Waterpumper cooling tricks for R's

[crackshot]

Anybody got any?
R's seem to run hot on 90 degree days!

A cold beer always cools me down on these hot summer days! :Bounce :rolleyes: :postwhore

Dry ice in the air box will cool it down LOL. :lol:

pwr makes aftermaket radiators, you can get 20 fin super coolers, my atc tends to run about 190 with the 310pv, engine ice, 20 fin cooler, short track kit(bigger radiator fins) and stock radiators. I have a temperature guage on it. My bike is getting a partail rebuild, black plastics, black short track tank and shrouds and I am gonna put on the pwr radiators. The pwr's cost me about $400 and look alot better and appear to be double pass instead of single pass like the stock ones are. I'm hoping the temperature drops some with the pwr radiators.

A temp gauge is a must in hot weather! Engine ice is also good.It was 112 sunday and we were riding,but I just watch the temp,and never let it get hot!! Also race gas will help you out.

[deathman53]

my bike requires race gas, 230 psi, it far too much for pump gas.

That engine ice really work? Whats the max temp on an R before you should shut it down? 210 degrees?

[ChrisD]

Didn't Bryan Raffa already post this for us? "Water Wetter" or something like that? I'm going to try it in my bike this summer.

[deathman53]

the max temperature is about 230, over that you should shut it down

[Howard]

Water wetter is made by red line and they have some good products as well.

Don't leave water wetter in your bike over the winter or it will freeze!

[Howard]

do those inline finned coolers actually do anything?

[Kintore]

Something about engine ice raffa posted, Lowers temp by like 30 degrees I think. Do a search for it.

[deathman53]

it seams like they work, the 5 fin pro-design ones don't do anything, 20 fin coolers tend to work alittle better.

I thought this up, but in New England there's really no need for it..... See what you think.

Take 2 of those little 4in wide fans that are in the back of computers (I believe they come in bigger sizes) and mount one in front of each side of the radiator. As for the power source I would imagine a 9V battery on each one would be sufficiant??? When you are going slow or the engine is just sitting you could have a little switch and throw them on. It would be pretty effortless to wire..... Plus those little fans can move a lot of air!

*EDIT: I fogot to mention that ESR heads also run cooler than stocks! Check it out on there website http://www.esr250.com/250r_various.htm#honda *

On a "stock" motor, I would never worry about it, but on my ESR....danm that thing runs hot. Anything to get it to run cooler. I don't worry about it blowing up, but when you are pushing for every ounce of power in a race, it would be great to get it to run at a lower temp.

ktm makes a fan that bolts to radiator, when I get that I will first test fit it on my atc250r and see how it fits. the kit with the fan, themistat and wiring cost me $81. I ordered the fan for the ktm bike I bought yesterday

Engine ice works well, race gas seems to help on my bike, and esr makes a dome which provides quite a bit better cooling and looks cool too. The dome they say gives 20% better cooling than a stock set up. www.esr250.com

I use engine ice and i notice my bike cools down much faster after i shut it off... While im riding i like to wear shorts alot and i don't notice the heat from my pipe as i use too before using ice.....ALso try a br9 plug.. Those vids i posted a week ago, it was around 105 and my bike ran pretty dam well as you can see :)
