I own a 2000 Polaris Indy 500 and the Crank Bearings have given out(5200miles, bulletproof my A$$). I am not looking into spending any more money in this under powered motor.

Can anybody give me there experience with putting in Larger twins and even triples?

As of right now I am thinking of buying a 1999 Polaris 700 twin, can I use one of the motor plates or will I need to modify the 700 motor mount?

Any information would be appreciated.
