air box, to equalize pressures. Engine ran rough as a rough thing, removed tubing and it had fuel in it
, it looks like fuel was being sucked into
carb intakes.
What have people done with theirs? I had a small filter on mine, but thought it would be better if the hose was connected to the
air box, to equalize pressures. Engine ran rough as a rough thing, removed tubing and it had fuel in it , it looks like fuel was being sucked into
carb intakes.
I use a ZX9 engine in my autograss car, not exactly the same thing as your situation but along the same lines. I found that the carb vent really has
to be inside the airbox to get the top end power from the engine.
This video on youtube https://www.youtube.com/watch?v=KtISwbsv-yc brought this fix to my attention where when people convert the zx9 bike to a
streetfighter, they loose some of the ram air pipes or something, putting the carb vent into the airbox pointing into the direction of air flow fixed
my problems.
I also had fuel coming out the carb vents, I bought a carb rebuild kit for each carb about £10 each and this seemed to fix my problems with hard
rubber on the float valves.

If its the ones on the top they just need to go to air. I just swung them round, pointing down and ran 2 bits of tube level with the bottom of the
carbs.
Just to add, I found out the hard way, thought the carbs were blocked, spitting and back firing so cleaned then with thinners.. DOH! Back to ebay for
another set....

I thought that since the ZX9 is a ram air engine that with the increased airbox pressure at speed the carb pressure reference should also come from the same point. My engine saw a considerable jump in performance when the carb pressure refrance was put into the airbox. Much more lively in te higher revs, happy to go way beyond 12000rpm
