• I bought a legitimate stolen recovered engine from a police auction place, from a KTM LC2, some unscrupulous bastard has ground off my engine number, but also the numbers from the bottom of the barrel.
    I have a 3BN cylinder head.
    Which barrel am I likely to have ?
    Which barrel is the best for power ? Don’t care for reliability I want power.


  • It'll be a 3MB cylinder. You want the 3MB head to go with it. 3BN heads are restrictive.
