i have an airsal a55 70cc kit, it is used.
my oil injection failed and the piston is shot. i just put my old cylinder because i had no money. the cylinder looks fine, probably doesnt even need a hone, but im sure it wouldnt hurt.
in looking to get 70 for it shipped. it comes with the head and the cylinder.
