I your considering adding an additional radiator you can check out my thread under 250's. I'm converting a tank 150 to a 250 so I have to build a complete cooling system. I used a honda helix radiator and mounted it to the frame behind the front wheel.

Madcollie...You got it man! This is kind of my take on what it would look like it a Whizzer met a cute little chinese scooter and they had a child.

My wife's opinion......" Congratulations, you made a $1000.00 scooter look like. $200.00 mini bike".

Got the front fender mounted. This is how it looks.

First a little history. Ethanol has been used as a motor fuel for almost as long as the internal combustion engine has been around. Henry Ford"s first cars were designed to run on ethanol. He was never a fan of gasoline but had to give in as the oil companies gained more and more power.

I agree that an E85 car will lose fuel mileage when using the E85 instead of gasoline. The reason is that your running 85% ethanol in an engine designed for gasoline. To successfully burn ethanol you have to designed the motor for it. An ethanol based engine has bigger injectors or jets and much higher compression (as high as 14 to 1).

Now lets talk about efficiency. A gallon of gasoline contains more joules of energy then a gallon or ethanol. As stated before you have to run a richer air to fuel ratio with ethanol. This would all lead people to believe that your could never get as good of fuel mileage with ethanol.
There is another factor present in this equation, Thermal efficiency. Gasoline burns at a very fast rate producing a quick explosion and allot of heat. Ethanol burns much slower and with less heat The piston receive more of a "push" then the quick shove of gasoline. With gasoline a high percentage of the energy produced is lost to the heat of the exhaust and the cooling system. With ethanol much more of the energy is turned into useful "work" and less into wasted heat.

As far as a stock scooter goes, you are correct. Using a high octane fuel when not needed is a waste of money and can actually lower fuel mileage regardless of weather it has ethanol in it or not. My wife's scooter cane with a sticker form the factory requiring 91 octane. It seamed to run just fine on 89 octane. That was before she decided she needed to keep up with her girlfriends Zooma. It now has a 77cc big bore cylinder. The head that came with the BBK did not look very good so I ported and polished the original head which has a smaller combustion chamber then a BBK head dose. Thus raising the compression ratio. The end result was a very fast little scooter. She can easely run away from her friends stock Zumma. The down side is that with anything less then 93 octane it doesn't run very well and could damage the engine.

My apologies to Blindrider for hijacking your thread. I will shut my big mouth now.

You get to ride in country some of us can only dream of! I'm stuck in South Dakota where the high today was 16 degrees. Oh well, as long as I have a snow blower, a 4 wheel drive, and a heated garage I can get by. It dos give me ample time to get projects done.

Today made the mount for the frond fender. Just have to clean up the welds. Wish I was a better welder so I could just run a bead and be done. instead I have to weld and grind, weld and grind, weld and grind, you get the ida. This part is going to be very visible so it has to look good. Hopefully tomorrow I can get the front fender mounted. I don't have much hope as the wife has the day off and that usually means I don't get much done in the garage!

What is the displacement on that Jetmax? If its a 500cc I could definitely see one of those in my future.

Anouther view. Don't judge to harshly yet!
