    Sleeve... make it or have it made... Its little more than a pipe with a lip on one end..
    Get a length of "maganiese iron" ... yer can buy blanks... or fined a
    used sleeve from a diesel engine thats big enough to re-machine...


    near the bottom of this list is DR400 E,S sleeves for 440cc big bore...
