fitted a computer fan on top of cowling aimed streight at the barral ive wired it up one to earth other to a live feed, do i need a inline fuse the fan is 13amp it seems to work well any input appreciated.

i had the exact same thing in mind!
spied one at work and it got me thinkin

interesting ,but firstly why do you think your PX needs extra cooling ?
secondly ,there are great benefits to fitting a scoop on the panels and by removing the lower fins on the flywheel cowel hence letting in more cool air to start with .
your computer fan maybe could work ,but i have my doubts tbh ...
have you done any tests to prove that it provides better cooling ?
at best i would imagine that it blasts down over only the barrel fins and so may actually hinder cool air travelling over and around the cylinder head ,and without a hole in say the top of your side panels its only ever going to try to cool with hot air to start with .
plz let us know how this works out for you

Hey up matey think you've summat wrong cant see that fan fan being 13 amp as that would be 13 x 12 = 156 watts. That would be more than your stator can give out

Agree with Sean, whats up with Vespa cooling ?

Stick your fan on a Lambo' and it might be a good idea but i think it's been done.

Nice try though

Really. You are at it.

was just playing around with the idea, was having the pannals modified to help drag cool air in, need to do a test without say 10 mile down bypass then check cylinder with my digi thermometer mark the barral so test same area, then switch fan on and blast back home repeat check? it does say 13 amp on top of fan?

I am sure that fan doent draw 1300 watts. More like 1.3 amps surely.

just read it with my glasses on and its 0.13 amp so do i need a inline fuse?

Yes. If the fan or wiring went tits up you'd fry your stator.

Surely any air that is meant to go round the barrel will now come in the bottom and straight out the top
