hey i am thinking about getting a blaster roller that has a ninja motor but it needs to be mounted. so what would it take? should i just sell the motor and get a blaster motor? i cant weld so how much do you think it would cost to get someone to make a mount for it?
 
Depends entirely on the ninja engine you're talking about using and the amount of fab work you feel like taking on yourself.

There have been a few street bike swaps into blaster frames... namely a ninja 250 and 500 engine. The bigger ninja engines have downdraft carburetors on top of them which are configured to be fed from the airbox directly above. On a blaster, that area is part of the space frame, and the fuel tank. Difficult to cheat the fuel tank and frame up there...

The blaster frame may not actually be your best bet for an ATV to fit a street bike engine into. The frame is inherently shaped wrong for a streetbike motor (which tend to be square instead of the quadrateral the blaster frame is made like). Perhaps a better starting point would be a larger 4 stroke quad frame (warrior or 400ex).

If you do decide to take on a street bike engine swap, take LOTS of pictures. We love pictures!
 
There's alot to deal within a motor swap. You have to make sure you have the motor lined up just rite or you will be throwing the chain all the time. You have to make sure the mounts are designed and welded correctly to handle the power. You will have to fab up the cooling system. I think you will have to cut and modify the frame for room and fab up a way to re mount the gas tank. You have the electrical system to deal with. You have the exhaust to fab up. If you don't have the skills or the money to have it done, then get a Blaster motor. There other small details I didn't even mention.
 
i would try a warrior frame for a street bike swap. just more room to work with. although there is a number of large engines swapped into blaster frames so whatever you think

I agree on the Warrior frame. It would make it easyer to do the swap and if you screw it up, it's only a Warrior. No big loss.
 
depends on what its worth to you.

There a good start. I am by NO MEANS near fully complete and im several hundred dollars and many weeks into it and I do all my own fab work and welding... thats all just cost of materials and parts needed (although admitedly i could have saved a bunch a money and left some things off but whats the fun in that?).

Its certainly not a task for the weak hearted and will eventually take its toll on you and your sig other (if applicable) which in turn takes more of a toll on you. But if its what you like doing or are willing to invest into something of your "own" so to speak, its incredibly rewarding. My only regret is not going bigger on the motor, but im not sure the fram can handle much more with my riding style (if it is unbreakable, i can break it).

I say if your willing to get incredibly frustrated, pissed off, injured repeatedly, burned, cut, scratched and run bankrupt, DO EEET! it is a lot of fun and you have something totally unique to you and if nothing else, you can look at all the other suckers out there with their stock ones and smile a bit cuz of it.

but a word of caution (as if this all isnt a big caution), PLAN IT OUT! PLAN IT OUT! PLAN IT OUT! make sure everything is strong and clean and squared up. you can get seriously hurt or worse if the thing comes apart on you at speed (ask how i know this).

Not trying to discourage, just being realistic.

Good luck and i say go for it!

It would take a plasma cutter a decent welder some chromoloy tubing 3 Rabbis and a priest plus an ambulance to catch you when that thing twists apart
