Finally got all of my clutching issues fixed! Today was the first ride I had went out on with my 2000 kodiak 400. Before loading it up last night I went through it a bit and checked the oil and such. Well I guess after cleaning off my oil dipstick and inserting it to check level I scrubbed the side of the crankcase and got some oil on the dipstick. So I thought I was good ok the oil. After a couple hours of riding today all of a sudden it shut down and acted like something locked up. Ended up put a whole 2 quarts of oil in it, IT WAS EMPTY! couple of guys I was riding with had a couple of quarts of Rotella that I bummed. Convinced that it was already shot, and there was no hope I cranked it for a few seconds and it started, but was sounding pretty rough ( I was thoroughly convinced I spun a bearing). After shutting it down and coming to terms that the damage had already been done, and I might as well try to ride it back to the truck, we took off again. After 10 minutes or so of riding, the engine smoothed back out (not completely, but WAY better). Rode probably another 4 or 5 hours. And not easy riding either. It ran like a champ, and never noticed any loss of power. With saying all that I have a question and statement to make. First the question: has anyone ever ran any of the Lucas oil treatment in their wet clutch equipped yamagata? And for my statement: Grizzlys and Kodiaks are some tough sons of b#####s!! Definitely feel like I learned a valuable lesson today… The hard way.
