DIY snorkel removal, AKA Poor Man stage 1 filter cover.
 

Hi:

I own a XT660Z since last saturday, it is time to start mods ;)

Snorkel Out.

A visit to the local plumbing store ended with a rubber than fits either a WC :tongue3: or a XT660Z filter cap.

Placed on the filter cap.

And installed on the bike.

I will remove the cover in a few days in order to check that it works as expected, but it looks GREAT!!!.

Excuse my English, I'm spanish.

have fun,

Nice cheap mod. Thanks for sharing.

I bloody like that!

So is this a BOG standard modification? :pottytrain5:

Barry.

Well did it seal well enough :119:

So far so good after 9000km :) ;)

have fun,

oooh I like that, I even have a bog seal in my attic...that's gonna be a cheap mod. Will I need to fiddle with CO settings or anything else do you know?

Excellent! I've just done my bathroom and have got a spare one of them!
Nice one.

Brilliant!!

Mine was 'Stanley Knifed' and is clearly a one way conversion..

This is the kind of mods I like. :thumbsup:

Has anyone priced up a new snorkel ?

I'm a 'reversable mod' kinda bloke, so I opted for the DNA option. It might be that purchasing a new snorkel and cutting it might be a more viable option if the price is right (come on down...... :icon_shaking:)



:017:

I'm tempted, will I need to do other fuel mods settings? CO or TPS?

I did adjust the CO and TPS, but a friend of mine didn't, both bikes run fine with OEM filter. If you use a DNA or K&N filter you need either the wonderful inespensive Kev mod or a powercommander, and you don't need to adjust CO or TPS

have fun,

Hi! I removed the snorkel too two days ago (sound has changed a lot for the better!).
I found it sufficient to remove the snorkel part from the ring and screw back in place the ring alone without an additional gasket, other folks here seem to have done the same as I did: do you find it important to add a rubber gasket as you did? If so, why? Biker seems to run fine without btw.

You only need to add an additional gasket if you completely remove the snorkel. If you cut it down (as I assume you have done) there is no need for another gasket as you will have retained the bottom part of the snorkel which forms the seal.

No, I haven't cut anything. I just separated the ring from the snorkel.

Here is the way I separated them:

Here you can see the ring on the right, separated from the snorkel:

And here the ring mounted back in:

Do I need a gasket of sort? And why? What shall it seal?

As you have it, the top of the air filter (the foam sealing ring) is exposed and not compressed against the airbox top ring. I should imagine the filter wobbles and can be moved about a bit? It won't be forming an airtight seal between the filtered and non-filtered sides of the airbox; you are likely to be getting unfiltered air into the engine around the circumference of top edge of the filter.

The top ring of the filter must be sealed tight where it meets the opening of the airbox.

Your choices are: (1) Make a gasket/seal out of a rubber toilet pan connector, or use a coil of petrol pipe or vacuum hose. (2) Cut the snorkel off at its base separating the circular sealing part, then refit the lower part in the airbox top ring. (3) Buy a DNA Stage 2 top cover.

A wobbly and poorly sealed filter will be bad for engine wear in the long term, and it may well cause fluctuating pressure changes in the airbox, which could in turn cause erratic weak running and give the ECU a hard time working out what's going on.

+ it will affect the A/F ratio with the loose filter causing the motor to run leaner than it should.

Great info folks, I thank you all! :icon_thumright:
That makes very much sense to me.

Being the MacGuyver junkie I am, I opted for a diy solution: I always enjoy a trip to the hardware store! :icon_mrgreen:

Here's what I bought, for less than 3 euros total:
- a carboy gasket
- a pipe connection gasket

The carboy gasket fits the original snorkel well indeed:

Also the pipe connection gasket, which has a flared shape, fits the carboy one snugly as well:

So here we are with a very neat looking gasket to fit in the airbox:

If you like to, it is possible to glue the pieces together with a suitable rubber glue too, but I shall say that is not needed at all as the air filter holds the flared piece of the black gasket perfectly, while the carboy gasket part is held in place by the original outer ring of the Ten:

So let's place the gasket gizmo where it shall sit...

...And screw back the outer ring in:

Easy Peasy! And damn cheap Stage2 filter I must say! :icon_thumright:

Looks good! :023:

As long as it's rigid enough to hold things tight you should be fine now.
