    @ Leafman : Lately I've been pretty busy working on my blown Moto Guzzi 4 cilinder. Re your question about the oil seal conversion kits I produced and sold : there are pics in post nr. 1967.

    9triton the seal is a 14-24-7 viton seal as the viton is better at the higher temps. The 24 mm outer dimension is used with the bush removed from the crankcase cover and a retainer plate over the end of the seal/bush recess. I screwed this down using 3 fine countersink head unf screws as i couldn't find metric. (Redsingle used 3 mm metric if I remember correctly) These are set in the material around the perimeter of the old bush.
    As usual I didn't take a photo, but i might have a retainer that didnt fit quite right to show. It is important to make sure there is plenty of clearance between the retainer/screws and the nut on the crankshaft.
    It would be more elegant to fit a seeger ring or similar internal circlip, but it is machining I cant do in my w/shop.

    I cleaned up the 'quill' on the end of the crank as best I could and set the seal and retainer and put it all together and it will hold enough pressure not to trip a 10 psi/.8 bar oil switch light for about 10-12 seconds after turning off the engine.
    give me a ring if u want 043934485two

    Yes, I use 3 mm countersink screws ( drillsize 2,4 mm) in my kits. No need to wory about clearance between screws and crankshaft nut : I measured 3-4 mm clearance in 2 cases.

    Wow

    That sounds interesting. Are each pair of cylinders firing together?? Sounds sort of like that.

    Engine is made of 2 V35 blocks, with an Eaton M45 blower. The 2 blocks are on 360 *. Pressurised carb is a SU HIF 4.

    slightly off topic, for german speakers,
    my le mans 2 is featured in the latest oldtimer praxis mag.
    weird to see your own bike on the front page of a magazine.....[​IMG]

    Hey, I have a non-NF question based on a discussion with another friend.

    Do any of you know of a 4-cylinder two-stroke motorcycle that was ever put into production?

    My friend was under the impression that he has seen them but I think he is recalling the big 3-cylinder two-strokes from the Japanese.

    Maybe there was a race bike like that but I cannot recall a 4 cylinder 2-stroke.

    Yes, that was a V-4 I believe. Never imported into US.

    He was talking about a straight transverse 4 cylinder.

    TZ 700/750, perhaps you remember Kenny Roberts flat tracker and its subsequent banning by the cry baby H-D supported authorities.
