well if you have not done them on any two stoke toys though the years i would not recomend it.

 

Hardest part is the needle bearings. Get the caged ones to make it easy on yourself. You will also need a new base gasket and a torque wrench. Siphon out as much anti-freeze throught the bottle to make less of a mess. Also find a friend that knows how to do these things and some

and goodluck with it. -Grover
