Thermostats

[Climbmetothemoon]

Do most modern day bikes already have a factory thermostat?

If so do they still need an aftermarket kit installed like a thermo bob or other?


Would a 2 stroke stay warmer under the same conditions than a 4 stoke or not?

Consideringdoing a YZ450FX and Beta 300rr.
So a 4t and a 2t.

Oh and what carb heater is best?

Thanks

I kept digging and found the answers.
So if a mod sees this and wants to delete it that would be great.
Thanks.
