thanks for that info much appreciated

yes i knew thank you is it ok to post engine and frame no on here?

yes i realise that it is not original  but it came that way all the plug ins  fit surely  this has been done before. I have just  looked at engine no ending 500E is the engine an f dont know year, excuse my ignorance.

Ah that may explain why it looked as though it had been hot wired. the replacement harness is the same as one fitted is there away round this everything on running gear, frame is cb 550f ?

Hi I am in the middle of re building a 550f2 ? 1977 usa import came with 500 k? engine fitted have removed engine stripped engine looks to be very good internally oa standard bore all in spec i have de glazed bores unbelievable condition.
wiring loom poor but have very good replacement,Is the wiring on 500 same as 550f?

correct silencer becoming rare item now[ rust out] good project

 I also use a soda blast gun on parts agree slow using a lot of media, but good   patience required and it does kill grass.
