just got a 55 air injection with a toasted piston and cylinder for free. It's an 46mm with a decomp valve. I'm not going to waste my time on trying to save the cylinder it's gone. Just got off ebay and saw cylinders kits from 23.00 to 150.oo . My question would you spend the extra $ for the Meteor kit. Or what kit would you get? Sorry no pictures because i run over my cord with my chair.
