My bike has always been one that has run hot. especially here in Texas. Moving down the highway I can get it to cool down to normal temp but once I stop at a light or traffic it creeps up to 3/4 of the way or pegs at high. I have to resort to using my fan with a manual button.

Im interested in trying a new thermostat as this weekend I noticed that the temp would peg at 3/4 then shoot down a little. I think my thermostat is maybe sticking a little.

Are there any aftermarket Tstats that can be used? I was reading somewhere that a early 90's dodge truck t-stat would work. Looks like a 92 D50 or so.

What else can I check besides coolant level and air pockets? I'm ot sure what condition the impeller of the pump is in either. Anything I am missing?

Here in Germany the Tstats are often changed against the one of a T12 / T72 Nissan Bluebird (named also Nissan Auster in other Countries) as these open and close around 10 ° C earlier (opening at around 95 ° C, closing again at around 85 ° C)than the Yamaha ones (usually open at around 105 °C and close around 95° C)and will fit in FZRs

Thanks for the info.I thought Yamaha stats on far was 82c

looks like the nissans you mentioned above are what is called the Stanza in the USA. Ill check out thermostats for them


I will try the beck arnley 1430684 160 degree F thermostat
