Okay

Boiling away

The floats appear to leak,air bubbles coming from them,

As for the copy carb ,I was going to use it for spares,

And the body incase damage to the original,

I did buy a set for the CB200, they worked ok,

"But, no rush, a little later I shall be making carb broth,"

Aha, the gourmand method  ;D chuck a couple of eggs in to boil and save energy, is that Michelin Starred œufs ?  :D

Solder should be 180c melt, so safe in boiling water. But shows a compromised float though, and may need a re soldering before use.

A couple of hours pottering in the garage,

Carb almost sorted, float pivot released

Only issue now is new gaskets, oh,and one of vents is still blocked,

Possible sonic cleaning will sort that,

Replaced the oil feed pipe without having to remove the clutch cover,

On PDI,the steering damper was wrongly assembled, also the throttle cable was routed wrongly, both sorted,

When the bike runs, the charging light stays on, it has a combined dynamo/starter,the starter works ok,it has been suggested I check the brushes, and also the regulator

So been working on that

  the Chinese VM20 carb arrived,I odered it incase the original got damaged,

  it doesn't look to bad,obviously would need a mod for the choke,drill out an insert brass tube,

  I would be using the original jets and brass ware,

  useful safety net for £25 or so,

  I have had the original cleaned in a sonic bath,assembly to follow,
a few pics of the chinese carb,

 BTW,I notice they do replacement pertol tapes for the 500 etc,
