2005 S4R thermostat question

[DucHead]

Gee-whiz - it's been a while since I posted.  I'm still riding my Monster and a bevy of Suzukis. 

I read through a few thermostat threads on the board, but didn't see exactly what I was searching for... dMy Monster coolant temp gets quite high (up to 200°F while riding), and I thought perhaps the thermostat shit the bed. So I drained the coolant and removed the thermostat and it opens at ~165°F. I cycled it a few times and it seems to be working although the opening temp seems a little high. I'm going to flush the system with 1:1 vinegar:DI water once the new silicone hose kit arrives and I re-assemble everything.

I believe that the two sensors that connect to the unions are to trigger the radiator fans, so I don't think that could be a problem.

Any thoughts?

IIRC, one is the fan switch (on/off through a relay) and the other sends the temp (variable voltage signal) to the ecu.

I might not have a ton of relevant information to add, but my track bike, that has no fan, runs at 180 while moving. No clue about the thermostat condition.

Thanks, gents!
