Banshee Engine Swap

Welcome! ... Don't pay any attention to the negative BS... More talkers than doers on the net..LOL... Follow your path! Start a thread and keep the pix commin... I'll enjoy watchin!
Good Luck

my comment was meant to help him out in the long run.
mainly because he is going to want better suspension for the extra weight from the engine and other things.
also have you thought about where you are going to mount the rad?

The front shocks are off a banshee, so I'm sure they'll handle the weight. The arms are +2 +1, and there will be +4 in the rear. If this thing is fun at the dunes I will be putting Elka's on it. The radiator (250r) is going in the front bumper.
 
banshee front shocks barely work good on a banshee. with +2+1, it will be soft.

if you are going to spend all this time on it, you should just do it right the first time and get some decent shocks on there.
 
I found a banshee here in town that is being parted out , I was thinking about buying the whole quad for 275.00 its been sittting a long time . I'm mostly interested in the motor , whats it take to swap the shee engine into the blaster frame? The shee is pretty much complete with a bent frame and broken swingarm . whats everyone think?

I think this is a totally ass kickin Idea and i wish u the best of luck!:D

ive seen a kfx 250 motor in a blaster. thats liquid cooled, he had the radiator at an angle toward the right fender w/ a special bracket of course. you can pull it off man. my buddys looked pretty sick and so will yours:)
 
just when you mount the rad. make sure you get a guard for it. shees have them up high and since yours is low you wanna make sure a rock doesnt fly in adn ruin your day. word to the wise
 
it's sound's mad :o it would be a lot of work 2 do BUT if u think u can pull it off by all mains I:I go a head wit it It will look mad when it get's done if it's get's done and will atract a lot of atenshion :D i think u should do it but then agan i'm only 13 and a bit of a dreamer :L
 
Anythings possible with new motor mounts that's how I shoehorned my motor in.
If you really dig Blasters, you grew up on one, or you just KNOW how to ride one, I think it's a really cool swap.
Banshee motors parts will always be around and the motors still fetch good money.
 
I've seen quite a few engine swaps where people just use a hacked up stock header on the swaps of a two stroke. That kills power big time.

You nailed it.
Passion motorsports is currently designing a banshee pipe with some very sophisticated software.
To put it in perspective it takes his high end computer 4 minutes to calculate 1 sec of what goes on in the pipe.
If you think you can just wing it with some cobbled together contraption well..........

There are several books out there (eg: A.G. Bell's 2-stroke tuning book, The High-Speed Two-Stroke Petrol Engine by Philip H Smith, GP Blair's The Basic Design of Two-Stroke Engines) with formulas for figuring pipe designs, or you can tweek known designs to get a few more RPMs or low end torque. The first pipes were trial and error. Once you know what each part does, you know what to modify to get the results you want. Even after that big high end computer crunches its numbers, some one has to bend pipe and I'll bet changes are made.

Just DO IT. Learn, then make it run with the best information you've got.

My first tuned pipe was on a 74 DT250 with info from Smith's book and it turned it from tractor to pony. It is nearly rocket science but it is backyard do-able.
 
Correct me if I'm wrong but wouldn't the frame need massive support work to be able to hold together under that kind of power? Theres a Blaster on CraigsList with a KTM 125SX motor in it and the frames cracked and bent from the power.

I don't know for sure if the frame would crack.
I used to crack frames on stock bikes when I was younger but in spite of putting on more weight, I seem to have gotten easier on gear as I have gotten older. My best guess as a machinist and industrial mechanic is that with my driving style I will have no problem. The fram looks stout enough. If I were making jumps and red-lining all the time, maybe not.

The KTM125 is 40 hp and the 250/300/380 are all between 50-60 hp with mainly a difference in low end torque and RPM limit. My son and I actually have a watercooled DT200 and briefly considered that swap, but heck, that bike works!

I had a 660 Raptor for a few years, but I am mainly a 2 wheel sort of guy. I go out off-roading with my buddies on their 4x4 "funeral carts", and have no desire for one. I liked the speed of the Raptor, but it was a bit heavy for some of the trail riding I like to do. The light weight and simplicity of the Blaster appeal to me. I bought mine not running and it needs a crank and bore, and I happen to have a couple spare KTM motors available...

Looking for some hints on:
what type of rad to use and where to put it,
details on how to trim up the swingarm to fit the wider KTM motor,
suggestions on a rear hydraulic brake, Banshee brake work?

I am using the search function but I end up spending many hours of sifting without finding much technical stuff. If anyone can point me to some good threads, it would be nice.

For brakes get with AWK for a GSXR setup. Everybody who has them says they are the best setup ever. I have not used them yet. Bought a complete GSXR rear setup on ebay for 35 shipped. Gonna relist and sell the rearset to get some of my money back. Bought the brackets and hardware from AWK. I think he also sells complete bolt on ready sets if you dont wanna mess with putting them together yourself. Good luck. Will be a pretty interesting build.
