thermostat in shee...

I think the original poster was running his banshee on the street,which would explain why he had trouble keeping the engine temperature at optimal operating level.

 

For trail bikes or duners,its not necessary.

well, belive it or not, with too high of flow, cooling efficiency to in both the cylinders and radiator drops dramatically. i do not have the data/calculations to back this up either, just real-world experience from both snomobiles and dirt track racing. in the sno-machines, people would just ditch the thermostat for both flow or sticking, and those who did not install a restrictor/washer in it's place would enevitably blow a head gasket, or melt a piston, no matter how you warmmed it up, and the coolant never overheated untill it stoped. on the cars, there was all kinds of cooling issues both durring and after the heat. now, as for the cold climates(sub-zero), i can tell you that i had really bad overheating/boil-over conditions, even with brand new conventional (green) coolant at any safe ratio. simply switching to dexcool solved this problem in exact circumstances, due to the tranfer properties of the chemical itself. this showed the effect of extreme teperature differences inhibiting thermal transfer. i would not, however run a thermostat in a banshee unless you have already greatly increased the flow rate, and only do so with some sort of partial bypass installed as well....
