Will a 400 engine go on a 250 frame? They appear to be basically the same. Are the swingarms the same also? The 400 is a concentric and so is the 250.
I did a search but didnt have much luck
Thanks

 

didnt HPD stuff one in there once? or was that a 250r?.....anyway if ur talking about like a TB frame im sure it would with a llittle extra support.

 

Yeah trailblazer.

 

ok. I refiened my search. Found what i wanted to know. Except for the swingarm swap. I cant see the 2 machines being that much different. ??

 

The only real obsticle is the engine mounts and mabe some reinforcement. There isnt much of a wieght difference the Sport and Scrambers are about 40lbs heavier than the TBs and i think thats mostly the cooling system and some other parts that are more heavy duty. Which leads to mounting the radiator makesure if u do perform this that the radiator is secure, also all the mounts are strong enough, depending on how powerfull the motor is. U dont want that torquing out of place.
