met a guy at Orca Bay demo/dyno day who raced a first gen SV at Mission and was doing some tuning with the dyno over the summer. He had them under his front tank mounts to allow more airflow to the airbox intake. I just have the washers there to try it out before I had some made up as the bike shops don't sell them. He had many cool parts on his bike but all from various machinists in the USA. And all his stuff was for the 1st gen and I don't know if all is the same for the 2nd gen motor wise apart from the carb/FI change.

ummmmmmm prolly no one makes em cause they don't really work. the tank is in a low pressure area of the bike behind a fairing so not gonna get much air cept what's around it and you.

Actually, this does work and many Sv guys do it. You could always just use a bunch of washers stacked on top of each other. Check http://www.sv-portal.com for more information. There is tons of info there.
Also, if you're looking for rearsets, check http://www.onesecondfaster.com

You're right, tank risers do help. But they won't do a bit of good if your airbox won't let in the extra air. Stock SV air boxes are very restrictive so it is worth your while to alter it. Once that is done you should get on a dyno to remap your fi system. It may seem like a lot of trouble but in the end it pays off. How do I know this? My latest dyno was 88 on pump gas and 93 on a race mix 
. Not bad for a first gen! And I just use the washer method. SVRider.com has a guy who sells the solid ones but I can't remember who or how much. My washers cost under a buck...

If you offer this little bit of info then, you could then tell us in which way the air box would be modified. Who's altering it or is this something riders could do. At least explain what your talking about.You're right, tank risers do help. But they won't do a bit of good if your airbox won't let in the extra air.

One example of an air box mod is for a DRZ400. Its called the 3x3 . You cut a 3" by 3" square into the elipitical air box opening. You need a photo which I have to show you where to cut.

·ive seen the tank raised thing on a lot of gixxers as well,,i wouldnt do the washers thing ,no point in adding weight cuz generally washers are steel (not a lot by why bother if you dont need to ) yu can use some lightweight aluminum spacers,you can make them from aluminum rod stock .

How do you go about modifying the stock airbox? (in my case, its a 1st gen bike). And which filter would be best to replace the stocker?You're right, tank risers do help.

He's local here in Vancouver area so you could pick them up from him.

I have heard many ways of the airbox mod. one is to drill a whole bunch of holes in the lid. Another I have tried is the SV 1000 snorkel swap which is the same fit but alot less restrictive. When back to back dyno runs, the 1000 snorkel was 0.4hp less than my stocker. Maybe #'s would improve with my airbox hacked and running in open air rather than a fan blowing in front of my bike. Maybe not enough airflow to make a diff.

The airbox mod I'm refering to is de-snorkeling. Cut the snorkel completely out of the filter. I used a 2 1/2 hole saw ( I think) to remove the lip and all. I stayed with the stock filter as that is what I received the best results with. A Dyno-jet jet kit is pretty much a requirement; increase the air and you must increase the fuel. Not sure on the hp gains with just those 2 mods as I changed my intake cams as well and went from 67 to 75 rwhp.
