I've got about 10 hours on my raptor now, so I'm going to adjust the valves and change the oil/flush the coolant.
First of all, I plan on running Amsoil engine oil, but I'm not sure what type of coolant to use. Are you guys mostly running automotive coolant or some of the special racing ATV coolants or what?
And for the valves, Yamaha indicates .0039 - .0059 for the intake, and .0059 - .0079 for the exhaust. Are you guys sticking to the stock specs or going tighter?
