The 996 is probably showing coolant temperature as opposed to oil temperature in the Monster. But I'm curious too. Never had an air-cooled bike that told me how hot the oil was before, and not sure I really want to know that bit of info.

I've seen 230 on my 620, and I don't have an oil cooler even. The VFR has gotten up to the low 220's in Arizona, but that's water-cooled.

So what can we expect in SoCal next summer?

oil too cold is more of a problem than oil that is a little too hot. even in my car, if pushing on a hot day, oil temps of 260 will be reached.

ride and enjoy!

I've hit oil temperatures of 240+ a couple times, but when that happened there was a definite loss of power. Supposedly that's well within the operating range of the bike. Also, you should see the temp guage say "HI" before you can do any damage.

Some of the air-cooled Monsters had defective oil temperature sensors, but it seemed to be confined to a batch of 620's.

A couple months back there were some posts on the oil temp reading 150 or so, immediately after turning the key on after the bike sat all night. IIRC, all of those folks got the sensors replaced under warranty, and I haven't read any more posts on it.

Oil temp over 212 is good, so it'll evaporate off any water from combustion blowby or crankcase condensation. For petroleum oil, I recall seeing that 250 or so is about the max that the manufacturers recommend.

Some of our folks here race their 620's, and have reported oil temps up around 300. From what I've seen published, that's really hard on petroleum oil.

300? Sounds like a good time to switch to synthetic! Opps here goes another thread!

;D ;D ;D

Just curious on the other side, lately with the cool temps its been hard to get the oil temp on my 750 above 180 without some lower gears and hard riding. How well do the oil cooler covers restrict air flow across the cooler? I do not feel like making a custom part. I think Rizoma makes a trick part.
