Do they sell a big bore kit for 84 ATC 200s? It is my work horse and more power to pull all my stuff around would be better.

well, powroll sells them for the 200x, so it should work for the 200s. if you want more power, a wiseco piston, cam, exhaust, and carb should be enough. but it depends on how much you want.

Not really much of a big bore kit.

Powerroll's 66mm piston pushes the displacement from 194.66cc to 197.65cc. But with the stroked crank you can push the stock piston from 194.66cc to 214.87cc or whopping 218.16cc with the 66mm piston.

The real gain is in the increase of compression with the 12:1 piston and the 6.0mm crank. Combine that with the high lift race cam for some serious horsepower, or even go against recommendations and run there torque cam to have less overlap and raise the compression even more. Downside is you need high octane race gas.
