Thermal images of Hawk engine
Took these for fun after a ride today. Anyone know what the normal temp should be? Ambient is about 90 today.
Left side oil screen bolt area Left side Stator. Left side head Right side head + exhaust

Seems hot to me. I hope you are running synthetic 20-50 oil.

I am running synthetic 20w-50. I assume there isn't anything you can do about engine temps on an air cooled engine. Assuming it isn't caked in mud.

And people are arguing the need for an oil cooler? I didn't have a Fleer but my laser heat gun recorded similar temps.....

But don't forget, your standing still. Set up a ventilator fan for a representation of true operating Temps.
Cool demo, thanks

The engine was off, I pulled into my driveway and shut it down and took the pictures within a minute of shutting it off. I am sure even in the minute affected the temp but good enough for me.

Traditionally, when an engines oil ran too hot we put in a bigger oil tank, one of the good features of dry sump engines. But this engine is wet sump, and only has about a 1 1/4 quart oil capacity. That is barely enough oil capacity to get the job done. So the only solution that comes to mind is synthetic oil, which does not break down as easily at high temperatures.

Now everyone knows (one of the reasons) why one of the first things I did before starting the engine for the first time... was to put synthetic oil in that (non oil cooler just) Air Cooled Engine/Wet Clutch Transmission design

On my
Y rocket a db07a I routinely register 300+°F on my commutes and have never had issues... on a 90° day sitting at a stoplight will yield around a 365° head temp, measured right near the exhaust where my temp probe for my trail tech vector dash is. On my ke100 I have seen just shy of 400° at the plug...so I would say you aren't riding as hard as me....LOL then again extended periods of 60mph and wide open throttle to keep up with traffic flow is tough on a bike... I use a 1000 MI oil change interval on it though so I don't worry too much... |

365 degrees, no vapors are going to be hanging around in that crankcase like you say, these little motors are incredible

I think we both know I was talking about one of these for the 'oil cooler'
http://www.chinariders.net/showthread.php?t=16941 So like I said "non oil cooler, just air cooled engine"
