removal of snorkel
 

just wondering what this air filter snorkel looks like? can someone post a picture so i can see if mine is fitted or i might need to get rid of it

take your seat off and you'll see what looks like a minature ships funnel in the middle, just on the right side of the battery.

If its missing then there will be a hole approx 3-4 inches wide x 6 inches long approx.

Snorkel
 

Took me a while to figure what the Snorkel was too.:retard: Basically its the air intake for the airbox. Its there staring at you under the seat. :happy11:

should the snorkel be removed completly or cut down so you still have the lip to stop anything falling into the air box?
Ive completly removed the snorkel but am worried due to a build up of water in the small plastic tube under air box.I have put a few slices in this tube with a knife to stop any water reaching the engine (not sure if a good idea) but im still worried about any dirt etc etc reaching the engine with the whole snorkel removed.
any advice is welcomed.
cheers big ears.:o

Just pull it out and do what I did to mine, I've cut a piece of wire mesh and stucked it on the top of the hole with silicon so that nothing could fall in the airbox.

No need to worry, the air box is made up of a few chambers.

The first chamber is where the snorkel sits & can be removed, if any water enters through this opening it will fall to a second chamber which is the lowest point of the air box, on the outside of the air box on the left side of the bike there is a clear plastic hose, get a razor blade & cut 2 slits along the hose this will allow any water that has entered the air box to drain out.

The air filter is in the 3rd chamber & should stay dry. I would always recommend one to fit a oil based air filter over a paper one when removing the snorkel, the oil based filter like K&N or DNA do help repel any drops of water that make splash onto the air filter.

I have had my snorkel removed since 2005 with both stage 1 & 2 filters & have never had any problems riding in thunder storms or washing my bike.

What is the pupose of the remival of snorkel, does it give more power etc?

In a way yes, it allows more air intake in to the airbox and more air is what these bikes need to generate more power. hence the various stages of filters stage 1, 2 and possibly 3 which is soon to be issued by DNA

I have answered this question in a PM to you, here it is again just in case you missed it because of the different time zones that we all live in.

Hi 450X

This XT motor needs extra volumes of air to perform, the motor is very restrited on the intake side & responds to the air box being modified to enable extra air flow.

There is a small gain in HP when removing the snorkel, but would recommend a stage 1 & 2 DNA filters with a fuel mod which will give you around a 12% hp & toruqe gain.

Some info for you to read.

I've removed the snorkel. Uning stock cans. I find the sound of the engine very "strange" in low and mid RPM. Kind of ticking sound. Must be some resonance sound. On higher RPMs it sounds great :)

I will reinstall the snorkel and turn back the CO level on Sunday. Cause the XTX will be left at Yamaha Center for it's first 1000km service :)

I'm not sure what they like about removed snorkel and altered injection parameters...

The strange sound is from the AIS induction pipe, block off the AIS pipe & it will make a difference.
