Title: Z400 Sputtering Post by: z400hick85 on January 06, 2007, 11:22:41 PM I've got an 04 Z400 and it recently sat for a while (2 months or so) and was rarely ran. Well, I drained the gas out of it and put some new gas in it. It runs funny now.. I was in 5th gear topped out and it started stuttering and spitting. Think this is a carb issue and it needs to be cleaned out?

Yes, most likely your carb has varnish in it, taking the bowl off and cleaning out the jets, needle and seat and it should solve your problem. (fuel starts to vanish after about 2 weeks without some sort of stabilizer) btw, stabil usually keeps that from happening Title: Re: Z400 Sputtering Post by: 06 BaNsHeE on January 10, 2007, 07:25:47 PM Take out your carbs and clean them.Take em apart and clean everything.
