Seat update

Installed Sabelt cushions to back and base. Completes the look a is comfortable for longer trips.

smiths speedo cable

Symptom: Smiths speedo was bouncing 40kph.

Fix #1: removed the speedo cable and inspected the speedo. Attached a drill and ran it in reverse with a consistent smooth indicator. The speedo operates correctly.

Crimped speedo end of cable was damaged and cable did not sit snuggly. Installed a diy crimp and soldered the end of the cable.

Results: were much better with 10kmh bounce but the repair did not last. After a few weeks the bounce started tonincrease again. After removing cable again the fitting was loose and the soldered end was worn.

Repair #2: sent the cable to vintage British bikes in Red Deer Alberta. The cable was shortend 1/2 inch and a new crimped end was installed.

After reinstall and test drive the cable and speedo are as good as new.

Floatless Fuel Tank Sending Unit

The seal at the top of the fuel tank for the Sending unit started to leak. The garage was filling with gas fumes and the float-style sender was bouncing when driving. The overall accuracy of the old float style was also in question.

I removed the old sender and replaced it with a new Tanks Inc 9" floatless design. The Sender is Smiths Gauges standard 10-180 Ohms. If I ever decide to replace the Lamco Fuel Guage with a Smiths it will be compatible. The top and bottom of the tube have a 2mm hole to allow fuel to fill the tube. The entire tube contains the fuel so that movement when driving is kept to a minimum.

The sender is connected to the LamCo Adjustable fuel gauge.

On each side of the Light bulb socket is an adjuster for the Ohms for full-tank and empty-tank. Full was adjusted. After driving I will have to reset the empty level.

Adjustability was not sufficient. Purchased smiths 10-90 ohm fuel guage. With the 1" space to bottom of the tank I should have a 3 to 5 liter reserve. Currently at 160km and 1/4 tank left. Will refuel at indicated empty. The recalibrate reserve capacity.

mikuni phh44 carbs

Step 1 was to balance the carbs, check plugs and tune.

Symptom was overly rich on cylinder 3. After close inspection I was able to move the jet block 0.5mm. The entire jet block is loose. It was time to order parts. Best afr I could get was 12.7 idle and running and 10.5 on WOT.

Starting point for jets was 165 main and 210 air with 60 pilot.

Tuning made it drivable but was still too rich on cyl 3.

Changed air correction to 220 and main to 160 and pilot to 57.5. Minor improvements for afr. Better performance but still too rich on #3.

Changed jets to 155 main, 220 air and 57.5 pilot. Still too rich on #3. So it's time to check the jet block and orings.

Rebuilt carb with cylinder 3. The figure 8 o-ring was not sealing under the jet block. This is accessed by removing the accelerator pump and removing the jet block retaining screw.

Cleaned the carbs and reinstalled with new o-rings.

Back to step 1 and balanced carbs.with syncronizer.

Set pilots at 1 turn and restarted. The afr jumped to 14.5 to 15.0 at idle and blips to 12.5.

Opened up the pilots and it currently sits a 2 turns. Will have to set after its on the road in spring . Much better response 👌
