well I pulled the motor out of my 01 Gp1200r and found a custom hole in the side of the block with the rod hanging out. The head looks fine but the case/crank/ect are toast. Here is what im looking to do

I have a 04 R12x that has light mods but blows the gp1200r out of the water. Im looking to make this gp1200r keepup with the aquatrax but not go crazy on prices.

I need some basic help as to what I should do to this ski. The ski ti bone stock and since I need to do a motor, I figured Id mod it the way I want it while its in peices.

Should I get a bone stock reman motor for a grand? or used one for a little less? a used modded motor??

thanks guys!!
