so I just built a gt5 stroker motor. It has a pk top end cyl slant head and piston. the wrist pin height is 4 mm lower on the pk piston than the skyhawk so made up the diffrence with a spacer plate and 2 base gaskets adding the 4 mm I needed. this motor is the fastest one i've ever built it has some serious pull and it revs way past stock specs. the only mod i did to cylinder was widened and tapered off the exaust port. chamfered the other ports and added a pirate cycle -mm billet intake and jetted the carb leaner on the main. look out also have the pk skyhawk clone ready to go in a bike when i sell a few of the ones I have..
