[dsn_klr650] oil thermal breakdown
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?

[dsn_klr650] oil thermal breakdown
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. In your case, if you did overheat it, I would definitely change the oil, get a 100 or so miles on it and change it again. In case you burned some oil[/b] [b]you want to clean the residue out. As far as the coolant goes, I would test it and if it looks okay, leave it alone. What did the plug look like? Have you noticed if any of the paint bubbled anywhere on the engine?[/b] [b]Skip[/b]

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

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!

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.
