Hi all, please excuse my ignorance my ignorance with this question.

I'm rebuilding a 1974 C70, needs a new piston and rings - looking on eBay ive come across a number of listings for cylinders and pistons combined, all the listings are for flat top pistons, the original is domed.

I don't know the length of the flat top pistons and whether outfitting the engine with one of these new cylinders and pistons will work as I want to use the original head. Anyone have any experience here? Anyone know how much the heads changed across year models?

It's best to stay away from ebay in this instance! The heads/pistons and rod changed in 82. Go to dratv.com and pick up a piston kit for $26.99 plus shipping for a c70. His site explains a lot of details, and I am sure you will learn something about these bikes and the parts on his site, unlike ebay sellers!
