    FS Mark Hahn cyls AND WTB 1300 Cyls. Read for more info.

    Well, today i had a catastrphic loss on my #1 Cyl. For those of you who have followed the Mark Hahn reborn build you know what cyls I am referring too. All was running good and I suddenly lost about 2000 rpm. I limped it the last 500 feet or so to the ramp and when i looked in the hull I noticed a lot of oil and water on the throttle bodys. I grabbed a flashlight and saw that the #1 cyl that I had professional welded (it was found to be cracked when I pressure tested the motor) had failed. Big crack in it and actually came out in 3 pieces. SOOO Im done with this setup. Im selling the 2 remaining good ported cyls with pistons, rings and wrist pins and looking to replace with a stock 1300 top end. let me know what you have for sale!!

    Gas valves NOT included if I sell the other 2 cyls.

    This is a good reminder to all Never weld a cyl. Better off to get a core and replate it or good new or used one. Just too much riding on that repaired crack.



    I am sorry to hear about this and hope you get that rebuilt and running good numbers. Too bad the things you put hours of work in last only a few mins. It happens to all of us.

    Well considering I have 2 good ones with piston, wristpin, rings and bearings I would say $750 shipped within USA. They are ported cyls and would work great on an 800 machine.
