Hey Don, going to clean out my thermostats before the season starts and was wondering is this a fairly simple thing to do, or should I have my dealer do it? Just don't want to open a can of worms and feel like an idiot if something goes wrong. Thanks Don.
Joe,
Cleaning out the stats is a no brainer. Just make sure you have new gaskets on hand, inspect your discharge hoses and perform a thermostat test on the stats while you've got them out to ensure they are opening properly. One word of caution, <u>DO NOT OVER TIGHTEN THE STAT HOUSINGS</u>.......torque the bolts to spec equally per the manual. I've seen these threads get stripped out before from folks who think they need to use both arms and a foot to tighten the housings down......

DFI motorÂs are going to be a little more of a challenge, can be done but make sure youÂve got a manual to refer to   ..

+1... proper proceedure involves relieving the air pressure (at the port-side rail schrader valve), loosening the rail and sliding it back on it's studs, then replacing thermostat as needed.
O-rings on the injectors MUST BE LUBRICATED with 2-stroke oil (same oil you use in your oil tank) BEFORE sliding the rail back into place.

Note: Thermostat cover bolts are torqued to 100 INCH (yes, that's INCH) lbs.
