Don't think the 1250  bottom will fit straight on the older water melon Heads.  I could be wrong tho..

1250 Barrels work with the watercooled head and cases - crank and cases are a little different because the 1250 runs the charging system off the end of the crank rather than the jackshaft with the starter and alternator. Pin size is different, so probably have to do a rod swap or find suitable pistons..

i actually think that the rf900 is good because it doesent have the torque of the bigger engines. I dont think it will handle more powewr particularly well. maybe a little more top end would be nice. just my opinion
