Reeds

[Gargamel]

Ok for my understanding the reeds are where the carbs meet the engine. So there is a orangeish gold piece about 3\16" thick beteen carb boot and engine.

 

Question - is this the reed cage or a reed spacer. Trying to identify mods on my new shee.(Got my shee CHEEP from dealer same day it was traded in and he was a dumb a$$ too). Clymer is on back order

thanx for all the help.

That would be the stock reed cage.

 

I like the nick name too...

yea stock reed cages, dont put in any reed spacers, dont do shit

The Clymer was a great idea.It will help you out a lot.

haha your guys are gonna crack up but when the hell is a clymer? and on the topic of reeds what is better: deta v-force, boyesen power reeds, and theres some other power curve reeds

Clymer is the guy going up the hill. Just kidding, its a brand of shop manual.

 

Reeds act like a one way valve that keeps the air and fuel moving forward into the cylender and stops it from flowing backwards. When the piston is moving down and the intake port is open (so it is sucking fuel in) the reed flexes to open the passage, when the piston is moving back up it wants to push the air back towards the carbs but the reed is pushed against the reed cage closing the intake tract and blocks the air from going back. The reeds mainly affect your power delivery characteristics and typically dont make a whole lot more power overall, but may add more power in certain RPM ranges and tune the intake for the type of power you are looking for. So the best ones are the ones that fit the power delivery that you are looking for. Typically the basic reed is either more flexible and opens easier for bottom end or stiffer and harder to open for top end compared to stock. A stiffer reed works like a stiffer spring on a 4 stroke valve, so when your at really high RPMs you dont "float the valve" so it in effect it doesn't just stay open. A lot of reeds are desinged to try to give the best of both types of reed in a single reed so you get better bottom end throttle response and power with better top end power too.

 

Delta V-force is an aftermarket reed cage where you have a double wedge design so you get 4 reeds (2 wedges) to each cylinder rather than 2 on the stock single wedge shaped reed cage. This is probably the best since it may offer more overall flow and add power rather than just change it. Boysen power reeds have 2 holes in the main reed with 2 smaller reeds on top of the main reed covering the wholes. So the small ones open first (I think) and are more sensitive and open easily for good bottom end and throttle response and the larger petal is stiffer so it opens on the top end and gives better power at WOT. Power curve reeds have a tapered thickness (I thinK) so they theoretically are sensitive at the tips and open easy on the bottom end yet most of the reed is thick so it behaves like a stiff reed on the top end for better top end power. Pick your reeds based of what you want them to do. Ported reed cage with stiff reeds for top end. Or power reeds for more bottom and mid. V-force is probably best all around but costs +$200. There's a lot to choose from and I haven't got it all completely figured out yet, if I've goofed on any of this info please feel free to correct me.

I have ridin a banshee with v force twos and one with boysens and they had the same mods. I liked the v force equipped banshee much better and have heard they are a better all around reed. I plan on getting the v force later this month along with a 409/ported cylinders.
