Why is my Z400 not starting!!!

My Z was starting up fine for about the first 15 hours.... then I took it on some trails and rode it pretty hard for about 6 hours. Everything was great till I tried to start it the next day. It took me like 15 min to get it started then when I did it stalled. I got it home cleaned it, checked the air filter and it was clean. I pulled the spark plug and brushed off the carbon. The plug was clean and the porcelin was still white and lookin brand new. The plug was dry. I am at a loss and they want $110 bucks to look at it at the shop. I figured a problem like this would be covered under the warranty.. but they say NOT. Anyways, anyone else having any issues getting this quad started? Could I have bad gas, or maybe 89 octane is not rich enough? If anyone can help I would so appreciate it, cause $110 bucks seems like a rip especially if it might be something simple... let me know

Re: Why is my Z400 not starting!!!

is it turning over? or nothing when you hit the starter....

from the sounds of it, its turning over but just not starting...if I were you just get a new plug all together, I dont think the octane in your gas will do it, if you have 89 that is good enough....

I would go to your local shop or dealer and have them order you a spark plug, the gap in the plug could be off to, how does it idle?? you might need to adj your idle screw...

have you changed the oil and oil filter? just do the thing with the plug, see if it works, I am sure it is just not getting very good spark

clean the carb and air filter. Next drain the gas and put some fresh stuff in. Also change the plug.

Perhaps it's out of gas? [img]images/graemlins/grin.gif[/img]

..... LOL (Just had to do it, but I'm just kidding with ya)

Does the Z400 have a vented gas cap? If so, try starting it with the cap off. Perhaps the tank is not getting any vent? Otherwise, check the fuel lines off the tank and into the carb. Most carbs have a bowl drain on the bottom of the fuel bowl. If it does, and you open it, does gas flow out? Finally, you may need to remove the carb and blow out the jets. It doesn't take much to clog them.

Some other things .... Is the air cleaner clean? Is it getting spark? Did you ride it through water? Perhaps you got the stator wet?

Good luck,

Tony P.

Your Z should be covered in the warranty and your suppose to send it back to the dealer after the first 2 gas tanks you go through so they can check the valves and all that good [bleep]. I sent mine in. Z400's rock
