Can this be done without pulling the pistons and or doing anything to the transmission? Can I unbolt the connecting rods and pull the jug to replace the gasket under the jug? Is there any other parts I should change when I have it apart? Like con rod bearings or a different cam chain tensioner?
It isn't a big job to strip and rebuild the entire motor.
The actually strip and reassembly time for a clean motor with the correct tools (without doing things like a valve job etc) can be done in a day if you are experienced.
You can replace all the bottom end gaskets without splitting the cases .
The case halves are sealed with RTV (no gasket).
You cannot unbolt the con rods as the crank is a pressed up roller bearing item like a 2 stroke.
You will have to pull the head and block to renew the head and base gaskets.
Depending on mileage you may have to renew the cam chain and guides .
