Zx6r carbs on 1300 ford crossflow
Hi I have just fitted zx6r carbs to my crossflow .an just fired the engine up this morning but runs very rough the only thing i have done screwed the
idle jets in an out 2/half turns this has helped still to balance them up as well . Has anyone ever done this on a crossflow it was just to some idea
of main jets sizes any information on this would be very welcome cause I haven't a clue . Thanks

Bike carbs
Cheers stu seems a lot of you guys are running 1.6 jet sizes or anything from 1.3 to 1.7 /. 1.6 being the norm . The jets that are in just know
outside ones are 1.4 the two insides are 1.5. So I was going to start there. Do you know how to check for lean fuel is it a case of checking the plug
colour. Thanks for the reply.

The only safe way is to get it set up on a rolling road
I would start with 1.5 jets and work up
After drilling the jets get the carbs balanced and go from there

If its running rough the carbs probably need balancing. When mine are out of balance my zetec runs really rough, hunting and barking...

As Jacko said a rolling road is best, however mine were done at home using a wideband AFR meter.

You are going to struggle tuning an engine, with a set of motorbike carbs, without any diagnostics available to you at all! There is no default jet
size, needle position or idle mixture for any given engine. Everyone has a different air filter, exhaust and manifolds. I had to put a wideband on
my car to get it running and then drive it, and tune it as I went.
