Change the oil, leave the coolant alone (provided it is at the correct level). If it is low (from having boiled out the vent) then add DISTILLED water to correct. There are folks who would tell you to add coolant to correct. Chances are you do not have the same stuff that is already in there so it would be better to just dilute it a little rather than introduce unknown chemicals to the brew. The wrong coolant in an aluminum engine can cause a lot of trouble. I use Honda's coolant cut with distilled water %50. I dare you to ask the list what oil to use! Elden Carl runs a aux. fan switch on his bike, I am in the process of doing the same. The KLR has a rather tolerant window for engine temp. but why push it? Morgan

  What is oil thermal breakdown and how does it happen? My guess is that when the oil gets too hot once, it looses it's effectivness forever. Is this correct? In my previous post, I described how I was caught in traffic in 90 plus degree heat and my fan broke while the temperatue guage was at max. Should I change my oil? Could this also be true of coolant; should I flush and change it too? Thanks in advance, Brian Shepard Philadelphia PA A13   [b]    Thermal breakdown would be rare in a motorcycle with the oils we now have, except in the cases of overheating and if you had a turbocharger, which will coke oil in the bearings if you don`t allow a cool down before shutting down.

I'm almost certain it did NOT boil over. No paint bubbling that I can see. I think I'm okay. I'm going to change the oil this afternoon. Thanks for the reply. I think I just won't ride it from now on if its above 90 degrees outside.   -Brian Shepard  Philadelphia PA  A13

I arnt no roket sientist, but I did hear from so bro's that the oil wears out quickest from being sheared, where them funny lookin lil molecules get sawed in half, like, then keep gettin sawed in half, like by the trannsmixer, you know, it has them gears what saws the moleclues like no other place inside the engine.

Brian, I wouldn't worry about riding in 90F or higher temps with your manual fan switch. Just turn the fan on at about 1/4-1/2 scale on temp gauge and leave it on for your whole commute. I live in Phoenix where it's already over 90F almost every day and I stop-and-go commute for 45 minutes one way. Temp never goes above the 1/2 scale range with fan always running. That little fan makes a big difference! Barry '91 KLR 650

Actually I'm a little concerned about the fan switch mod I did. As I said in my post, I hooked up the fan directly to the European Running lights leads. Although I didn't measure any volts or Amps, the Amps are less from the European Running Lights leads than the normal Fan connection. I know because the fan doesn't turn as fast as it did. Before the mod, I could always hear the fan turn on over the noise of the engine. Now I can't hear it, but it is on and turning fast just not as fast as original connection. It is indeed working as my temp gauge never goes past half-way, but I think I'll do the other variant of the fan switch mod that taps into the original power source, but bypassing all the relay switch stuff. Thanks for the reply. Actually I'm embarrassed to say that I'm bringing my bike in for an oil change and to fix the fan and put it back stock. My fan switch mod wire bundle will be carried with me at all times in the event the fan breaks again, I'll just wip out my wire bundle and hook the fan up to the running lights. Its a good thing to have during long trips on hot days just in case. I'd be interested in hearing from any electrical wizards out there on my choice of European Running Lights source for powering the fan. I'm well versed in electronics, but messing with automotive electronics can be risky. Sometimes only God knows what & why the engineers did what they did on these vehicles regarding the electronics. I'm worried that I might be compromising the entire electrical system of my bike, but all seems to be fine. No strange noises or sounds and all the lights work okay, but you never know. -Brian Shepard Philadelphia PA A13 -----Original Message----- From: Barry Mcpherron [mailto:r40286@...] Sent: Tuesday, May 16, 2000 12:02 PM To: Shepard,Brian Cc: 'KLR List' Subject: Re: [DSN_klr650] Oil thermal breakdown Brian, I wouldn't worry about riding in 90F or higher temps with your manual fan switch.

The motor doesn't stop dead, it will still be turning over a bit and if the ignition comes back on after the momentary off then it keep on running.

No idea, but it appears to have been designed for a completely different ignition system. Mister_T
