Re: Replica long twistgrips

Thanks Alan

I'll give up my search then. Replica 6" rubber grips do seem to be readily available so I might have a go at lengthening a standard twistgrip like you did.

Replica long twistgrips

Does anybody know where I can get a decent replica long twistgrip (to go with 6" John Bull No 16 rubbers)?

Re: 1948 Iron 4G Coil Ignition

Chris, Is the small screw that holds the rotor arm taper to the top of your distributor shaft tight? Silly question but it caught me out and, if the screw is loose, the rotor arm taper can slip to the point where the rotor arm points to the wrong cylinder. It is surprising how far off the rotor arm ...

Re: Layshaft bushes for 1st and 2nd gear 1951 CP

John, Nev - Thanks for the replies. This CP box was on a 500 single that looks to have been used with a sidecar so probably had quite a hard life. When I dismantled the box it was virtually dry and the grease that was in there was way too thick to get anywhere near the gear cluster. Everything turne...

Re: Layshaft bushes for 1st and 2nd gear 1951 CP

I have revisited this old thread because I have the same problem with my 1949 CP box. The 1st/2nd gear layshaft bushes are knackered and are is not listed as a seperate spare part by Ariel. My layshaft however is in reasonable nick and has a very good speedometer drive on it so I don't really want t...

Re: My 46 SQ4 is finished - or so I thought

John, I was lucky, the flange on mine had been repaired previously with an aluminium insert threaded into the timing case. I simple found an oilseal of the right diameter to screw into the existing thread. Whether this will work in practice remains to be seen. thread.jpg If you are going to the effo...

Re: My 46 SQ4 is finished - or so I thought

John, The flange itself is only part of the oil seal mechanism. The inside diameter of the flange hole is such as to give a relatively close clearance with the magneto sprocket. You should find that there is an external thread on the back of your magneto sprocket. As the engine rotates this thread c...

Re: Wheel rim alignment for for later tele forks

Paul, The fork stanchions on the 1946-48 forks are positioned closer together than on the 1949-onward forks. This requires a longer front spindle, amongst other changes. Without a set of early yokes to compare, I can't be certain what the difference in spacing is, but I think it is either 1/8" ...
