Jetting for a z400?

[Hondaracing819]

I have an 05 Z and i put on a yoshimura rs-3 slip on. I put it on and tried running it with the stock main jet but it wont idle. It will run for a little but i have to give it gas...

I bought a dynojet kit for it and i dont know what size i should put in

can someone help me out

I WISH I COULD FIND MY BOX AND I COULD TELL WHICH ONE I HAVE IN. TRY TAKING YOUR AIR LID OFF, IF IT RUNS FINE THEN DO WHAT I DID AND DRILL HOLES IN THE LID SO IT KEEEPS THE MUD OUT. IF NOT MAYBE START WITH THE MIDDDLE ONE AND TRY ONE AT A TIME. JETTING DOES SUCK BUT ITS NICE WHEN ITS RIGHT. GOOD LUCK

MAYBE YOU CAN CALL DYNO JET AND THEY WILL TELL YOU WHERE TO START.

what size does dynojet say for you mods.

get a dynojet jet kit and run stage one. air box lid on. you may still have problems but only when stopping when u hold in the clutch and brake you will have to give it some gas to keep it running but will run better.
