    Research this kit before making your purchase. I have the kit on my ski and I believe this engine runs better (in my conditions) with the thermostat installed. If you ride in extremely hot water you may benefit from the R n D kit you mention.

    There are kits available on the forum that utilize the thermostat and improve cooling.

    I believe the tee you mention will bypass the connection between the IC cooling and the engine cooling.
