Installing an over-bore kit will give you at least 10 more HP. This involves having the cylinders bored out by a machine shop, then installing new, larger sleeves, pistons and rings, etc. I can't even guess what it would cost, but it is probably cheaper than buying a bigger tractor.

thanks DOUG. I WAS CHECKING THE SPECK'S ON THE MF 65 THERE WAS A HIGH ALTITUDE MODEL THAT HAD AN 8 TO 1 COMPRESSION RATIO AND THE L-P MODEL HAD A 8.75 TO 1 RATIO. THE STANDARD GAS HAD A 7 TO 1 COMPRESSION RATIO. I DONT KNOW IF THE DIFFERANCE WAS THE PISTONS, OR IN THE HEAD ITSELF. MABY SOMEONE MIGHT BE ABLE TO LET ME KNOW.AND WHERE I MIGHT FIND THE PART'S. THANKS.
