has anyone or know someone that has taken a street bike engine(example)gsxr 600cc,and put it in a quad frame?i know there are some people out there who have done this conversion,and succeded.i've seen the video's.my question is.......does anyone know what problems i may have.cooling,fuel injection,correct engine placement,frame length,width,etc......maybe its a time consuming project,but i am willing to try it.i have wanted to do this for a long time,and may have found a rolling chassis banshee,and a 2000 750cc street bike motor.

 

the wiring is the hardest, mark every wire and plug as you pull it from the donor bike

 

what kind of 750 did yoiu find. the banshee is a great frame to start with but its kinda short. i helped a friend put a r1 engine in his raptor after he cooked the engine. like wizzard said mark all the wires. make sure your sprockets are lined up when you mount the engine or your gonna have problems. if its fuel injected watch the placement of the computer if you plan on riding trails as sticks can make it a long push home. use weather tight connectors where ever you can to keep water and mud out.

 

thanks guys,

donor bike will be a kawasaki zr 750,if the deal goes through............

 

I personally haven't put an engine in a quad, but I have built one around a small track car.


I have helped a friend fit a busa engine (which we then turbo'd) in a modified Raptor frame however.
Potential problems you may encounter are (but are not limited too!)
Getting the engine to fit in the frame
Getting the ancillary items to fit in the frame (primarily exhaust and intake) - we had to weld a new exhaust manifold anyway for the turbo.
Drive - a sportsbike's drive is hugely off-set in comparison to that of quad.
Wiring - we ran a Motec M800, because we wanted to Turbo and custom tune it... very expensive, but over 300hp at the rear wheels can be your result
Cooling - although in my opinion this is one of the easiest to overcome. We got a small car radiator, bent up some aluminium tube, and some standard rubber hoses.

It is a complex project, but if you are resourceful, and can fab a little (and know the basics of wiring) not beyond you.

 

Never did a 'quad', but, a couple of my neighbors and I (well, I had limited abilities then, only 14 years old) built a go-kart and put a BSA 650 cc motocycle engine in/on it.

That 'puppy' would FLY!!!!

 

wow!!! that thing is amazing!!! and i want to drive it,lol.

sounds good.......i know i will run into a couple complications but it will be worth it!!

 

if this quad turns out........i'll def. consider a kart also!!

 

how does mounting the motor work?

 

how do u mount the motor from a katana 750 to a yamaha banshee?

 

how does a street bike motor mount on a qaud

 

I would think using a cart as a base would be a lot easier to mod than a quad ... More room ...

 

I'm making one right now . I'm going to make one of these street leagl bumper car .. The 750cc motor is too much power ,I wish I had a 500cc motor..

 

Looks great!
Try putting a restrictor on the intake if its got too much juice!

 

I see streetbike engined quads (mostly Banshee frames) often at the Oregon dunes. They fit pretty well, since there's a fair amount of room, but most need to bend the upper frame tubes upward a bit to make room for the head. It actualy makes sense if you're sand dragging or hill racing, since they make a ton of power, are very reliable and cheap to boot. I built a killer Banshee years ago and had a full-tilt JD racing motor and nitrous and I can tell you it was nothing close to inexpensive. It was reliable and an absolute rocket, but affordable it was not.
