"HOT" 836
« on: June 18, 2010, 05:43:19 PM »
  After much headache I think I've got my carbs about right. Plugs are lookn good. I'm just super paranoid of doing damage to this motor. To much money invested to burn it up.
   When I got home from about a 1 hr. ride this evening I pulled the dipstick and dropped in a meat thermometer. High tech I know but thats all I have. Pegged the needle past 200 F quick. The thermometer only goes to 200 so I'm not sure exactly what the temp was, looked like a good 250.
   Not going to even get into oil. I'm using good stuff. Maybe I'm not getting a accurate reading like this. The bike did'nt "feel" to hot. If I could get some average temps that would be great. Did the search got like 33 pages. Just lookn for some fresh input.
  So I ran about 1 hr. like I said, not real hard but certainly not babying it. Outside temp about 85 deg. Thanks for any input.

Over 200 is fine, the oil should get above 212 to boil off any water in there. I would expect the oil to get up to 240 at least, from what I've read 260 is about the maximum temperature you should get to. Engine oil temperature gauges commonly go to at least 300F. JC Whitney has an electrical one on sale now for $3.18. Or dip a candy/deep fat thermometer in the tank. The tank reading should be quite accurate if you measure right after a ride, in my experience the hottest oil temp I get is during a hot day highway ride regardless of the fact there's lots of cooling air. If I had a gauge I would know for sure I guess. I try and avoid stop and go driving on hot days but I expect the oil and engine would get really hot then. I used temperature indicating stickers on my oil cooler, these are a "one shot deal" that change colour permanently when the rated temperature is reached. I made 245 on a highway run.

Agreed, a quick google on operating oil temps puts the avg for an air cooled engine at 240deg F.

Gonna need a link to that one, I'm searching JCW now and I can't find it!
