I have a Z400 dose anyone think a 39mm fcr will work on my z400 I have both hot cams and a 13:5.1 piston and I'm not sure if I want to go up on the bore size any time soon. I was also thinking of just getting a edelbrock. I was told with out the big bore the bike would fall on its face mid and top end that is with the fcr also what about a vortex cdi.

 

you should have no problem I have a 41 mil on mine
you'll have to rejet it. stay away from edelbrock heard to many bad things about them
not sure about the cdi

 

Yep it will work great...keep an eye out because YFZ owners like to get rid of their FCR39's for very cheap...I've seen one go for $195!! The Vortex is also a great mod. There are 10 adjustable timings for all type of situations...kinda expensive, but well worth the $$$ IMO.

 

Yea I think it will work great on 440 but like I said I have a stock bore I just not sure if it will perform right.

 

195 for a yfz-450 is what they cost brand new. Its when you get the carbs off the dirt bikes is when it gets exspensive.

 

I know plenty of stock bore stock stroke Z's that have FCR 39's and wouldn't trade them for anything...

 

So If I did get a 30mm fcr from a yfz 450 what all would I need to do to make it fit on my quad? like thumb throttle cable? or what? is a yfz fcr compatible with the z400? whata re the pros and cons of using that carb?

 

a 30 mm will be to small for the Z. the 03/04 models came with a 36mm carb on it
I run a 41mm fcr and it has way more response then the stock one but I had lots of motor work done too

 

I just put a 39mm FCR and a Dyna CDI on my quad. It gave as much if not more of a gain then the cams & base gasket.
Very good improvement IMO.

 

what exact carb should I get for my 04' z400 with both hot cams drz-e base gasket springs, dyna cdi box Full Lrd exhaust no lid KnN intake????? I have no idea whats the best deal or say best bang for my buck carb for the set up im running? what price will I be looking at? and where should I look? and if you know of any for sale now can you help me out?
