Banshee's have some the wierdest stock exhaust systems.Never understood the expansion chambers.

 

Today I noticed that rockymountainatv.com had a sale going on with free 2 day shipping and if u spend over $500 it's 100 off, so I decided to tell my dealer about this and he is a direct link to Toomey so he's going to match or better the price of $550ish for the t6 kit which includes: airbox outerwearer, air filter, pipes, silencers, and proper jets. I think those upgrades will crap on a 450 in a straightaway. Do you think this can compete with a piped/jetted (or programmed) 450?

Btw I appreciate the feedback. I've heard stock banshee's run 72 mph which I think is about right.

 

ive always been told 68-70, but everyone has a different opinion, as long as someone dont jump on here and claim their stock banshee could run 90mph, well be okay...

 

I think you will have those 450's going to the shop for some cam upgrades

 

cam upgrades. lol...the major thing I love about the 2 smokes is the simplicity.

 

You're on the right track with the pipe and silencer upgrade, but before you start jumping on slightly modified YFZ's (slip on muffler, airbox lid removed and K&N filter) you might want to look into a few more mods like maybe some higher compression heads, some port work, bigger carbs and reedcages.I like Banshee's, but the new 450 sport bikes are pretty mean from the factory.The Banshee has much more potential for dragracing, if you're willing to put the money into the motor and chasis.

Here's an old article from DirtWheels magazine.These numbers are with some work done to the factory heads.Over $900 in mods







Same issue of DirtWheels a YFZ450 slip on pipe shootout.YFZ had airbox lid removed and K&N filter with rejetted carb.



This is the pipe that I have...Pictures in my profile page...I don't use a spark arrester like the pipe in the test though

 

Stock for stock, banshee and YFZ are pretty close, but the YFZ gets off the line better with its better stock tires. Even faster is a raptor 660 stock for stock for stock. Piped and jetted YFZ vs. piped and jetted Banshee, the banshee has the upper leg but it is still close. However after I ported out my banshee myself, the YFZ couldent hang.

 

Yfz 450's have a little more top end then the raptor 700r. A stock 350 banshee will do about 73 mph stock. Pipes and jetting on the banshee will amazingly wake the thing up. It totally makes it a whole diffrent bike. 450s and raptors are better for race tracks though man. Rider skills has alot to do with everything that happends.

If you set up a shee right and you have the budjet, You will burn any 4-stroke in a strait line.


My banshee courrently has the following mods:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Pro circuit pipes and silencers.
TPS Dune portjob.
cool head.
20c domes.
+4 timing kit.
38mm Keihin Carb.
+4 swingarm.
+2 axle
+3 front wheel spacers.
Itp holeshots.

I still get beat by plenty other banshees and some 450rs.

 

what gear ratio are you running on your shee?

 

I am running 15/40 gearing with my rear tires are 20 inch knobbies.
