stuttering fzs 600

[red98]

I balanced the carbs on mine this afternoon. While hooking up the vacuum gauges to the take-off points on the inlet manifolds I found the little rubber caps had perished quite badly:

I don't think they'd quite gone all the way through, the one I tried sucking on was OK anyway... I didn't test the others 'cos I didn't like the taste.
As a precaution I smeared some silicone sealant into the cracks.
With all the dismantling and checking you've been doing I don't suppose that sort of thing would have missed your notice, but thought I'd mention it anyway as a possible cause of a weak mixture.

well spotted fazerider [size=78%]......a split like that would indeed affect the mixture big time,mine are ok,but will double check to make sure ,just need to backtrack a bit now and see what i find[/size]   thanks for your input matey,did you notice the difference now your carbs are all pulling together
