RSV2 - Doubt on Cooling System

diabolico · Jul 23, 2011

Hi... Can anyone tell me if there are any bad consequences if i remove the thermostat valve? beside taking more time to put the engine at the right temperature does it make any diference? I know this will sound stupid but i'm trying to give a "clean" look to the area around the engine and removing that would help. If there are other solutions like adapt other thermostat in other place,i would love to receive advices.
Thanks...

best ask Griff mate..aka fusebox..he'll tell you the truth

are you building a tuono naked bike or something else lkike a cafe racer sort of thing?

Removing the thermostat is not something i really wanna do,but if i can do something to hide it or remove would be good.

apart from the obvious (it will take the engine longer to reach optimum operating temperature)
it can also effect the flow of water into and through the rads, this can cause the engine to run cool or could cause it to run hot as the water isn't spending long enough in the rads.

maybe someone has run a mille without one and can report no negative effects, whats the one like on a Tuono i am guessing Aprilia managed to hide it.

The thermostat is there to help keep the coolant temperature as stable as possible. Without it the engine will take longer to get warm, and the final coolant temperature will then be dependant on the ambient temperature, and could end up with the engine running too cold, and with the temperature cycling up and down more which is not good news for the engine. Removal of thermostat can also affect the coolant flow through the head, so it's possible to get local overheating even though the engine is running cooler than normal. All in all, a poor idea to remove it for road use. Aprilia/Rotax didn't fit a thermostat for their own amusement.

can you not modify the pipework to hide it somewhere else?

that's what i'm going to do... i didnt wanted to remove it,but the true is that would simplify a lot the work

if the only consequence was to take a little longer to reach the perfect temperature it wouldnt bother me.but if brings bad consequences it must stay.

yep thats the best idea i think..they spend millions on research ..so they must be right..lol..be a bit creative with the pipework sur eit would look ok
