LD80 CYLINDER

THIS CYLINDER IS FOR A 66/80CC  MOTORIZED BICYCLE 2 STROKE ENGINE. I have tried quite of few different cylinders and in my opinion these are the best and have the best casting.

I also port these out and clean them up updating pictures soon this will allow more air and gas flow and will make it a smoother running engine i taper/chamber the ports and clean out all the gunk china left behind you should do this with all stock kits in my opinion. can do any port timing you would like 

please if you would like your ld80 cylinder to have a specific port timing please lmk right after purchase and i can do that i usually do 176 exhuast 124 tranfers with a 26 blowdown which i think runs the best but it is up too you.
