But in the dunes, you have the RPM advantage over the 450

Not much RPM advantage and unfortunately not as much advantage as the low end advantage the YFZ has and the Banshee weighs 35 more lbs. A stock Banshee won't take a stock YFZ, however they're not that far off.

I guess the truth just hurts a little.
I think I'll go hug my banshee and tell her it will be ok!

Apples and oranges. A yfz engine from the dealer is almost at its hp limit. An aftermarket exhaust, filter, and some fine tuning on the jetting may get you another 2-4 hp. A banshee engine from the dealer is in a severe state of restriction. A set of pipes, air filters, and some jetting will net you about 12-15 hp. Advantage banshee. Try to get those kind of gains from any of the new 4 strokes and you will be out some serious coin. Not to mention the life expectency of your top end is about the same as a scheduled piston change on a 125 2stroke.

You must have some very bad information. A stock YFZ engine is now where near its HP limits. Stock the YFZ engine is very de-tuned. Get a intake, exhaust, do the cam mod and your talking 10+ more HP. May be I should let you take me YFZ for a ride to see that I'm getting way more then 2-4 HP more then stock . Not to mention I've wasted many mildly moded Banshees .. mild being pipes, airfilter, and jetting.

I'm talking bolt-on. No internal engine work.

I guess if you believe everything the mags tell you then yes, my info would be very bad. Unfortunately, for you and the mags, I've helped out on and off at local performance shop for the past 7-8 years. The dyno dont lie.

I don't doubt that you've wasted some banshees on your quad. The yammy 450 is probly the best sport quad ever made. But as far as hp goes, the banshee engine is far superior when it comes to potential hp numbers.

That was my attepmt at sarcasm. I can't log on to a dirtbike/atv website lately without reading about all the top end problems with the new 4strokes. My point being 4strokes are no longer the "gas and go" machines they used to be.

No they aren't your daddy's 4 stroke...that's for sure. lol. But in my experiance they outlast the pingers 3 to 1 on rebuilds...however when you do rebuild the 4strokes it can get expensive, so it evens out really.

All I have on my YFZ is bolt-ons and I can guarentee you that I'm getting more then 4 HP over stock. Like you said .. the dyno don't lie...checkout what mixxer has been doing over on trx450r.org with his YFZ with bolt-ons.

One thing I don't want to do is turn this into a bash session. If there is one thing I like the most about allthingsmoto is that there isn't any bashing between members like most of the other sites out there. I just don't think your information is reality. BTW what type of quad do you ride?

I agree that the Banshee is tough to beat if you have deep pockets, especially for hill shooting and it definitely has it's place in the ATV world. However your information is a bit flawed when talking about gains. There is a man on this site (FFRacing11x) that has a YZ450F that puts out 60 plus hp and is still reliable and the YFZ has similar potential. I know there are Banshee's out there that put out more than that though, so I think I get your point, but dollar for dollar, I think the YFZ holds it's own quite well, as I too have beat many Banshee's in hill climbs with just my pipe, K&N and jetting.
