Hi Simon; - I'm in the process of moving house - (to Walton on the Naze) - at present I'm ~90 miles away from my Square & other bikes as all have already been moved into storage. I seem to recall I used an extended bolt on one of the lower primary chain case cover fixings to fit an eccentric adj...

Re: Calling All Mk1 Owners

Hi Simon; - I confirm that on a Mk1 i.e. all ally engine (no iron "Mk1's" were ever made but they are often mis-named as such)... The pipe with the largest offset should be fitted to the LEFT hand side of the machine. When fitting any OEM pipes (or for that matter true originals if you can...

Hi Huw - please can we know model and year for the machine you are so concerned about? - and what do you use it for? I'm somewhat bemused by the exceedingly high pressures being suggested... An alternative to a security bolt or some form of rim "glue" is to drill into the sides of the rim ...

Hi there - A "Security bolt" may be fitted - this only prevents the tire rotating within the rim-well and thus (theoretically) prevents movement of the inner tube which may rip the valve out. They are normally used by motocross & trials riders who require low inflation pressures to ach...

Re: Classic vehicle tax

Now that in the UK any motor vehicle pre 1960 is classified as an historic vehicle - it gets free road tax and no longer requires an MOT certificate. Sounds great - but can anyone clarify the insurance situation because I well suspect that insurance companies may refuse to pay out with the excuse th...

Hi "admin" - a possible lead for your brake part may be http://www.ajsmotorcycles.co.uk/ - a few years back this company supplied me with all the necessary fittings to cable up a 4LS on my Square - by their website it would seem they have changed their main stock lines and direction but th...

Hi Brenton - thanks for the suggestions. Idle is set by stop screw - using cable length to do such may produce some interesting(?) behavior when maneuvering at low speeds... Pilot galleries (there is no jet as such) cleaned by wire & airline. Problem solved by resetting needle height clip from c...

Hey Simon - that seems a good idea - I've only a rear stand on my '49 Sq but have often considered a decent & SAFE side stand would be advantageous. I sold my other Mk1 Sq ('51) which had the std side-stand - as you imply ONLY safe on flat & level concrete...
