MOPED ARMY

I bet somebody stuck it on a lathe and machined the fins down some for reduced drag.

they sold them on a site in europe i was looking at im guessing they are lighter but the fins are untouched

inside could be different

good eye Ed

it aint going to be any different

it should have curved blades then it will have less drag and spin faster

bullshit

Damn placebo parts. I tried modding a V1 fan for less drag, it didn't help/hinder the motor. Heck the best thing you can do for a slow V1 is port the sucker!

75cc Polini works sweet too.

Wouldn't a performance fan increase, not decrease, airflow for better cooling, increasing performance? I don't think the spinning fan is holding you back.

somebody could do a resin cast also using silicone as the mold to make a lighter fan.

Jon that is HOT!

Im going to ask cause Im not sure but, is the fan really needed other than at very low rpm and at a stop?

The reason I ask is, isnt the cooling fins being exposed to enough air at speed that the fan isnt needed.

On a automobile the fans do nothing to help keep a radiators temperature down over 35mph, the air that is passing through the fins is more than sufficent, thats why they make fan clutches for car/trucks.

I know there is a lot of two-stroke engines that dont have any fans at all, has anyone ever tried to run without the fan(not at an Idle/standstill) for a period of time to see what happens.

Plus, then you'd probably have to remove the fan/flywheel cover to let air flow over the cylinder fins. That would leave the flywheel exposed to dirt, water, etc. Plus it would look ugly. I suppose you could modify the cover, but then your cover is ruined if you ever want to put the fan back on.
