Just a thought.

I was looking at it again yesterday and was thinking of doing one single line from the reservoir to the right side caliper, then piggy-back a line from there to the left side up over the front fender like the modern bike lines are.

This way my Katana will look like a Gixxer...woooooo

Small update.

Today when I came home from work the outside dial thermometer, patio type, said 106F (41C) The specific humidity is unknow, but we have dry heat in the Sacramento Valley.

So I let the Kat idle for 10 minutes with the fans on, on the side stand (if that matters).

The temp gauge needle was juuust over the 200F (95C) mark. Just a smiggen over. After idling for ten minutes the temp went down a little, maybe 5 degrees.

In the picture I started the count at 5:56 on the clock and when I took the picture it is 6:07.

So it is helping a little. And this is at idle, one of the worst running conditions for an oil cooled engine.




Another thing I noticed with the fans running at the stop lights is...how do you like your knees cooked, medium or well done?

Oww, these fans push out a lot of hot air right on the inner knee area.

And a side note, the two LEDs at the bottom of the spedo, the left one (red) is wired to the fans. This way it lights up when it is on and I know it's functioning. In the picture it is being washed out by the sunlight.

Thanks for the update! Would love to see you tell me that the fans kept it below 250 for 30 minutes at idle (well, one could hope).

I remember getting my ankles cooked to a mediterrain brown (literally cooked, literally brown) by my old Honda Shadow when the fans came on at stop lights.

Does make me wonder (kind of idly, not too seriously) if you could run the fans in reverse at stops, so the hot air pushes forward instead

Alright Marc, just for you.

Temp: 92F (33.3C)

Start Time: 6:14 PM

Oil Temp: 300F (149C)

End Time: 6:44 PM

Oil Temp: around 175F (79.5)


This time because of the cooler weather the oil temp went down fairly quickly.










On a side achivement, the bike turned 63,000 miles today. Yaaaa.

Just to make sure I got this straight:
So you came in from a ride with the engine already hot (running at 300F), left it at idle in neutral and it knocked down to 175 in fairly short order?

That is a big-thumbs up in my book and justifies the fans (and turns me into a fan of the fan-mod as well)!

Yes.

I came home from work and the oil temp was at 300F. It went down to 175F quicker today, say 15 minutes, because it was cooler today. But since you wanted a 30 minute test, I left it idling for the full 30 minutes.

Again, it was only about 92F and low humidity. For you, being in Florida, the humidity may change things, temp wise.

Actually, the humidity ought to make it cool better (more heat-capacity in the wet air, better heat conduction to the air due to the moisture content). I guess I'm going to have to schedule this mod in the near future...

Thanks!

Sorry about that!

What's the power-draw on the fans?

No big deal. I let it charge slowly overnight and all is well.


I had to go back to the first page to see what I wrote regarding current draw.

At start-up the two fans drew about 20 amps then settled down to 8 amps for the two fans. I used my multimeter to calculate the current draw.
