My Z seems to be running just a LITTLE bit rich, so the spark plug says.
Here is my setup:

K&N Filter
Airbox Lid Removed
Dynojet jet kit
160 main
White Bros. E-Series slip-on with all 12 discs

Any ideas how to get more air in? Or do I need to rejet?
The plug isnt completely black, but blacker than it should be.
Any help greatly appreciated!

 

is it performing good?

what kind of plug check was it? 1/4, 1/2, 3/4, WOT?

 

hmmm iam running a 165 dyno jet in mine and white bros power filter with two 2inch holes in lid 3 turns out on air screw. runs great..

 

If you want some more air flow , remove the little screen inside your carberator. It will let more air pass threw smoothly.

 

hey murdr i remove my little screen and it helped a lott pulls a lot harder now. i think i need a new cdi now lol.....

 

It performs EXCELLENT, but I am just concerned about it being rich.
Maybe I am being paranoid, but I just dont want to wreck anything.
I am an amateur at jetting, if you couldnt tell already.

nosliw-
I didnt perform an actual plug check, I just pulled the plug out
and looked at it. This is probably where I am screwing up.
What is the best way to actually check it??

 

I was told to run 1 size larger on the jetting
its better to be rich than to lean
and get the full pipe

 

put in a new plug
start 'er up
let it warm up by itself
let it idle there with NO throttle for 5 or so minutes
shut it off
check the plug

put in a new plug
start 'er up
if it's still warm then take it out and go for a while using only 3/8 to 1/2 throttle at the most
clutch it and hit the kill switch
come to a stop
check plug

put in a new plug
start 'er up
probably still warm so take it out and rip through the gears to the highest and hold it wide open for 8-10 seconds, then clutch it and hit the kill switch
come to a stop
check plug


^that's how i did it anyway

but if it's running a little bit rich, leave it. you'll run a little cooler and have the peace of mind that nothing's going to fry.
