Replacing the Gear Change Spring on Swinging Arm BSA A10

Working on the A10...

Being pressed back into action for the first time in years, you sort of expect a few issues. The only thing that went wrong was the gear change return spring snapping, but did it leave me stranded? Not at all, shoot back home, take off the cover and order a new one. It was there the next day! 

So, without further ado... The outer cover comes off easily with four nuts to remove and three screws. The kickstart and gear change can stay attached at this stage and makes it easier to remove the cover. Also, the outer cover can be removed without affecting the gear indexing so makes this a very easy job.

With cover removed, you can see the offending item sticking out behind the gear change mechanism. The split pin, visible here, can stay in place, just remove the tiny circlip from the outer side of the cover and the whole unit will slide out from this side, revealing the spring.

Making my favourite Brit twins even better!
Anyone involved with classic BSA's will have heard about SRM engineering.  Originally formed by Steve McFarlane, SRM was famous for Steve's oil end-feed crank conversions - and still is.  My own BSA A10 had the conversion, along with other cool modifications, when they were still in Cardiff.  


Present day - and while SRM is now in Aberystwyth - Steve remained in Cardiff restoring and repairing classic and modern bikes in his new workshop in Brunswick street.  


Trust me - this guy can fix anything!  The standard of his work is second to none and, where I normally can't stand anyone else touching my bikes, I'm more than happy to let Steve work his magic when I need a rebore, crank regrind etc. (He once repaired a huge hole in the chaincase of my Norton Jubilee and the finish was stunning!)


So what's new?  
Well his latest creation is going to help a lot of classic riders enjoy their bikes well into old age.  A starter motor conversion for your BSA A10, A7, B31, B33 and Gold Star swinging arm models. Starter conversion


This kit is designed to be invisible when fitted - much like the crank feed conversion - and the quality superb.  Steve wouldn't fit it unless it was just right.  Take a look at the pics.
