760 bottom end with 61x top end

[bored&stroked]

A combo I run across quite frequently is a 61X bottom end with a 62T top end on it , what that means is someone yanked the 62T engine , put the 61x cylinder on it and cobbled what was left back together and sold the ski, they actually run quite well like that though and in a sitdown ski you would barely know the difference.

I've ran that combo.
It also had a 64x ignition in it lol
I had enough parts to make a running engine. They just didn't exactly belong together. Worked fine.
