lighten flywheel in trails?

[endofitall9]

been doing some reading on getting my flywheel lightened, but before I do, I wanted to know if it would be a good idea for trails/hairscrambles, and also if it makes it easier to stay in your band?

Its a great idea

[endofitall9]

who does everyone recommend doing it and how much should it run me shipped?

You sure abot that My experience has been that when setting up a 2 stroke for trail riding you want to put a heavier flywheel on it. An example is for 2 stroke motocross bikes that get converted for woods riding a very common add on part is a heavier flywheel. Just my 2 cents...

a banshee is different than other 2 strokes when it comes to lightening flywheels. banshees dont have low end so by taking off weight you get an increased throttle response which allows to create more power in low rpms. by the banshee having a heavy flywheel it doesnt allow the motor to rev faster like with a lightened flywheel in the low rpms, so u dont get that instant power, instead it gets there in the later rpms.

decon hit the nail on the head thats what i was wanting to know, I think I'll be getting ahold of boonman

Thats true,but what it does is give the engine a more linear powerband.Sometimes when traction is limited or the terrain is very aggressive,a heavier flywheel will make the engine less pipey.

 

I've only seen this on open class 2 strokes,like 500 hundys and such.The one thing I noticed on uphills was I use to be able to feather the throttle towards the top of the hills.Now I have to make sure I carry the powerband until I crest it.

 

Other than that,its a great mod.Less rotating mass=less hp lost

Well that was kind of my point. For trail riding you want a more linear powerband, which is why I would hesitate doing that mod if you are a woods rider. I ride my Banshee exclusively in the sand so it is a good mod for my purposes

I can't speak form theory, only real world experience. It takes alot to get a Banshee's powerband linear. I tend to ride wide open then brake. Maybe the lightened flywheel just happens to suit my riding style. To me it lets the Quad rev out of it's dead zone, which on a Banshee is quite large. Just my thought, take them for what their worth.

You have to also remember a Banshee has a power stroke every 180 degrees of crank revolution as opposed to a single. The flywheel only truly serves the purpose of timing and electrical on a banshee. I ride trails and I wouldn't be without a lightened flywheel, much much much more fun to ride.

You make a very good point and maybe with the twin the flywheel effect is not nearly as pronounced. This is my first twin and I am applying my experience with a long line of 2 stroke singles. Still, am I correct in assuming the the lightening of the shee's flywheel will cause it to to rev quicker If so then at least when we are talking about tight technical trail riding that is not what the doctor ordered.

woods and trails require power off idle and bottom end. a lighter flywheel makes your powerband available to you rightoff idle and gives it instant grunt off the bottom rpm exactly what you want ,only down fall :rpm falls as fast as it climbs ,so you need to keep on the gas alittle more into corners and such

I disagree,anytime you add or remove weight from the fly wheel your altering the rotating mass.This will directly affect the engines powerband by way of a softer hit or harder hit.

 

The more mass,the longer it will take to reach powerband. Also providing tractable power on loose surfaces

The less mass, shorter rev up time needed to reach powerband.Ideal for high traction conditions.

 

The banshee crank is no different than a conventional counterweight/counterbalance single.There just balanced different ways.A banshee uses another crank journal offset 180 degrees.A single uses a counterweight/counterbalance to balance itself.
