Re: 1954 GB34

As far as I'm aware the gearbox internals are identical - it's just the clutch and kickstart that make the difference. The inner cover with the numbers stamped on is somewhat vulnerable in a tumble - the kickstart return stop gets broken out. My trials outfit and scrambler both now have GB5 inner co...

Re: 1954 GB34

Wasn't GB5 the 360 gearbox and so would have had a two-plate cork clutch with GB6 for the bigger
bike with a three-plate cork clutch. GB34 would have had a three-plate 'composition' clutch with the

Re: Question about Altette horn

Is there continuity between the two terminals? If not, the striker attached to the diaphram may need to be adjusted to allow the contacts to close. If there's no continuity even with the contacts shorted together there may be a fault with the coil which can be difficult to fix without replacing the ...

Re: Ariel Four
