how to install a 70cc kit ?

hi all. Just got a Athena HP 70cc kit. Its not a new kit so iv ordered a new set of gaskets. Does anyone know of any guides of videos to fit these kits with the engine still in or know how to fit them personally ? also anyone know how to get the piston ring in with a compressor tool, thanks

 

well its easy to do with the engine still in just follow a video
but you dont need a compressor tool to fit piston rings :/

 

cheers mate , also yeh I meant how do you get the rings in without a tool as I haven't got one.

 

As said, you don't need a ring compressor tool, you just feed/press them in the barrel carefully.
