Re: Changing oil with an anti-draindown valve fitted

If you get an air leak between pump and anti draindown valve, or perhaps just air between pump and anti draindown valve, the anti draindown valve is likely to fail to open. A slightly slack union caused by a fibre washer "bedding in" caused me to throw a rod on my 1954 KH so be warned. If ...

Re: Balancing individual steel flywheels

I am with Nev on that one. The mainshaft should be easy enough to replace but the flywheel will be a problem, whether finding a replacement or sorting out the current one.

Re: Spotted at Shepton

You should have bought the Square Four petrol tank. Its the one unique to 1953 and someone, somewhere is desperate for it !

Re: Noisy VH engine - Roller mains

The datum for crankshaft end float on a 1936-59 single is the ball bearing on the drive side. I am surprised that the roller used in place of it doesn't show damage. Has the inside of the timing pinion worn away the timing case?

Re: Upcoming auction in Goole - two 1930s Ariel singles

The forks on the 1934 bike are bent. Look at the rear tube top section above the friction discs.

Re: Upcoming auction in Goole - two 1930s Ariel singles

If I am not mistaken, much if not all of the forks on the 1932 bike are 1934 onward type so there is not a lot of 1932 material on the bike.

Re: Ariel rally Československo 2024

Sorry to hear of this setback. We will allow an extra week for you to be fighting fit again.

We can supply a bike for you to ride ...

Re: Wanted front Altette horn bracket (6155-35)

If you look at the 1948 Twins leaflet on the Club website it shows a left hand side view of the KG, with downswept pipes. The horn appears to have the right angle bracket and be fitted to one of the front engine plate studs.
