I agree with the amp draw--I am going to have top get an extra fan assembly and look into the possibilty of rigging a brushless motor up to it. The brushless motor would draw less amps, but a motor that size would no doubt be very expensive.
Funny, mine does.

I think everything is relative.. as to where you live.
During July and August in the South with 90 to 100+ degrees riding I became concerned when stopped in a traffic jam or slow going through a construction zone (and yes they have the crews out in force during the summer).
I watched the temp gauge creep up, could hear the fan going and then it was a toss up as to which would happen first
1. The bike would reach the red zone and have to be pulled over and let cool
2. The battery would be drained from the discharge
3. I'd run out of gas by keeping the revs up to charge the battery to keep the fan going to try and cool the bike.

So... I've done the following..
First I used Water wetter in the coolant to help cool the bike. This helped.
Then I switched to Engine Ice coolant and this also helped. Comparible with water wetter, I think one or the other is fine.
I have a volt meter onthe bike so I can keep an eye on the discharge if stuck in traffic. AND.. I have an 8 gallon auxillary tank in the sidecar so as long as I'm fueled up I can wait out the worse traffic stoppers. (if nothing's moving I just shut down and polish the bike while I wait.

Ironman-
So on a 90 degree or hotter day your fan comes on while your sitting still or idling in traffic when the temp goes up and it comes back down to normal temp right away with no fears of possibly overheating?
I want your bike!

The fan cycles on and off. So far it hasn't worried me about overheating but maybe I don't have to sit in traffic as often as you do. And no, you can't have my bike.

The whole discussion makes me realize that I need to flush out the system this summer. I'm getting the feeling that the electrical system may not be the only thing with marginal capacity.

I have a major 2 lane highway I have to travel back and forth to work that is heavily traveled--too many vehicles and not enough blacktop. When I get to the other major highway intersections I have to wait forever at red lights and on really hot days the fan kicks in and cycles like it should, but the temp doesn't go back to normal, it comes close but it's still a little on the hot side, until I get thru the light and pick up speed; then it returns to normal temp's
I'll have to try Dianna's Engine Ice coolant product she mentioned.

Hey Dianna,

Is water wetter a replacement for the coolant or just something you add to the existing coolant? I searched it on google but saw results for both types. Think I might try some of this stuff since you say it did help. Thanks

Water Wetter by Redline is an additive. Engine Ice is a premixed Coolant
Water Wetter, about $6 and will treat several bikes.
Engine Ice, about $18 for a half gallon (enough for one bike)

Run cooler Muzzys fan blade Ninja 750 ZL900 Vulcan H5 Item number: 180115307184

Why buy that fan from an eBay seller when you can get it for about the same price directly from the manufacturer? Here's a link to their fan page:

http://www.muzzys.com/fans.cfm

The actual price of the fan is cheaper than the eBay seller, but the shipping is slightly higher (at least to me in FL). I would think it'd be easier to trust a company that markets a product, rather than an eBay seller, but that might be just me.

I have muzzy's fan blade. I cant compare it to the stock fan cause mine was broken when I got it. So far with it on I havent seen the temp gauge go to far past middle. Dont think it has even gotten close to overheating. Ive had it out in 85 degree temps. Boy does it kick some heat out tho. For 40 bucks I think its a well invested replacement if you are doing any work on the radiator. The original fan is 2 pieces plastic blade and a metal plate held together by glue, the Muzzy version is 1 solid piece of aluminum. I am very happy with the blade. BTW I do HVAC so I am working with fan blades all the time only alot bigger. Good quality.

Ok, got the Muzzy fan blade and it had 6 blades as advertised. But when I took off my stock fan - I found that the fan has 7 blades!

Did Kawie change the design at some point? So, which flows more air - the muzzy with 6 blades or the stock with 7?
