How long will a banshee engine last




















The lower end of the price range is going to apply if you have a 2-stroke ATV, while the higher price range is going to be for 4-stroke ATVs. Fuel: Fuel tank capacity is 3. Yes indeed, as long as the turbo is mounted after the cones to the expansion chamber exhaust. Not only was this Banshee turbocharged, it also had a fuel-injection system installed. The Banshee is considered an off road ATV and not one designed for closed courses only, so they were affected by this regulation.

The hp, lb, two-stroke Yamaha Banshee is easy to maintain, ideal for dirt and dunes, readily modified, described as virtually indestructible, and often called by off-road enthusiasts as the greatest ATV of all time. The endlessly fun Banshee is one good quad. For instance the LT Quadzilla was made in and is still on the top ten fastest list. Because of its cc two-stroke engine, it can hit top speeds higher than the Raptor which is a four-stroke. In an all-out drag race, the biggerbore Raptor is faster.

The quicker revving YFZ-R will get out of the hole quicker, but the massive torque and taller gearing of the will slowly walk away from the race-ready When it comes to climbing the biggest hills, the Raptor offers a similar advantage.

ProX takes you through the major parts of rebuilding a 4-stroke top end complete with step-by-step guides for each task along the way! The Banshee is a twin cylinder cc. Both are 2-strokes but the Warrior is a 4-stroke. The warrior, being a 4-stroke has a crankshaft and a camshaft.

Im a weekend warrior, I try to ride about once or month or so, I didnt have to rebuild my shee until this year, when I checked the compression is was at psi in each cylinder So i rebuilt, I prob could have got another season out of it There are plenty of members on here that know much more than me and I'm sure them chime in but I would have to say that there are way too many variables to give an exact time.

I have been on the same top end for 3 seasons now with no trouble, but my buddy has done 3 topends in 2 seasons. I belive it has alot to do with proper set up and regular maintance. I like to change the top end every season.. Keep an eye on the compression.. Time for a rebuild. That point will vary from motor to motor depending on what the compression was when you started.

But there is soo many variables I think the 3 main things that kill properly tuned banshee motors are poor air filters, overheating and lack of respect of warm up time. The exhaust bridge might be nice for the rings, but it will damage the piston if not properly relieved and lubricated You can post now and register later.

In that form, the Banshee will walk past most s in the dunes and belt out a brain-melting soprano scream from the silencers that is unmistakably Banshee. Simply put, there is no other sound like it out there. Banshees have earned a cult following for their pump-gas power potential, with a horsepower motor running around in the dunes all year.

And if you really want to get crazy with alternative fuels, huge stroke numbers and lots of money, you can get your Banshee up over horsepower.

No valves, no cams, no timing chains—just two pistons and a chunk of aluminum to compress against in the top end.

Sounds easy, right? This Banshee started off all stock, but after the top end gave out, we decided to give it a swift kick in the behind. The kit comes with rods that are 5mm oversized, so a spec piston must be used to offset the longer rod. Vertex set us up with a set of To top it all off, the head was replaced with a Phatheads billet cylinder head.

Banshee heads and stock cylinders have a maximum bore diameter of Once it was all buttoned up, our motor made an almost-perfect cc of displacement and much more arm-stretching power. We found a slightly used Full Bore Race plastic set online, plus a billet grill and some AC Racing nerf bars, which added the security we were looking for when duning the Banshee hard. To finish it all off, Renthal came in with bars, grips, sprockets and a chain, and Works Connection supplied some bling to make it stand out.

Without a stretched swingarm, the power would come on like a NOS bottle with the valve stuck open. Huge wheelstands, a ton of roost and a lot of quick shifting and we were hooked. We actually ran into the problem of not having enough traction with the big eight-paddle tires we were using, as the Banshee routinely spun the tires all the way through the bottom and midrange until it leveled out on top and was time to shift.

This motor would only work in the sand; in the dirt or the woods, it would just be too much. Having adjustable shocks on the Banshee was a big plus, as it wanted to literally throw itself into the face of every dune in Pismo thanks to its tremendous power.
