I want to put a 900rr motor on my 400ex and i was wantin to know what kind of power they put out. How much could i get one for??

 

115whp stock. Can be modded faily easily and inexpensively to be comparable to a stock 954.

Price: not sure. Just check on ebay and see what pops up.

 

i would suggest running a fuel injected motor. believe it or not, the conversion will go easier with an fi motor. plus fi computers have more of a spark and fuel curve making more adaptable to whatever enviroment you ride it. i've built 25 or so of these machines. i'm trying to upload pics of one of my machines. it's a 400ex(actually a '89 250r w/400e plastics) powered by a '01 cbr 600f4i motor. great all-around machine.
