Problem with installing big bore kit on a gy6 engine?

Question

I've been following a installation guide at scootdawg.com with no problems until I get to the cylinder which won't slide off as it shows.

It looks like to me that the piston has rusted could this cause it to be

stuck?

I advice on how to remove the cylinder safely , it doesn't matter if I ruin the gasket as I have another. I may have bitten off more than I can chew attempting this but now I've got this far I gotta carry on.

Answer 1

if it's rusted, go with a sledgehammer and a chunk of wood...

ease it off with a few "love taps"...

Answer 2

are you sure all securing nuts are removed if so fill the cylinders with oil and leave for a few days  then try gently tapping the cylinder upwards if it still wont budge try gentle heat on the cylinder but be careful  for obvious reasons

Answer 3

your doing well....just smack it with a big hammer...it will come loose..
