im gonna soon see what happens if i wire a pc tower fan or small automotive fan to my sprees cooling shroud hehehe

If you're gunna do that, you should use a pc tornado fan. My buddy had one and it was silly how much air it moved. I'd only do that for idle, because at speed, a scouped air duct would probably pull way way way more cfm than a fan.

Am I right guys?

Nothing good.

Its proabably not gonna do anything works like old VW's you need to figure out a way to get compressed air blowing through your carb you'd probably have better luck duck taping a garden hose to where your air filter should be and when you need a boost take a couple of good breaths and blow in that thing as hard as you can. I'd run pre mix for that though

Re-read the topic.

that can work, use pvc and angle it twards the vent, also use header wrap tape on the j- pipe

For best results you should attach a small thremostat to the head and turn the fan on only when it comes up to temp. Too much cooling air and it will never get warm enough to run properly.

Is this really necessary though? I mean there's a bunch of kited scoots on this forum and are they having cooling problems at idle? I'm pretty sure they're only having problems when they're at WOT and have jetted the carb to be closer to lean to get max power and end up toasting their cylinder that way.

And at 60mph, a good air scoop is gunna gather more air than a little computer fan.

Now if you run a radiator setup, then yeah, get a fan on that radiator.

Greetings:

Idle speeds produce low cooling airflow, to be sure. However this is easily offset by very limited heat production. Even without a fan, the oil temperature on my Sportster drops considerably when it sits in neutral or riding "parade duty" at 5-7 MPH. The hottest it gets is during sustained high speed operation, despite the 100-MPH wind blast blowing over the fins. The same applies for virtually any air-cooled engine.

It's just not necessary to augment cooling airflow. I won't even get into the issues associated with providing AC current at the right voltage and frequency to run an electric fan with your scooter's tiny charging system. No telling how many components you'd blow finding out how. Lots of expense and work to answer the "Can it be done?" question. A better one would be "WHy would you even try?".

Well, it might look cool. I've seen some computer fans with sweet colored lights......another "coolio" idea is put a wistle on it to make it sound turboed...

Yeah, computer fans operate on 12 volts, so no AC would be needed, but........just get some strobe valve stem caps.

i think that light up valve caps are tacky but they could save lifes riding in the dark

I had once thought of something like this when I got my first scooter - a 1987 Yamaha Razz. However, with the bike on the stand, and engine at full speed, it had so much suction that I could have hooked a Shop-Vac hose to it and cleaned the house. LOL

So at best what you'll get for a result (and I did this because it sounded neat on my 85 Spree) is stick the fan on there unhooked for a unique trubo type of sound. Wide open, it makes a killer whining sound. My first guess though, is that with the fan spinning at 10K, the bearings in it won't last long, but the sound is cool and one of a kind, nonetheless.

you can get a fan at walmart
