Cabling and wiring

I have no photos of this phase. I did take some but the card for my digi camera gave up the ghost so they are lost. No problem, as there really isn't much to see. I pretty much followed the routing guides in Sticky's Lambretta manual, and I used strong and long cable ties to mock it all up, then checked everything was working (start up, test lights, brakes etc.) before fitting the aluminium ties.

I did make a rather annoying mistake when fitting the bodywork back on though. I stretched the throttle cable out of place with the legshields, and when I discovered this rather than remove the legshields again (which were a pain to fit as they are a bit mis-shapen in some places) I had to fiddle with the cable in situ beneath the bike.

Fitting the hydraulic disc brake

Fitting the hub was fairly self-explanatory, and the one problem I did have (front wheel not being central in the forks) I posted about previously, and I rectified it by straightening out some wear on one of the fork links. It is worth noting however that these hubs (mine's a SPAQ/Sterling jobby) don't require a nut between the link and the large plate on the right hand side. The hubs don't come with them, but at a recent parts fair I saw some of these hubs with nuts fitted - I guess the stall owner thought they were missing and fitted them!

Here's a pic of the assembly in place:



To connect it all I discarded the rather bulky rubber hose that came with the unit and bought a new slimmer Goodridge braided stainless steel one from http://www.busters-accessories.co.uk/. This is what I got:

Buildaline Adaptor Banjo 90deg 3/8 Jic Male 5.99 1 5.99
Buildaline Adaptor Banjo 45deg 3/8 Jic Male 5.99 1 5.99
S/B Buildaline Hose 1100mm Clear


The 90 degree banjo enabled me to avoid having any exposed hose at the top of the bike. I simply used a round file to create a hole in the top if the headset for the banjo and the small front brake wire to feed through. Here's the end result, a lot neater than any others I've seen:



And here's an internal shot, showing how it all worked out:


Here you can also just see a replacement white earth wire that I fitted from the headlight to the mounting point of the throttle guide. This provides a more reliable earth than the headlight rim as is standard. The loom comes in on the right on my bike, as I simply couldn't find the room on the left!
