Re: Oil Temp

[Bob Hadden <kbhadden@xxxxxxxxxxx>]

Tom,  I'm pretty sure the RS doesn't have a thermostat.  This is 
illustrated in the maintenance literature I have, and there is no sign 
of one on the bike.  My understanding is that the t-stat is a separate 
assembly behind the cooler with hoses coming and going etc.  There is 
none of that on my bike.

Are you saying there is a t-stat inside the engine?
