I have been going through my engine parts bin that I haven't looked in years and found a Super Tigre liner and piston assembly, brand new still in original container the only number on the container is 02190693 ink stamped on the back of the label I believe from the factory. The piston has two grooves for two piston rings, can anyone identify this from the numbers I gave and the fact the piston uses two rings. If it can be identified from that number and information the next question, would it be worth my while advertising it, I have no idea what anything I have is worth nowadays. I Tried to add pictures of front and back but couldn't add the pictures because file to big.
