I have a 2000 Mxz 600, which i have just cleaned the "rave" valves. Each valve had about 1/8" of hard oil sludge on it. I haven't been fouling plugs or anything but, the oil pump turned up to the second notch (lots of oil! the dealer did this). The machine has had "ski-doo" oil in it since new... not synthetic just the regular stuff. I dont want to switch to synthetic(even though i know its better). The machine has the stock jets in it, what should I do? turn the oil pump down?
Thanks for the help!
