185 pistons

[ratvespa]

Im rebuilding a 185 Ive had for awhile, was digging around parts I have accumulated for it, and came across a new piston..only difference is it's a dished pistons, the engine I just took apart has a domed (higher comp) piston. also the bore seems to be about 1mm smaller. I also have a few spare jugs and pistons I found, one is dished, and the other is domed...whats the deal? what models got what?

also I was hope'n to swap the cam chain guides without removing anything from the bottom end...don't look like the case, I need to pull at least the stator/rotor.

All the 185-200 model atc's came stock with the dished style piston from the factory except for the 200x it came with a flat top piston . if you have a domed piston its aftermarket .
