Working on a Vespa TS

I am currently helping my dad's friend sort out his Vespa TS to get it back on the road for the Jersey Scooter Rally in October. The TS which is a Vespa Rally body was produced between 1975 and 1978 with over 28,000 units made. The scooter has been having problems with its front wheel, back brake light not working, a fault with the headlight and possible jetting issues. It has not been used in a while so things like this are bound to happen. I'm looking forward to getting it running right, it's been a pleasure to work on. Here are some pictures.
