Stock Thermostat

[Harmonicashawn]

Can anyone tell me the stock temp for a first gen VR? I'm thinking that the P.O. put in a colder one. There should be an optimal temp for this motor and I'm thinking that the factory knows best! In my experience with muscle cars- a colder thermostat= less power and higher fuel consumption. Many people (including myself have made this mistake). Thanks--Shawn

I think it is 180 but if the PO put a colder one in, I can understand why. The temp gauge can scare the pee out of you when in traffic.

 

I went through this for a while and the best recommendation I got was to put some tape over the guage.

 

Do some more searching on this (temp thermostat) to dig in this a bit deeper. use some more search keywords related to this as well.

I would simple replace the Anti Freez solution,

 

Install a new Stock Thermo ( Replace Both Gaskets !!! yes there are 2 )

 

( Be very carfull not to Over torque the two bolts that hold the PVC material cover on the thermostate ) If you deform it, it will leak.

 

If its still reading High, I would suspect the Sending Unit, out of calibration.

 

I have never had an overheat problem on my 89, even at 110 deg. outside air temp.

I have cooked my nuts at that outside temp on this bike.

I just replaced the thermostat in my 1983 bike with a automotive style unit.

 

Murray Plus+, P/N 3758, I bought it at O'Reilly parts store.

This was a 180 degree unit.

 

It came with a rubber ring around flange that needed to be removed to fit into housing, otherwise it was a perfect fit.

 

Price was $4.99.
