Minarelli Horizontal / Vertical zuma jog crank seals

When doing a rebuild, or bringing an old bike back to like, its always smart to do crank seals. They're cheap, and easy to do. These ensure no air/fuel is escaping, or entering the crankcase. A leaky seal will/can cause major issues.

These work on all 89-11 49cc Zumas, and Yamaha Jog, Aprilia sr50, pretty much anything with a true horizontal or vertical Minarelli!
