Some odd pics i didn't post

Bryanj:
500K3 was a European only model, was a 550 bottom end with 500 barrels and different bits in the carbs, only ever seen one in UK and that had been mis registered by DVLA as a tax exempt 1972 bike( don't tell anybody!!) Internals vary between 500 and 550 on forks but if you just undo the allen screw that holds the sliders on and leave all the internals in the legs, swopping complete, there is not usually a problem, until you forget what you did!!

 Interesting about the 500K3...never heard of that bike.

  Whats weird is that the only needles that seem to work on my bike are E2350F yet all the carbs I have except the ones off that 78 K3 UK bike have E2349F. I have measured the needles and they only differ for the top 25% the rest of the needle to the tip is identical. The 50's are slightly bigger dia than the 49's at the top making them leaner at initial pick up and low revs.

 I'm fairly sure that the other 2 sets of carbs I have are from F models and both have E2349F richer needles, maybe the 4-1 required a richer needle.

 Finished the bike off completely yesterday, rear footpegs, seat adaptor plate for catch - god knows what the seat is off, but it fitted perfect execpt catch and is like new underneath so I dont care - catch now works a treat.

Show us the pattern on the top of the seat - that'll indicate which model it came from.

I found out what it is now....I reread the ebay ad..doh..!!....'its a K0 seat, the one with the latch' it says..'not the plunger'.
  Well i didn't know they were any different all i was bothered about was a very good base with an half decent cover for less than the DS fibreglass shite that dont fit at all...result. Didn't read the ad that closely..it said cb500 four and I thought that'll do for me and pressed buy it now as quick as i could.

  I've made a neat adaptor plate out of 10mm ally to fit my plunger and its about the best fit seat I've seen. The pics dont do it justice, theres not a gap all round it and its totally original.
