radiator cooling mod - mixing question...

[Doug Pippin]

Mike I've been meaning to try stuffing foam in the gap to see if there's any cooling benefit, just haven't had time yet. The biggest improvement I've seen in cooling is to get the carburetor jetted correctly. My KLR came with stock jetting set too lean. A lean engine will run hotter. When I re-jetted the carb it improved the engine performance and the engine ran cooler. It used to run near the middle of the heat gage now it usually runs from 1/4 to 1/3 from cold. It will heat up when in slow moving traffic and sometimes the fan will even come on. It will run a little hotter when the ambient temperature is hot and it runs cooler when the ambient temperature is cooler. I'll still try the foam to redirect the air flow through the radiator and see if it makes any difference. Doug in NC At 08:53 PM 7/22/04, you wrote:

Cooling? I live in Vegas. My temp gauge rides in the center of the gauge when moving, and barely rises to 2/3 when stuck in traffic. Oh, riding through the Mohave desert 2 weeks ago in air that was over 110 degrees at speeds near 90mph with a full load of gear and my bigass 240 lbs., it never exceeded 60%. One sentence - Correct AF fluid and distilled water, and Redline water wetter.

Reverse answer - First - you do not know about my KLR 16 - the facts are in archive - It is well modified. 2nd Q- Can you not find my prior 100's of posts? Antifreeze Q - Do you not know about Redline products? I am not being a smartass. I just don't get it. So much time, and so little free... Try this first - it may help you get a handle on my little KLR A16- http://vegasklr.smugmug.com/ Mike Torst Las Vegas -----Original Message----- From: don dotson [mailto:harmonicamoon@...] Sent: Thursday, July 22, 2004 8:01 PM To: mike torst Subject: RE: [DSN_klr650] Re: Radiator Cooling Mod. --- mike torst wrote:

What is "correct AF fluid"? So you have never rejetted? thanks, Mike, don in UTah =====

Mike, I think that the "tone" of your reply to his questions was unnecessary. This list is all about helping each other, about supporting the KLR community in general and I just don't think that there is any room for attitudes. You seem to be on the ball, so why not use your knowledge and experience in a more friendly manner? Even considering the subject line and matter, *I* wondered what in the world "AF fluid" was, and only now ASSUME that you meant "Antifreeze fluid" although I've never actually seen or heard it with the word "fluid" appended. Also, there is no watter wetter sold on the shelves around here and I wouldn't have known what it is if I hadn't seen it mentioned on the list. When he asked about rejetting, couldn't you have just said yes or no? Why should he have to have an intimate knowledge of what you've done to your bike? Peace, brother.

Mark Water Wetter is a product sold by Redline. It's mainly used for race cars and race bikes that are not allowed to use antifreeze in the cooling systems because antifreeze leaves a slippery surface on the track if the fluid leaks out during a crash. When Water Wetter is added to pure water it prevents the cooling system from corroding. It also has the benefit of making the cooling system a little more efficient. Your engine will run cooler with water than with an antifreeze mix. It will run cooler yet with water and Water Wetter. WaterWetter is a unique wetting agent for cooling systems which reduces coolant temperatures by as much as 30 F. This liquid product can be used to provide rust and corrosion protection in plain water for racing engines, which provides much better heat transfer properties than glycol-based antifreeze. Or it can be added to new or used antifreeze to improve the heat transfer of ethylene and propylene glycol systems. Designed for modern aluminum, cast iron, copper, brass and bronze systems. Compatible with all antifreezes, including the latest long-life variations. I use Water Wetter in the cooling systems of all our motorcycles as well as our automobiles. You should be able to find Water Wetter at any good motorcycle shop, especially if they support road racing, as well as some Auto Parts stores, again those that support racing. For info on Water Wetter see: http://www.redlineoil.com/products_coolant.asp?productID=53 BTW With Water Wetter and a rejetted carb my KLR runs much cooler than it did in stock condition.

Hmm... I am in California where I don't need the antifreeze component of coolant. Sounds like I would be better off with Water Wetter since it gives better cooling. True? Any downsides other then cost, I assume it is a more expensive? -- Doug Herr doug@...

Mark I think Fred Hink answered your question on Water Wetter but I'll chime in also. A bottle of Water Wetter is 12 fluid ounces and will treat a automotive cooling system of 12 to 20 quarts. I paid $8.48 for a bottle here in Asheville NC. For other uses (such as motorcycles) you use 1 ounce of Water Wetter per quart of coolant in your system. So you don't use Water Wetter to replace the distilled water just to supplement it. I live in the North Carolina mountains and we do have freezing temperatures here so I just add the Water Wetter to the coolant. If you don't need protection for extremely cold temperatures you can reduce the antifreeze content in your cooling system (less antifreeze/more water) and it will increase the temperature reduction.
