I don't know a lot about reeds and was just wondering if all snowmobiles have reeds. Is it a carb vs. EFI thing? Thanks in advance and sorry for my ignorance.

No not all sleds have them. 4 strokes do not use them because they have valves. 2 strokes do use them but not all of them. A 2 stroke was designed to be light and compact therefor no camshaft or valves. Normally a 2 stroke has either reeds or rotary valve. Both have there grins and groans. The trend now is towards reeds and it doesn't matter if it has efi or is carbed.

:withstupid:

It all depends on how the manufacturer designed the intake system.

There is a good tech article on reeds right here at the SW.com Technical Area:

:D

http://www.boyesen.com/products/motorcycle...ycle/index.html (http://www.boyesen.com/products/motorcycle/editorials/cycle/index.html) nice article by the master k. cameron.I remember when most sleds had no valves,piston port motors.

I am going to kidnapp Kevin Cameron and force him to live in my garage and tinker with my engines.

He will be fed on a per horsepower gained system.

I believe this is resonable, and I will gladly allow others access to my new found knowledge for a SMALL(large) fee.

please email or PM with specifications and horsepower requirements of your project.

I am hoping to have a 2 stroke weed wacker that makes 1 hp per cc next summer.


I sure hope the FBI isn't reading this

Thanks for the info. I guess I'm kinda dumb on the subject because my last sled was a '95 Wildcat, which as I understand didn't have reeds, since it was a piston port motor. Now I have a ZL 800 EFI SS, so I want to learn more about them.

All wildcat engines are a combination of piston port / reed design.

The old 440, 500, 530, 650, 700 were of the same design.

The new reed engines are far better in my opinion. :)
