[QUOTE="nephron, post: 233571, member: 23759"] Ouch, all [I]that[/I] & the answer is elementary (to the original question, that is). Before you'd R&D a product for a vehicle, wouldn't you want to make sure most, if not all, the vehicles would [I]need[/I] that product? Now, try to imagine bean counters at Honda thinking about the "breadth of application" of a thermostat on a dirtbike.:think How many bike builders think the majority of their bikes are going to run flat out in 5th gear across a wide open snowy & frozen plain at 30 degrees F? I guess KTM does.:) On a side note, in the auto industry, a thermostat's PRIMARY function is not to make the motor run better, or allow "cleaner" emissions. They were originally designed to optimize warm-up characteristics & get the motor up to 180 ASAP, & then leave it there [I]for purposes of reducing wear[/I] . Furthermore, in this day & age, with everything FI, one wouldn't need a Thermostat to assist in proper fuel atomization since the temp would directly translate into a change in MAP & therefore followed by appropriate fuel curve adjustments. I wonder if any of the Thumpers have thermostats, since valves/guides/seats are particularly sensitive to extremes in temperature. Guys & gals?:think [/QUOTE]
