Hot Days

[Sand Burr]

Was asked an interesting question last night and did'nt have a great answer for it.

On a very hot day; above 85; if you are driving an older wheeler that is AIR cooled in lets say tall grass at low speeds what is happening to the motor besides the obvious of running hot. Is there an extreme risk of Burning the motor down?

Think about air-cooled motocross running in 90-100-degree days. Sure they're moving faster but as long as some air is passing the heads (it must be if you're moving forward) it's cooling sufficiently.

Dave,
By the number of posts on this it either is not a problem or nobody thinks of driving them when its that hot?

Sand Burr...

I think alot of us don't have the answer.

When riding my 3 wheelers around I never used to think about it that much. Now that the the 4 wheeler (liquid cooled) is around and I get the constant reminder of engine heat from the sound of the fan kicking on.. temp is always on my mind.

I have never knowingly caused any engine damage from running slow speeds when its hot out.. coincidently.. I always seem to be on trails with alot of water when its hot out(trails I avoid when cold so I dont freeze).

I guess I'll have an answer in a couple weeks when I rebuild the 3 wheeler.

That is why it popped into my mind! I was doing some scouting two weekends ago and was riding the 500 listening to the fan kick on and off and a friend had an older air cooled machine and it just made me think Hmmmmmm whats going on in there?

Also, does the friend's wheeler have an oil-cooler? And, how many cc's? Some more questions that play into the cooling game too.
On some of those really hot days, and working to get through tall grass, I'm surprised my lawn mower hasn't went kaput. Kind of makes ya wonder....
