I've asked several times why no one puts these motors in our rhinos.. I hear of people using R1 motors all the time but it seams it would be much easier to use the apex motor. Its the same top end as the R1 but has a cvt clutch rather than a gear box. Im no fabricator but it seams to me that all you would really have to do is line up the clutches so it wouldn't blow belts and you would have a bad ass machine. If the 4 cyl motor is too large, yamaha also makes several models with a 120hp 3 cylinder motor that might fit better.. There are tons of them out there and they should be easier to get and cheaper than R1 motors since usually the body of the snowmobile falls apart far before the motor.. Like I said, I can't cut or weld but seams that someone who could would be able to make a bad ass machine for much less than the traditional R1 build.
