[QUOTE="DKT735, post: 151882, member: 17690"] FMX: Did you check the jetting when you ran the synthetic oil? From my perspective the best thing to do for a sticky powervalve is to clean it. Unless the black goo thats inside the power valve cover is really bad, carbon that may accumulate on the valves themselves will cause them to stick. Pull it apart and clean it. If you think semi-synthetic works for you that's great. It's your bike and you pay the repair bills. Use what ever you like and have fun. I don't want to put words in Rich's mouth but a blanket statement of one oil type is better than another without stating the characteristics that make the oil better is the flaw in your logic. What do you think are some of the jobs oil is supposed to do? Most oils will do a good job of lubrication. But in a 2 stroke it must also burn clean and not inhibit the combustion process. I've learned alot by chatting with the folks at Precision Automotive Research. Email them if you want to be enlightened. If your powervalve is gummed up, the combustion process in your engine is not happening the way it should. The symptoms you describe to base your decision on which oil is better could be solved by jetting the bike. Simply stating that it is the oil's fault may be over simplification. [/QUOTE]
