NICE!
I bought this kit last year and it has been a champ! Installed on otherwise stock 78' NC50 Express and greatly improved acceleration and top speed! I weigh 278 and it carries me 28 mph! And on a lighter note use a custom made gasket and you can keep stock exhaust if you want. Unless someone donates you a performance exhaust...

Mehh
Pa50i overbored. Rings busted when checking the ring gap, had NO elasticity to them and could actually be heard "crackling" with any type of pressure on them. Justin was awesome and sent new rings though...plus one star! Piston was super cheap quality and blew a hole through it within 25 miles, not timing or tuning related. Just very crappy pot metal. Cylinder is cast iron, so cleaned up super easily to new condition with a ball hone. But another $30 later buying a piston from another vendor to make it right... hence my 2 star mehh rating. If the pistons get changed to kstar or a better quality, it gets 4 stars. Til then 1 star..well 2 because moped division is very honest and a great overall vendor.
