I need some help on this popular swap, I just picked up this MINT ttr90 frame, with rolling chassis; and also came across a factory raptor 700 cc engine.

What do I need to do to get this right?
PLEASE HELP!!!!

 

I may be wrong but it doesn't seem like that will ever work.

 

are you sure?? I've put a lot of money into this.
I've been told it has a Dual Overhead Cam.

 

No, I'm not sure.

 

JMO but you haven't put a lot of money into it, you've just plain thrown it away.

Do you seriously think that frame is going to take the torque twist the raptor motor will put on it? And if it does, what's going to keep it from snapping when it lands?

There's probably a good reason you don't see 700cc pit bikes.

 

You just need a hacksaw to gain a little extra clearance and use some duct tape and large washers to put motor mounts on the frame that line up with the new engine. Also, I would just use one of the overhead cams so you can shave some weight.

 

You think?

Nothing a couple of properly placed gussets and braces wouldnt cure.. big gussets and braces...

And if he brazes it together instead of welding.. it will flex and not break...

Im sure someone has built one

 

I'm sure somebody has.




May they rest in peace.

 

Gorilla Tape would be better..

Should rev higher too!!

 

Somewhere out there, in a parallel universe, someone is trying to put a ttr90 motor in a 700 raptor frame.
