| Has anyone tried adding the head and carbs from a 660 Raptor on their Rhino? Checking with Yamaha I found that the cylinders, head and cam have the same numbers. My Raptor shows 38 hp at the rear wheels on a dyno. Seems like this should be an easy bolt on hp for the Rhino. I didn't check on the difference in compression ratio but that can be corrected easily. Thanks | |

| If they have the same numbers then they are the same so why change them. | |

| At the crank, the raptor is 45HP vs 41 for the Rhino. Different cam and intake and exhaust. Raptor has 2 carb setup. 2-33mm Mikunis. Reason for 15HP difference at rear wheels is manual tranny and chain drive versus CVT and shaft on the Rhino. CVT's are real HP eaters. | |

| An easier way would be to build a 686. Probably much cheaper too!!!! |
