heat sink cooling fins for extra cooling power!

So I Have another idea to attach cooling fins like the ones they use in computers to help keep cylinder temps down Or maybe even the clutch!

I feel like this has been done before? (edited)

Re: heat sink cooling fins for extra cooling power!

Been done before with heat sinks 3 times that size. There are threadz with pics around.

Re: heat sink cooling fins for extra cooling power!

So it does work?

Re: heat sink cooling fins for extra cooling power!

I came up with :

To take the place of broken fins on my Simplex head .

But , ended up doing this instead :

The 'new' 'fins' are held in place by the spark plug . I used a bit longer plug reach to accommodate .

And , yes , they do help it run cooler .

I came up with this after a quick search:

Thanks Stephen. I remember seeing several styles and pics here on MA.

No I didn't make them I bought them from the guy who did. I think his name was Max dratchen or something like that? He made a reed block adapter for the av7 also.

Re: heat sink cooling fins for extra cooling power!

Max Johnson made these, he’s from Southern Mass near Rhode Island. They were called Gorgon heads. Dude built a variated bike with a55 cases with one of em. Wild dude, bought a Hero Puch Turbo Sport he had built and it had express reeds on it

Re: heat sink cooling fins for extra cooling power!

Wtf Another guy from Massachusetts?

So I found his account! https://www.mopedarmy.com/riders/motodrachen/

His last post was two years ago. I Might try harassing him into talking. I wonder what he’s up to now adays. (edited)

Anyone ever experimented with some form of ram collector to channel air to the head while in motion? It was a pretty big thing in motocross at the interim between air and water cooling. Usually it was a shroud/cowl attached under, or integrated into, the tank kind if like a fairing. On an e50, I've imagined a small metal cowl with four mounting points that could be mounted under the head nuts. It would mainly channel air into the fins while in motion, but also provide some heatsink at rest. I'd meant to draw something in cad to post here, but since this topic came up....

It would be really really simple to fan up and experiment with

A fan on the flywheel with a cover & ducting aiming at the cylinder would be tight

Uh, v1

Cool, thread over

Someone besides me has validated the superiority of the V1

Re: heat sink cooling fins for extra cooling power!

Our AC MBK race bike has a big aluminum collector under the tank to direct more air across the cylinder and head. Super simple design.

Awwwww, don't ruin all the fun! Idk though, I kinda like the Garelli team better. Just saying......

Re: heat sink cooling fins for extra cooling power!

air cooling is a cool topic. i went with the water cooled gila head after tinkering with the idea of ram air, copper coils, cooling fan..

the questions that i still have is what kind of oil or oil/gas ratio is optimum at X temperature. I'm wondering if my liquid cooled head thats running at 280f @ max head temp is too low of an operating temperature.

Re: heat sink cooling fins for extra cooling power!

Minarelli, vespa, some puchs, APN's and a number of other bikes have the wonderfull "forced air" cooling.

Conventional or synthetic would be a variable too.

Re: heat sink cooling fins for extra cooling power!

come on guy lc is where its at. you can do just the head and it will work.

The garelli clutch just kills me tho

Re: heat sink cooling fins for extra cooling power!

The late-model Gary's had puch style surflex's with CDI's and were awesome.

I will definitely never own another rubber clutch garelli, nor will I own a V1 tho.

Why is that?

Re: heat sink cooling fins for extra cooling power!

Rocco, people do bolt those find to the side of the head to help with cooling.

No it’s not! It could be fine, you Gotta know what the exhaust gas temperature is,
