  1. 1974 Ossa MAR

    Bennyonions posted a topic in Introduce Yourself
    Hi All, Recently acquired a 1974 Ossa MAR, the whole thing is wreck so have stripped it right down. In short I cracked a crank case separating and am now looking to replace the right side case. I bought a nice cheap pioneer case but the only difference seemed to be the size of the crank webs as this chamber is 5mm smaller in diameter than that of the MAR, I have since bought an MAR case 1972 and again 5mm too small. Can Anyone tell me what year/model may correspond with the size difference other than 1974? Engine and frame match. Put me out of my misery please.. Benny
