Hi im new to this forum and think its a great site
Anyway i picked up a cheap polaris trailboss 250 and thought it would be a quick carb clean and i would be riding. To my suprise i found out it needs crank seals badly.
So now im wondering if there is a four stroke engine i could put on it.

 

You just have to pull the front clutch, flywheel and stator plate to get to the seals.

 

Thanks for the info. I think i will just rebuild the engine and keep it the way it is.
