How to Install Crankshaft Seal (Without Removing Engine) *Yamaha YSR50*

How to install the flywheel side crank seal on yamaha ysr50 without removing the engine or splitting the cases. This works on both sides, the right side has more to remove but can be done without engine removal. Hope this helps someone! This works on most 2 stroke or 2 cycle dirt bikes and motorcycles that have straight seals.

This how-to can apply to many different two-cycle machines! It is primarily for the left side or flywheel side seals. But works on pretty much any straight seal. Make sure to subscribe if you haven't!

50cc ? Don't you have a left and or right side engine covers laying around

[@bearkreekboys]
