ok now i'm rebuilding my old engine and i need some info.

it's a 1300 case I was told it was a 1500 sp. Now that we've pulled it apart i've got some measurements. The cylinders are bigger than a 1600 tp. the piston size is 86.95 and the cylinders are 87's. so what size engine is this?

would i be wrong to say its a 1641cc??

Yep that's right, 1641cc.

that must be a nice surprise. Now find yourself a set of twin port heads and a bigger carb and you'll have a great reliable offroad setup.
