legshields and carburettor

The legshields on this bike incorporate a small cover for the carb. The air slide pin is extended to pass through this and ends in a (degraded) bakelite knob. Sadly this fell apart when I removed the cover but I'll keep the pieces. This pin isnt listed in current parts catalogues.


Legshields are held on at 3 points... under the tank... 19mm nuts each side

Very short, they just pass through the tank into the hex rubber mount.

Tilt forward and lift off the tank (fuel hose broken on mine) revealing the hex mount system

The rubber blocks unscrew by hand

I reassembled it inc the small bolts for storage.
It's also held at the front by a cross brace. This is retained by 2 screws with cup washers below the louvres.

Remove these screws...
...and the cross brace comes out

The legshields are now held by 2 10mm nuts onto a pass through stud at the lower rear. In my case one nut came off but the other unscrewed the entire stud so this will need cleaning and lubrication before refitting.

This allows the carb to be seen. The cable enters through a canted guide tube at the top. I cant find this type of carb top currently listed. The guide is screwed into the carb top but not tightly, it has the ability to move and so swivels easily but I don't know how air leaks are prevented. The cable outer ends in a ferrule which fits into the guide tube; the cable-to-guide tube joint is sealed with a rubber boot. Cable adjustment on this model is at the twistgrip end.

I dismantled and cleaned the carb pretty much as previous described in my other blog. I reassembled installing a new throttle cable and was pleased to see the twistgrip works well.

Currently I'm cleaning the tank which I'll remount with the renovated tap in order to ride the bike and check gearbox function which I can't really do unless under load.

Not refitting showed that the new mounting block was too high to allow the tank to fit (block hadn't been present when I dismantled the bike). I has to trim it to allow the tank to fit.

Speedometer fix (replace magnet) and headlamp wiring

Image
My speedo looked OK but didn't deflect when riding. Further when  I connected the new cable it just rotated with a knocking sound. I therefore removed it. I found that if I pushed just the inner cable in really home then I could get a deflection when that was rotated by hand. However it was inefficient (slipping cable?) and didn't return to zero unless shaken or tapped... it seemed to stick at around the 5mph mark. The speedo is not made to come apart... its held by a metal cover plate on the rear which is clipped under the plastic rim on all 4 sides. It might "unpop" but that seemed very likely to break the plastic lugs on the case.  Opted to make a controlled cut. There are 2 slot  recesses (one each side) towards the flat edge of the speedo. These are use by the wire clip that holds the speedo in place. I opted to use a hacksaw to cut across the flat edge lose to the bottom but within the depth of these slots to detac...

fuel tap

There was no flow at all through the fuel tap. It was easily removed although it does have a peculiar mounting nut. The screws onto the yank in an anticlockwise direction whilst the tap body screws into the other side in a clockwise direction. There was no flow even after sonicating so I was forced to dismantle it... gripping it in a vice. I coukd then use a pair of internal circlip pliers (90 deg) to locate in the slots and unscrew the face plate under the tap lever. The faceplate lifted off revealing thesegmented washer that determines the tap lever position beneath. There was also the remnant of a red sealing ring but I couldn't tell what it was made of and it wasn't clear if it should go above or below the segmented washer. These components lifted out The washer was removed. The gasket plate visible beneath was also clogged and appeared damaged. This is a cork plate although most taps I've worked with are rubber. I'll ...
