do you guys still use farenheit, get with the times

i would assume this is after riding it? or just starting it. my pipes, right as they get out of the head. they read 200
after 5 Min's and clime from there. after a good ride they get as high as 400 and level off

After a 20 minute ride.

lean it out and go for a night ride and the ex pipe will have a purdy orange glow

Wow... That low? I would have expected in the 350-400 degree range. Then again, it does need excess capacity for idling. I wonder what the cylinder head temperature stabilizes at while idling for extended periods...

about an inch below the dipstick (towards the rear of the bike) on the horizontal section , I've got a surface temp gauge. I take a quick glance down there during a ride from time to time to see how hot things get in different situations, like idle, cruising at city speeds, cruising on the backroads/highways, and pushing it aggresively (almost like you hate). In that order, and putting on my fahrenheit hat (man that's hard

), I get ranges like 171-185, 149-158, 149-158, 171-193. depends a little on the outside temp, but the ranges are about right for what I see.

originally I put it on, not necessarily looking for absolute accuracy (didn't hook up an oil temp gauge, but wanted some kind of feedback for engine temps), but looking more for changes per given situation, which it does just fine. glad to see others are comparing surface temps for future reference. good idea scratch!

Being a modern Aussie who uses the metric system, I have no idea what this actually relates to in Celsius so here is the conversions.

Top front engine fin: 85 'C
Sparkplug fin: 88 'C
Valve cover: 69 'C
Exhaust pipe, near head: 75 'C
Exhaust pipe mounting flange: 82 'C
Dipstick: 72 'C
Intake manifold: 85 'C
Rubber carb boot: 66 'C
Carb body: 46 'C
Floatbowl: 49 'C
Starter motor cover: 73 'C
Camchain tensioner: 75 'C
Crankcase @ base of cylinder: 71 'C
Oil filter cover 66 'C

Now I dig it!
Thanks! And only took a year to convert !

dont blame us for not using the metric system. Its those damn britts that imparted their wisdom on us back in the colonial days. Then as a sick joke switched over with the rest of the world leaving all by our lonesome to bask in our ignorance.
