cb900f carbs

Discussion in 'Technical and Troubleshooting Torque' started by wizud, Jan 25, 2010.

  1. I am having issues with my 79 cb900. It runs at 985cc with a very open exhaust and I am in need of advice re jetting. All is good until about 7000 rpm and then she starts to suffer from starvation. Any suggestions?

  2. Those CB9s had very fussy CV carbs. If you can't get it onto a rolling road, it'll be a case of trial and error.... Start a couple of jet sizes up from OE and take it from there.
