Default fitting a polaris scrambler 400 cyl on a 250r bottom end.

has any one done this? if you go to the oregon dune fest in the duning section of atvconnection.com and look for something called the "hondaris". it doesnt look like he had to relocate the studs. also what piston did he use? a piston from a production big bore kit and he just bored the cylinder? any thoughts on how difficult this would be? how reliable?

Ihave always heard them being called a Polonda. People have been doing this for years.
