Found in a box of saw stuff. I believe this is a 365xt cylinder. Good condition and complete with boot, clamp, vibration spring, and compression release. The transfer covers are there and good and there are no bolt holes stripped. No broken or cracked fins. The cylinder walls are a little discolored in a couple spots but no scratches or transfer. Look at the pictures. $78 right to your door. Some say you can make this into a 372xt by grinding out the transfer dividers. Both 50mm as is this one.
