DipStick Temperature '86 XL600R

12 posts in this topic

When Im cruising on my XL600R wirh a speed of about 110 km/h (68.35057631963215 M/H thanks to covert.exe :thumbsup: " the temp on the dipstick reads about 110 D/Celcius (230 F). Is this too High? Outsite temperature was about 10 Degrees Celcius (50 F).

What will happen in the summer (Well that would be a Dutch summer, so average outside temp about 20 Celcius)

I Feel it's a bit high, cold this bee from running a litte lean? (Exhaust uncorked, Twin air filter, Box still snorkeled)

Well, this bullet-proof air-cooled motor hasn't changed much in the last 24 years so I wouldn't be too concerned. The carbs are set lean from the factory so ensuring it's properly jetted is always recommended. Do a spark plug check for that.

A quick, cheap and easy mod to allow more air over the cylinder is to cut the front fender. Cut off a few centimeters of the front of the front fender, a few centimeters off of the back portion, and drill vent holes or cut slots in the back to increase the airflow to the frame and motor. Drops temps anywhere between 5 - 15F degrees at high speeds.

Other than that you can install an XR400 oil cooler, but that isn't absolutely necessary. The dry-sump oil-in-frame design does this already.

I am running about 200 degrees, at 60 MPH - around 48 - 50 degrees outside. Uncorked /rejetted XR650L also running an aftermarket XR400 front fender (acerbis) and I have removed the tank wings (elephant ears)

I'm surprised they would state that high of a temp, but Xrs Only aint that sharp, anyway ... petroleum based oil starts breaking down at 300 degrees, and if you search oil temps, you will see a lot of posts, most averaging about 220-270, if memory serves me right ... :thumbsup:

Its all the worse they'd say that since the oil in the hottest parts of the engine is prob. a fair bit hotter than the oil in the resevoir.

I read ceramic coating the header, or wrapping it, is good for a few degrees. I wrapped my header, but I don't have a temp guage to see if it did any good. If I had it to do over again, I would have just done the ceramic coating. The wrap is getting unsightly, and it stinks when it gets hot.
