COMPRESSION TEST RESULTS

Well, after sending off for that 12mm adapter for my compression gauge, I'm pleased to report that it was a waste of money, LOL. The readings on both cylinders was a whisker under 180psi which is pretty amazing considering that it's a 31 year old engine and it should be 185. WOW!


So I am now a much happier bunny knowing that I don't have a broken piston-ring or a sticky valve. I can now focus elsewhere and I have almost no doubt that the problem is electrical based. I just need to fit the carbs back on (with the new inlet rubbers which arrived today) and start looking at the alternator and/or pickup-coil.

See you next time!

    That's great to hear. It rules out a lot of possible problems :)

    Hi guys!

    I have been following this great blog for a while but have now realised I won't have time to finish the project I started in the autumn.
    I have 2 Honda CB250N Superdreams from 1980 and 1981.
    I bought them last autumn from a guy who had them parked up in his heated garage for the last 10 years or so. All there is needed to have two complete bikes is a new exhaust on one bike and a battery for both of them. I just got them both running and the electrics working again.

    My problem is that I can’t store the bikes where I live and have to drive 45min to get to the bikes which are in a friend’s garage.

    It is the perfect project!

    Look up this ad on Gumtree to see pictures.
