1979 cb650z uk model
« on: December 10, 2021, 05:22:14 AM »
Hello folks,could anyone tell me the clip position for the needle jet on a cb650z,1979 uk model. dont see it
in manual. The bike is being assembled back to standard. Main jets are 92 and the bike will have original
airbox/exhausts fitted. Its just that looking under the main jet/emulsion tubes,the needles look different heights.?
Can you help?

the needles on the 79 are not adjustable. only on the linkage when vacuum syncing.

The UK bikes may have had adjustable needles, only way to find out is to take them apart.

CMS is showing adjustable needles in their parts fiche.

If you join the UK Forum, there may be members more local to you that could possibly advise, especially as its a UK model and you're in UK.
