Fazer 600 with pod filters

[ChristoT]

Evening all!!

After a chat with Deefer, an interesting point was brought up: apparently, the FZS600 carbs do not like having K&N pod filters fitted, and the only place that has succeeded in getting one to run smoothly isn't giving up the secret. However, this is a planned bit for my build. So, has anyone here managed to fit K&N pod filters to the carbs, keeping the bike running smoothly, and more importantly: HOW DID YOU DO IT?!?

Just thought I'd throw the question up here, see what people make of it!

Evening? Morning more like!


I'm going to fit pods too. My guess is that not many have actually fitted pods to the Fazer and of those that have, how many have got it on a dyno to sort it out properly? Whilst I have no real experience, other than the pod filters on my ZRX (which work brilliantly), I don't see why they can't work well. On the ZRX the important thing to do was to make sure that two rubber tubes that attach to the carbs had their open ends well out of the air flow and sitting in still air. If they weren't then this could cause running problems.


The only information I found on line (probably from this site somewhere) was the following post:


hi just in case anyone is interested. pod filters ( cone filters) on a fazer 600 98 model caused running lean when accelerating on my bike. this fixed it.


change the jets from 115s to 125s on carb 1 and 4. and 127.5s on carb 2 and 3.also raise all four needles to the fourth groove down. problem gone.


sygma racing helped me , they are superb but very slightly expensive ( but your paying for there expertise).

Once I've got my rear end finished and the bike rolling again, I'll be moving on to the exhaust system and the carbs. So probably a couple of months down the line yet.

You could try calling the guy at Burra Motor Repairs in the Shetland Islands as he built one with pods. I spoke to him about the speedo sensor issue and he didn't have a problem with his non OE speedo: http://www.bikepics.com/members/burra/


Also try Dog London as they fitted pods too: http://streetfighterbikes.blogspot.com/2007/12/dog-london-fazer-6.html There is an email address for them at the bottom of their page.


Let us know how you get on.

Yep, Deefer said Dog London were the only ones he knew of who had done it successfully.

Some interesting stuff there though, thanks!

thanks for that Ruby, I havent been keeping tabs on the 600 side enough. I will add it to my big book of FZS stuff and try it sometime 

[Ruby Racing]

My pleasure. I'll be trying it myself in a couple of months. So I'll report back once I've messed things up!

Whats a pod filter compared to a normal k and n filter, if there is one?

You remove the airbox and have individual cone shaped air filters for each carb inlet.

Ah, thank you.

[Inertia_v1]

An old post but has anyone had any luck with this since then. I'm wanting to try this myself?

Regards

[Ruby Racing]

Still a work in progress for me.

[justanothernoob]

any progress with this? I'd be keen to give this a go too. Looks mint. But want to be sure the bike still runs smoothly.

I have a question for anyone who has run pods.

Describe what you mean by not running smoothly?

I ran pods on my old kat and had a engine tuner set them up, they were fine 99 percent of the time but if I cracked the throttle wide open under certain conditions it would hesitate slightly while the slides sorted themselves out. Speaking to the tuner he suggested I rolled the gas on rather that go straight to full throttle and tbh a little practice I was able to keep it just the right side of bogging down without any loss in acceleration

I hope this is the answer as I'm going for bell mouths so could really be asking for trouble if not.

But that's not really good enough is it?
You had them properly tuned yet were still prone to bogging down if you dared to give it a bit of welly, that alone is a good enough reason for me to not bother.

If I'm right in saying that CV carb slides hight are governed by throttle position, load and rpm then wacking the throttle wide open doesn't produce any more power than rolling it on. Had a ride on a flat slided G model GSXR and it would bog down if you  turned the taps on to fast simply because it couldn't deal with the amount of gas you rammed into it's cylinders

If as I suggested that part (or all) of the problem is caused by throttle control a rider would soon learn how to operate it without the dreaded hesitation

Guess the only way I'm going to find out is ride the thing and see what happens, not like thats going to happen any time soon.

I have got no further with my project bike for quite some time. But initial tests gave me a slight hesitation/fluffy spot in the mid revs. Still working on it.


With CV carbs you can open the throttle as fast as you like and there shouldn't be any problems as that's the whole point of them. The raising of the throttle slide is ultimately controlled by the vacuum in the carbs, not your right hand, and as such lifts the slides as fast as is possible. This is all tied in to the airbox shape and size and the manufacturers spend a lot of time getting it right. By fitting pod filters you effectively screw everything up! For my project bike I'm actually considering making an air box to fit in with my build aesthetics, however nothing decided on which way to go.


As I mentioned my ZRX runs fantastic on pod filters, but I fitted a jet kit developed by Ivan after running loads of dyno runs to get the best results.

So you basically need some very good resources, time, patience and a lot of constructive effort just so "they look good", which they undoubtedly do.
I'll stick with me K&N.
