Teds new project a CB500 K1 mostly version 0.5 circa 1972.
McCabe-Thiele (Ted):
Petrol tank now in place - not happy with the effort/wiggle needed to release tank cap from the catch so some fine tunning needed. Culprit seems to be paint on the tank cap & catch brackets. Improved things by greasing the catch itself and the bar/pin on the cap.
Ended up routing the two inline filters under the carbs as suggested by a member here - looks okay - quite a tidy solution plus accessible.
Having a few days away at the weekend so no bike work until next week - it's pretty much done now just needs seat, badges fitting to tank & side panels plus some safety checks with my torque wrench. I'm also going to ensure all my earth connections to the frame are good with powder coating removed so will be using my AVO meter to check for any voltage drops.
A shake down ride looks on the cards in the next couple of weeks provided domestic duties do not slow me down. I will post a photo when I have done the above.
Mike_Berkshire:
Exciting news Ted! I would be interested to know how you go about testing the earth points as I am going to need to do the same at some point in the future. With the burnt out earth wiring in the loom I have it’s clear that even before I had the frame powder coated my bike had a problem.
McCabe-Thiele (Ted):
My simplistic method might have no scientific basis, I will measure the voltage between the battery terminals then take measurements with the live at the battery then see if there is any voltage reduction when I earth the volt meter at various points including the end of the earth strap, at the coil earth, engine casing, headlamp shell earth points. Ideally I should be looking at any changes due to resistance in the earth circuit so might be more meaningful under load.
McCabe-Thiele (Ted):
For safety reasons my brother helped me get the bike off the center stand as it was effectively stuck on the bike ramp - the stand just slides along the ramp so it needed some effort to hold the centre stand firm on the base as I sat astride to bump it off the stand so as to speak. I need to work out a way to do this unassisted.
Mainly due to lack of space the 400 was then ridden onto the bike ramp and up on the center stand - with a tie down strap at the front through the steering gap.
A little bit of tweaking was needed as number two cylinder was a tad cooler - now running nicely on all four cylinders sufficiently well enough for a shake down run. Run today postponed due to cool weather, quite windy & a few spots of rain at lunchtime.

That's lookin very swish Ted. Credit to all your hard work.
