100 degree heat with an air cooled engine

[vegasdriver_imp]

Took the cb out today. ran a few errands. I knew it was hot but I saw several digital thermometers reading 100 degrees. The bike did great. I did not act up or show anything different than usual. I did get hot myself, at lights. Did not notice any more heat coming off motor, than usual. These things are great. I wish everything else were built as well as these bikes.

Yep, I just returned from a 2.4K trip down to El Cajon, CA. Plenty of 100F temps. I got hot. Bike was flawless. Honda got this one (and others) right.

if temperatures are below 100 fahrenheit on any summer ride for me i figure it is a cold snap

cb1100 runs beautifully under all conditions so far

100 here too today. CB performed flawlessly. Better than me in fact, I developed a slow leak out of every pore

You guys are more adventurous than me . . . I would never ride under such scorching hot conditions. It's just too darn uncomfortable with a helmet on. An OAT of 80F is my limit and even then it is a bit too warm for me.

Btw, I encourage the use of a EOC temperature monitor. I posted about this device in detail in a previous thread. Such a device is quite small and inconspicuous, and very easy to install. It is made by Trail Tech ($43). I am using two of these devices on both of my air cooled bikes, (CB1100 and a Triumph Bonneville). They work very well, informing me of my EOC at all times, (where 250F plus is not uncommon with minimal air flow thru the cooler), as well as the indicated OAT before starting the engine prior the next ride.

dsinned, That EOT monitor comes in 10mm and 7mm. I think your link was for the 10. Thats the one we need?

100 degrees???
Wow, that's more than hot and never gets that hot up here.
I don't even bother to ride if it's in the mid 80's which is not that often.
Here on the Atlantic coast we have cooler ocean breezes to keep us cool, but venture 20 miles inland and it can be very hot.
Like dsinned, even 80 is too hot for me

Popgun, I believe Trail Tech offers three different sensor sizes. I think the the middle size should work best, but to be sure, get the smallest. Where talking about the "size" of a copper bar - attached to a thermalcouple and cable back to the display unit - that wedges in between the fins on the cooler. The "size" is referring to the width of the bar, not the thickness or length, You want the size to be a tight fit, but not so tight that it overly stretches apart the fins inside the cooler. It might even be a good idea to order all three sizes so you can find the ideal size to use. 10mm may be a bit too large for our oil cooler fins.

The sensor comes with tube of silicon rubber compound to fill in the space around the copper bar wedged in between the fins and helps the sensor stay in place as well as insulating it from the "cooling effect" of residual air flow in that location of the cooler.

Instead of pressing the copper bar in between fins, I devised a way to anchor it down "ON TOP" of the flat surface of the cooler. However, it is important even more so to "shield" the sensor in that location from the air stream. Regardless of where you mount it, you want it to be in direct contact with a high temperature surface area of the oil cooler, and which ever way you go, to be well insulated from outside air as much as possible.

If you get this device, please post your observations to the forum. I'm sure some others here will be interested. Thanks!

i would not be able to ride much if that was my limitation lol

Hard to find temperatures like that around here, but when I do (interior of BC, Eastern Washington, etc...) the CB performs perfectly. I've never actually managed to trip the over-temp light on the thing.
