Am I overheating?

Postby Quarteg » Mon May 23, 2016 5:04 pm



Hey guys, it's been a while. If you recall I created the video on how to add the aftermarket alternator conversion kit to the 1986 GL1200 Aspencade. (Which I might add is flip'n awesome!) While doing the conversion, I never once thought about changing the thermostat.

As the weather is getting nicer here in Wisconsin, on Sunday (yesterday), I took the bike for a nice hour and half long ride. There are parts where it was stop and go, but my last stop, before hitting the hwy, I noticed my temp bars were almost to the top. I think there were 2 bars left (putting me up to 7 or 8 bars) to fill at which point it would have been (I'm assuming) over heating.

The tricky part is, I don't know if the fan kicked in, or because I was going 65 down the hwy, but the gauge eventually went back to 5 bars. I checked the fluid when I got to my destination, and it was all there, and because I did that conversion 2 years ago, it is still new.

So my million dollar question is this, how high can the bars get before I have to really worry?

I don't recall any other over heating issues on the rest of my trip, even though it was in the low 80's.

Of course it is cheaper to replace the thermostat than it is to replace a seized engine, but I really don't want to spend another 10 hours or so, ripping the bike apart to replace something I may not need to.

Thoughts?

First I would confirm the fan is coming on. You need it. Go for a ride or site and let warm up. See if the fan kicks on. Mine comes on at about 7 bars. You can hear the fan when it gets up that high. Turn the engine off and turn the key back on ( dont start) you can hear it roaring if working. just my .02 worth.

I'll try that tomorrow or Wednesday. I know I thought I killed the fan when I did the alternator conversion, but I remember now that I had to wait for the bike to get pretty hot before it would kick in. That's why I wasn't sure if the fan kicked in right as I was hitting the hwy or if the hwy speed was cooling the bike.

Thanks for the idea.

I'll keep everyone posted as i know more.

If you look carefully at an aspy dash , there is a range for acceptable temp ( from 4 bars to 8 bars ?? ) and I was told that anywhere in that range is sorta " ok ". All cooling systems in cars and bikes operate over a " range ".

At the top level ( 8 or 9 ? ) the fan should come on ... do the test with engine off, and key on ... should hear fan ...
or...
add a Toggle switch and a LED to over ride the thermal switch , and " see " when the fan is "on "

take care

My '85 LTD generally shows 4 bars on the higher when one up, and 5 bars when two up. City driving and on course, generally up to 6 bars, but not any higher and the fan does come on.

Ran bike yesterday, bars went up, fan kicked in, and bars stayed where they were for a couple minutes. Guess I had nothing to worry about.

Thanks.
