What does it take to make a 4 strokes Banshee, act exactly like a 2 strokes Banshee?



I want the graph to be exactly the same for both(torque and hp).

 

There are no 4 stroke banshees. I'm not sure what you are asking.

 

Never seen a 4 stroke banshee here either, unless it was a street bike engine swap.

And to my knowledge there are no plans for a 4 stroke banshee in the future, at least at this point in time.

 

common guys, I know there is no 4 strokes banshee.


I mean what it takes to make a 4 strokes quad act exactly like a 2 strokes banshee?

I mean is it possible to make a 4 strokes quad act exactly like a 2 strokes banshee?

 

The horsepower and torque curve on a four stroke will be different than a two stroke. The closest thing to a banshee that I've ridden is the YFZ 450. It has a similar hit to the banshee. It does have a wider useable rpm range and stock for stock it is just as tough or tougher than a bansee. If you have not had a chance to pilot one, I highly recommend it[img]i/expressions/face-icon-small-happy.gif[/img]

 

Maybe a really aggressive cam?

 

you cant. I guess the 450 is the closest but the hit it has is still nothing like a banshee hit.

 

I agree, the YFZ450 feels like it has a power band like a banshee.

 

Basically a very aggressive set of top end cams (or cam) and moderate compression will give you that powerband "hit" you are looking for. But only a drag racer is going to be able to make good use of it.

The "hit" of the banshee and the narrow powerband is one of the inherent problems with the bike, not an advantage. The aftermarket sells millions of dollars in products every year designed to broaden the torque and hp curves of the banshee. But hey, if thats what you want you can make a 4 stroke considerably less rideable too then go for it.

 

Banshees are fast even when stock but the way the power comes on makes it seem faster than it is. For example, a stock Raptor just does not feel like it will keep up with a stock banshee (IMO). This is due to the smooth power delivery on the Raptor and the wild power delivery on the Banshee. The truth is that these machines are a close match stock. For all around riding, you are better off with a bike that gives smooth power delivery from idle to redline.

To me a two stroke feels like a small four stroke with a huge nitrous shot available every time you gas it.
(This is not necessarily bad, this is just what it reminds me of)
