Question...has anyone killed an XRL from overheating it? Note: operating conditions are it had the correct oil and amount of oil in it.

If not, then call me what you will, ahhh just ride your pig and don't worry about it.

I saw it coming. Coming from far away I say. It started with a dim little light in the distance. But now, now....it is....

.....an oil thread.:thumbsup:


Yup, thought the same thing myself. My question wasn't so much about cooling/oil. I was more worried about the stock tank being secure enough with the wings off.

With only the one bolt and the two hooks underneath, the tank feels a little loose/wobbly with the wings off. I was wondering if anyone else ran the stock tank with the wings off, and did they feel it was secure enough? Or, was there any way to tie it in to the holes that are there for the wings?

Thanks for any help...

Well, it appears that I tried to kill my XR600 in this manner. I was only partially successful though. Let me elaborate.

I have had two issues that I feel were directly attributable to heat. First I had to replace 2 valve seats. The bike didn't strand me though. What happens is when the aluminum gets too hot it can permanently expand. The seats are a press fit and fail when they are no longer held by the aluminum head. The second issue is with the crankcases. The crank bearing is no longer a press fit. Do some searches and you will find me asking about it in Feb 2006 or so. At that time I was told "don't worry about it" so I just put it back together. It has been running since then with no major problems. I have always worried about it. Over the last year and a half I came to the conclusion that this was caused by overheating. Same process as the valve seats.

If these aircooled bike engines are anything like aircooled airplane engines the actual head temps are a lot higher than the oil temps that you guys are seeing. We are talking as high as 400 or even 450+.

Crazy...reinforcing the fact that XRs are indestructible. At my work I occasionally come across stuff like that with random industrial components (motors, pumps, etc) I usually coordinate the repair of such items so at times I will have conversations with manufactures and they are like "well, you should replace that but if it still running I would leave it alone".

That makes sense. I'm sure the fire side of a frying pan is hotter than the oil inside it.
Air cooled engines have been used for a long time in some pretty harsh environments all over the world (VW, Kubel - pre/post WWII Germany) thanks to their simplicity, reliability and overall low cost/less parts.

cleonard you are right. several weeks ago when i was doing the nitrogen tests(eventually unimpressed with nitrogen), i used my I.R. temp gun after a good hiway ride on the cyl. head... it read 440-460 depending on where i pointed. the higher being close to the exhaust side of the head. the actual head pipe at the head was well over 500.

The XL600R had no wings and ran really hot stock, and it never ever to my knowledge had anyoverheating problems, at least mine did'nt.

For the most part heat (unless VERY VERY extreme) is a slow killer. Heat will kill you engine even at safe temps. the same with electronics. Most times we will never see these differences.
Example:
take a microchip and subject it to a constant 250 degrees 24-7 , say it lasts 35 years.

ok now take that same microchip and subject it to a constant 200 degrees 24-7 now it lasts 32 years.

This is just an example. The more heat you have the more wear it will make on you engine, it is a killer over time and unless an extreme event you will not see the difference.

Now heat can and will destroy you oil much faster. Oil is cheap, change it often and save some $$ and dont buy a motorcycle specific oil.

OK I know this is an old thread but you guys still think its safe to take the shrouds off for good?

I had no problems. If you think about it, the oversize plastic tanks eliminate use of the wings.

I have no wings, broke one clean off during a harescramble. No heat problems....I also drilled about 2 dozen holes in the front fender(rear part) to let air flow thru. I also run Rotella 15w-50.

not to hijack the thread but how did you do in the harescramble? i know new england is some tehnical riding!

I use an acerbis XR400 front fender = shorter in the back than stock to let a bit more air in and looks better then the big mutha flappa fender that comes stock.

If that 5psi changes the attitude of the bike enough, that's entirely plausible with the stock XRL fender!

The 606 as long as you add 5 psi to the forks and use the purple power band with it.
