Does anybody know if there is a dynajet kit available for the Z400?
Just a replacement for the unadjustable needle would be nice.

Also, does anybody know what the output of the stator is??? nothing mentioned in the owners manual.

 

yes there is a dynajet kit available, but they won't sell you the needle alone.

I used two no. 4 washers to adjust my needle.

I wouldn't waste my money on a dynajet kit unless you absolutely have to have the most HP.

 

Corpsi,
Thanks for the info. I usually don't use the dynajet kit but I figured it would be worth it this time to get the needle. Speaking of the needle, is there enough room to put the washers on? I figured that the needle retainer would not lock into place if I made that area thicker as adding washers would do. Did you have a problem pushing the needle retainer back into place with extra washers?

I took the filter cover off, added a WB E-series pipe and now its major lean. I'm thinking a 140 main and raise the needle 2-3 washers or clip positions.

 

JSsDS, I would try 2 number 4 washers and a 152.5 main with your setup.

 

Yep, there is plenty of room for the two No. 4 washers. Remember, adding the washers is equivalent to moving the clip down on an adjustable needle. I had no problems putting it back together. This is my first experience with a carb, so I'm not some pro who has done this before. Everything I have done, everyone can do.

Ack, zookyridr is telling you my set up. ( [img]i/expressions/face-icon-small-tongue.gif[/img] to zookyridr)
If you're going a Unifilter or K&N, you'll definitely need a 152.5
A 140 will be WAAAAAY lean.

 

You just saved me a s**t load of work and trips to the bike shop. I never would have guessed that I needed to go that high on the main. I'm thinkin this thing is gunna rip without all the restrictions...jetted right that is.
Thanks to you both for the info.

 

ROFLMAO!!!

 

Wanna contribute to the "corpsie is a dumbwit and accidently bought another 145 main jet when he already had one in there" fund?

 

No, I need to save my money so I can contribute to the "JSsDS overjetted KFX400 needs to go down to a 145 main jet fund". Care to contribute?[img]i/expressions/face-icon-small-frown.gif[/img]

 

I have a 145 main jet if you want to buy it. I can send it to you and you can mail me the $$ when you receive it (if you promise to pay me)
