Default DIY- Removing the Snorkel

edit: Mahalo, Celly, for reposting the pictures so I could use them.

The other day we got into a discussion while raising the needles in the carbs and we agreed that intake modifications would be next. Raising the Needle Jets..Mod.

Unless you are going to individual pods, the next best you can do is to open up the stock airbox. There is a snorkel that leads into the airbox that is used primarily for noise reduction. The discussion rolled around to removing it and after looking in the service manual access to that snorkel by removing the airbox would be a royal PITA. Sigh, so much for that idea.

Or was it??? Tonight while doing something else on the bike I decided to take a closer look at how that snorkel was in the box and if it were possible to remove it without removing the entire airbox. Good news, boys and girls... there is.

Before I show you how, let me say that I have raised the needles in the carbs and as is the bike runs a step richer than stock. Removing the snorkel lets more air into the box by providing less restriction, meaning the bike will get more air, therefore run leaner. I bring this up only to caution that I do not know how your bike will take to this removal without jetting changes, but be warned... it could cause your bike to run too lean, which is not a good thing.

But, I will say after I removed the snorkel, the bike idles even better, throttle response is improved and best of all, the bike now has an intake roar when revved that is very similar to putting an intake on a car. The hissing sound of of air being drawn into the motor at idle and when revved, a deep resonant howl is heard. Mind you, I have not even taken the bike out for a ride... this is only while idling and blipping the bike in my garage. Can't wait to hear it at redline.

For those that complain that the stock exhaust is too quiet, this is something you should look into.

Enough of the babbling... on to this easy, rewarding and free mod.

First, remove the airbox cover. Here I have the side cover and rear body panel already off. I was doing something else, so I don't know if you need to remove the rear body panel.




next, once cover is removed, this is the stock filter in place...




slide stock filter out. Remember which side of the panel faces the engine. you don't want to reinsert it later with the dirty side towards the engine.

Next, put your hand inside the airbox from where you removed the filter and push the snorkel back out the rear of the airbox. it is only pressed fit in there and has a weak glue around the outside edge for water proofing, I guess.




Here you can see the snorkel fully pushed out of the airbox.




pull snorkel out.

Hole in airbox after the snorkel removed. You now have that much more of an opening to draw air from.



this is what the inside of the snorkel looks like.





Reinsert your air filter with the clean side towards engine and put the airbox cover back on. I also have the rear body panel back on in this shot and it looks like you would not be able to get that snorkel out if you did not remove that rear body panel.


Bike all buttoned back up to show how the panels form an enclosure around the region where the air will now be directly drawn into the unrestricted airbox opening.

So hopefully this isn't too dumb of a question... but I will be finally picking up my blue 250 this weekend and it is going to be my first bike. I have the Area P exhaust, jet kit, and plan on doing this minor mod. Is there any reason why I would want to wait to do all of this until I have the bike broken in a certain amount? I was thinking about it, and would it be better to keep the more restrictive exhaust and intake on the bike for a little while to make the bike work harder, making it break in better? Or is that completely wrong? Just trying to decide what is best from some of you who have experience breaking in bikes.

Thanks
