400cc 250r!
#1
i feel like an idiot. yesterday i was looking around on the net and i came across a site that had a 400cc 250r kit. it was the top end off of the pilot mated to the bottom end of a 250r. it was badass, but like a moron i forgot to bookmark the site. i was wondering if anyone has seen the conversion or knows about the site i just talked about. it looked like it would give the 250r some major *****!! thankz for reading . please reply

yes but why??? yes i know more power. It is a time bomb. All major big bores are time bombs. I had a 300ex punched to a 405 bt TC you would have to pull the hed every couple of races to see how the insides are doing. If not properly maintained Bye Bye $2500 motor. PSI makes a 425 motor and the kit is close to $3000. i still think you can build a 250r motor with a 330 that will work just as good with out all the hassle. Also i heard PSI has problems with the motor overheating.

That FTZ 400cc 250R uses a Honda Pilot (the bigger Odyssey) cylinder and head. They modify the 250R lowerend to make it work.
I haven't heard anything pro or con about that particular motor, but I have heard many good things about FTZ.
There is a guy near me who has an FTZ 265 (which uses a new Honda CR 250 cylinder) and it absolutely RIPS!!!
