Hello guys,

I have just finished renovating a 92 zxr400. Tried it today and think its running a bit lean on very low revs and idle. I am planning to turn the pilot screw in a half turn since i understand thats whats sets the idle and midrange mix. Am i on the right track here?

The pilot screw, a much loved subject here, turning it in leans, and you can blame Banner if it doesn't
I'm about to lean my idle a little, turning in by a quarter, even though general consensus suggests mine is already lean on idle, hangs a little, I'm going against this just to be awkward, and see if a rich idle causes the same issues.
To sum up turn yours out if you want to richen, probably.

Hahaha, awsome answer! Ok i will try turning it out and see what happens. If you have hanging revs it is more likely to be an airleak. I had that aswell but dissapered when i changed the inlet rubbers.

NO airleaks whatsoever.

Thanks for the help. Turned it a half turn out and now it is perfekt! So it defenetly richens by turning it out
