The next job was to the state the engine was in it had 50,000 on the clock,

I had ridden it home and from a small misfire it had ok.So I stripped it

The fork legs were so that the seals had been and were leaking badly were

restored them to as as good as new.Although this to be quite expensive but it was

at least the price of new legs.The next to tackle was the state of the bearings in

these all proved to be up to spec,on the gearbox bearings were

to show some wear.Surprisingly were not as expensive as I would expected.In total the

this had turned into an to restore this bike to original state as it

left the shop in 1979.

The I have obtained a lot of my parts are Robinsons of Canterbury they

a good stock of parts for the Suzuki’s, but when I ordered the for the tank

the answer was that are no longer available not even the factory,undetered

I thought I’ll get to make them.Everybody in graphics can them providing you have

Progressing towards

Almost ready to put in the engine

was June 2000 yes its in the lounge.

had the bright idea of having an built all that dust! it the bikes

in the lounge for the duration was done for over five what with the

extention,holidays,and of cash things slowed were on the move again now and the

loom is on and working with a new in place the next job will be to fit the

months later.

The exhausts been fitted and the battery but it was reluctent to start,it turned out the earth on the Boyer Bransden ignition was making a poor with that fixed it ran but very lumpy and missing,I was not very happy with because it was timed on the correct to mark for it to run. this hopefully be sorted when the is ironed out and the carburation has been set up it will run a bit more like it

uneven running continued,time to go to the drawing board and check from the begining. After through again all the connection had resoldered with new connections but checked anyway,then what’s the pulse generator leads are and white and up the top by the frame the black into the white and the whites is black whoooops. lets try the other way.


The intermitent misfiring continued, the the only compnenent part of the system being the Boyer-Bransden box and the wiring the next thing to would be the box its self. This was by a visit to their place Detling Nr Maidstone in Kent, tested the box by setting it up on their rig, at the time the chap who it said that it was about years old .At first it worked O.K I thought) and after about thirty seconds it started to reasonable sum of around forty inc V.A.T purchased me a new one. installed and a timing light an electronic rev counter (borrowed a work colleague) it was a different it was smooth and it started as soon as the pushed.

The petrol tap was a mess the diaphragm was jammed solid. all had to be dismantled and cleaned and refitted to the ,new tank badges bought and fitted, the seat was I have been riding the for most of the summer (fine only of course) and have it very much, although a Bandit for day to day transport for work you can feel the twenty year gap in the where the brakes and suspension are has been a bit lack lustre and was o.k but the battery,although new was sounding abit turned out that the regulator/rectifier was with this now replaced a difference the afore mentioned year has shortened considerably!!

The only remaining things to do are to the tank resprayed because of a in the front brake master which all blew back the tank whilst riding it. I new I have fitted a repair kit I restored it. The adhesive decals can be applied to the tank side and rear light cover.I enjoyed this restoration,the one that I have enjoyed the is the nice people I have met the way see below.

The recently added is with all the decals fitted three years to get round to it, looks good although it does dry miles,except when the forecast is wrong.


This is the 1974 L Mentioned earlier now finished 3 years of fun well sometimes

This project was all my own work for the frame which was stove by the guy that did the GS for me. I personally like the enamel finish it looks glass tube,but be wary it chip if you drop a spanner on reason for this restoration is my has decided that she would to learn to ride so this she does her CBT.
