Use of the old gudgeon pins may help as this is usually where most of the extra weight is. Apparently much money can be saved by not taper boring the pins.

Re: Clutch basket rubs on inside top of dome

I think that your bike has never had the clutch so far back before you fitted the oversized chain and there is no spare room in the chaincase so if anything is slightly out of line there will be trouble.

Re: handlebars

Re: Baffled

Draganfly have made baffles to the original sound and style, with, if I remember correctly, assistance from the club. These have been fitted to all the silencers they sell for at least 10 years. The baffles are available separately. I have no connection with the named establishment other than being ...

Re: Steering damper order of assembly?

Insert rod into the steering stem, retain with the pin through the bottom yoke. Note do this before fitting mudguard! Assemble damper parts as per 1951 or later parts book as they have exploded views, assemble upper parts using the same method.

Re: The story of a 1928/29 Ariel LF 250. Part 1.

Neal, you could save some money and just paint is as it was originally. Chrome didn't arrive on Ariels until 1930 when they went a bit mad, no doubt they were proud of their recently installed chrome plating plant.

Re: One of the earliest 1000cc Square Fours
