  1. Hi, Yes I replaced both seals without splitting the engine. One seal sits in the disk valve cover and the other sits in the magneto plate that sits behind the flywheel. (the flywheel cover bolts to this plate) I replaced the O Ring in the disk valve cover just as a precaution even though the original looked ok. Obviously, I have been unlucky in my attempt to minimise the work as I now have to split the engine to replace the sealant. I originally thought that there was a gasket between the two sides of the engine.

    Cheers Chris

  2. I would be 100% sure that the gearbox oil is passing between the centre crankcases

    as it is only sealed by sealant as thhese engines aren't fitted with a centre gasket.

    If you split the engine to fix it make sure you use a good quality case sealant

    like THREEBOND engine sealant.

    Do not use silicone houshold sealnt.

    Cheers

  3. I have recently replaced the crank seals and also the large O ring on the disk valve cover but engine oil still seems to be getting through into the cylinder. Bike smokes a fair bit as a result. Does anybody have any ideas of what else I can do to stop the engine oil getting through?

  4. I am in the process of rebuilding the engine on my 1982 320TL. Everything was going fine until I came to setting the ignition timing. I know that it should be between 2.6 and 2.8 BTDC but I can't rotate the stator plate enough to achieve this. Can someone help by taking me through the process for setting the ignition timing as I am probably making an elementary mistake!

    Cheers Chris

  5. Help! I have just bought a Fantic 300 but it doesn't run quite right. Thought I would check the timimg etc. Does anybody know where I can get a repair manual or if not tell me what to look for in setting the timing. I read somewhere that it uses a Champion N3 plug and the timimg settings are 2.5mm before TDC. Is this right? Also I couldn't see any alignment marks when I took off the magneto cover. Any help appreciated.

  6. I rode my Ossa 350 at the Angela Redford trial this year and thought the severity of the sections was spot on. (Although the weather and my riding were rubbish!) However, I was disappointed to see that the largest number of riders was in the 'veterans on modern machines' class. Having only just returned to trials, I had expected to see a big turnout of twinshock and pre 75. Anyway, I thought the sections were well suited for both modern and not so modern machines. The clerk of the course did a good job in my view.
