. I run the same mix in a wide variety of Hondas & Yamahas. Never had a problem like that with low hours. WOT, sand, heavy rider, could be causitive. The airfilter clean and not oiled too heavily? Correct sparkplug heat range? Chain not too tight? Go back to the basics. Let us know what you find. You must be at Lejune, maybe CPoint...I may be going back to that area soon. [/QUOTE]
