at 12.5:1 don't you need to run some race gas in there?

I was just told about the intake boot from the carb to the cylinder. It seems the one from the z is smaller than the one from the DRZ (dirtbike). They bolt right up and I think the guy at the dealer said it was about 30.00.
It really opens the intake to allow more air flow. I will look into this deeper.

seems like all the parts from the dirtbike engine are better, just buy one of them :roll:

ill will be posting some pics of the best air box mod your air box which should increase air flow by at least 30%

air box lid

I bought a stock lid for my 300ex, drilled and installed some of those 1" vents and WOW what a difference!!! I plan to do the same with the NEW Z. Just remember to put the solid one one if you think your gonna take the Z swimming! 8O

 

[Zeeper]

Bio - I just did the same thing to my Z.. I Added a Uni and removed the snorkle. Put 5 of those 1" vented holes in the top of the lid, and I think air flow really increased. I'm having to run a 152.5 main and I'm going up to the 155... Removing the snorkle will open up alot by itself.. That thing is really restrictive..

 

[bigorangeZ]

I'm planning on picking up a lid this w-end to drill out. What is the stock jetting??

I'm still breaking in the "New Baby", waiting to get a pipe, filter, and new jetting!

 

[yamamonster]

stock jetting

main jet 130
pilot jet 22.5

 

[yamamonster]

jetting?

just installed bills pipe full system,they recomend changing main jet to 170 and pilot to 27.5. thats it should i do anything else? (drill lid,remove snorkel?)

 

[ltzrunner]

I've read a couple things about the 170 jetting....TOOO RICHHH!! And could someone please educate me...I have the Z400 service manual, but what the heck is the snorkel? Anyway, I highly recommend the manual to anyone wishing to do their own work!!

 

[bigorangeZ]

Thanks ya-monster! How do you like Bill's pipe?
I am waiting for next months DW, they are supposed to have the full pipe test on a Z with all the makes and models.

 

[yamamonster]

reply big o

LOVE IT! sounds great runs good not sure about jetting. im going to follow their recomendations and see if it runs any different. good pipe for the money. wish i could have tried one of each for free!

cutting lid

found a filter to go on top of airbox lid so you can cut the holes and have extra filtration. i think it was about 60.00

 

[Buzz102186]
