Re: Tapered roller bearing steering head

Hi Peoples; -
Please, has anyone fitted taper rollers to a Mk1 Sq ('49, solo)? - do Drags do the parts & are there any issues with the fit?
Cheers, John

Re: Different size Ansti stirrup

Just a throw in - In my experience I prefer to use the later stirrup with the threaded adjusters... the snail cams can be swines to adjust and tend to slip, particularly if the machine has a chair.. I put an add for my old ones in some yonks back... still no takers... http://forum.arielownersmcc.co....

Re: Coil or Mag? E3L or Alton?

Suggest that "Alton" might be replaced by "Iron Horse Spares" - admittedly they are more expensive - but with 300W available there is sufficient headroom to fit whatever lighting, heated grips, seat... en suite shower & closet you wish. The Alton only gives 100W which is not ...

Re: '58 SQ4 REBUILD

Hi Stewart - if you're not against sane upgrades; - strongly suggest an Iron Horse alternator - 12v 300W - then you can see, be seen & fit heated grips, an en suite closet & whatever takes your fancy... recommend you do NOT use cheaper alternatives to the Iron Horse device... Have Kirby Rowb...

Re: help sq 4 wont run

Hi Kevin - IMHO & experience; - the Amal main jet as supplied by Drags is way too small. I use a 220 - exhaust is not sooting & plugs come out chocolate... I run 12v via Iron Horse alternator, Boyer Bransden ignition with Kirby Rowbotham modified distributor such mods may contribute to the d...
