cooling fan ?

[juliman]

hey guys , i was thinkin about something today...not good , lol.......and i had this idea, if you were riding along and your motor started to over heat, you would have to sttop and let it cool down for a while, if it over heats then it will decrease engine life and your probably gunna be late for work lol, so i thought why not mount a windscreen washer pump out of a car ( about 2/3-1/2 the size of my fist) on to the frame with a fan blade on it pointed at the motor, you could hook it up to the light cable( cable used for light s lol duh)
and if u stopped at a light it woulkd keep your motor cool, you wouldnt even need a switch or a battery, the electric motors are cheap and last long and if it ran while you were riding down the street it wouldnt have much effect but it all still helps, ok ill try to explain my theory.

fan on frame,hooked up to wires used for lights from magneto
fan points into cooling fins
blows heat/ air through when idleing/ not moving but motor is running
helps add more air when moving? should help engine life? plz add thoughts and try it ( i havent got a motor on my bike yet still savin lol, got 200$ )

lol nother quick idea, wat if the fan was in a shroud so the little blade doesnt cut your leg ....lol

soz for posting twice but i thought i put it in a bad spot first time lol

Won't work, the small motor will draw too many amps and those motors are 12V where as the out put of the white wire is somewhere 7.5V....turn on the fan and it will kill the engine.

It gets well over 100 degrees and I have driven 25 miles at a time and never had a problem....Fans are not needed for the engines....

lol yer ok just an idea

[craisin]

computer fans run on 5.5 volts you maybe able to get a voltage regulator cheap as.

first of all, why would your motor overheat? It's air cooled is it not? if you are riding / moving, the air rushing past the cooling fins on the head will cool the motor.
and you say, you'd have to stop to let it cool down....actually a non running hot motor will only get hotter as it sits not running because there is no air flow going past the cooling fins to dissipate the heat.
motorcycle motors. lawnmower motors, weedeaters, go karts, minibikes, etc. , 2 strokes and 4 strokes have been built like this for a reason and they have been this way for many years....I have NEVER seen one overheat except when one is running too lean....and in that case, the motor usually just locks up.
unless your motor is totally surrounded by a fairing where no air can flow past the head, or if it is liquid cooled..there woudl be no need for a cooling fan.

its not as if I favour having a cooling fan.
Better 2 stroke oil is a better way around the problem.
If your using plain motor oil that will be the problem.

Some people seem to think you can use more low-quality oil per litre of gas, but your lowering the octane rating.

Im not saying you are doing these things

[DougC]

I don't have a HT engine and am not real familiar with 2-strokes..... how would you know that your engine was overheating, other than it stalling out (the carb vapor-locking)?

ok thanks guys i gues this was just a silly idea my imagination came up with, lol but thanks this might help other ppl with the same idea lol, and now i really think about it you guys are right

Howdy Juliman. Some of the best ideas are "silly" Keep right on letting your mind wonder and sharing. I have a buddy in AZ who does, well did (he switched to 4 smokers) have a problem with over heating. We got to BS'in about it and I designed a cooling system for him based on a drip coffee maker. Have you ever soldered a pipe? all the heat draws water to the heat source. A modern coffee maker does the same thing. (no pump)

So, if you put a small radiator on the down tube behind the front wheel and wrap the head in copper tubing. Connect it to the in and outfall of the radiator, in theory, should circulate hot and cooled water. (LOL, I know "in theory")

I live in CT so hot is not a big problem but want to make one of these some day just to see. On the 2 smokers, I do see a power loss when they get hot.

Keep posting! If we were sane, we all would never have met. lol
