GP1200r to GP1300r
I have a gp1200r that has a blown top end... The front two cylinders are shot and i want to upgrade to a 1300. I have found the top end part number 60T-W1130-01-8S for the cylinders and i need to know if thats the right one. From what i understand they have to be powervalve cylinders? Is this common and does it run well with carbs? Any advice?
I am new here and thanks for your help
Mike

Simple to do, everything just bolts on
You will need the complete GP1300R top end from a 2003 or 2004 ski
cylinders
pistons and rings
power valves
cylinder head
You will also need to change the jetting
Makes for a cheap upgrade because you can easily sell the GP1200R parts that you no longer need

I have 2 good used complete 1300r cyls with pistons, rings, and valves. Find one more and you are good to go.

It will probably be cheaper to have your existing 1200 cylinders punched out and head rechambered unless you can find 3 good used 1300 cylinders and a head. Remember the power valve blades too. For the cylinders, power valves and head it will probably run $1500+ for used. Take some pics and post them. Lowell is fair to deal with in those instances. He machines the powervalves and does everything else.

Like I said by the time you find all the pieces it will be easier and cheaper to get the 1200 punched out.
