Not sure off the top of my head. I will check when I get home from work. I will read into the white spacer mod. I plan on doing a cam/piston upgrade down the line. I heard the Mikuni's were superior. Any thoughts on that?

To Lancer’s point, you want genuine Mikuni jets for the stock CV carb or if you switch to a Mikuni VM36 slide carb.  Lancer sells a VM36 carb kit and also genuine Mikuni jets for either carb.  As well as his other goodies - hot cams and pistons.

The 6sigma website is a bit of a black box.  Even when I added the stage 1 kit to my cart (playing around with them), it didn’t tell me what I would get for $50+ bucks.  No thanks.

If you don’t want to buy through Lancer, you can buy genuine Mikuni jets from JetsRUs.com.  They are like $5-$8 each and like $8 shipping.  That’s much better than a $50 kit that you don’t know what you’re getting.  They also have the “washer/spacers” for the needle, or you can get a half-dozen of the right sized washers at a hardware store for less than $1.

The Mikuni VM36 is a great carb.  Lancer and his followers can attest and he’s sold many to happy members.  I like the VM36 a lot.  I also like the Keihin PWK38 a lot.  The biggest difference when running a slide carburetor is throttle response.

DragBikeMike did a great “carburetor shootout” technical post comparing several carbs.  Link here —> http://suzukisavage.com/cgi-bin/YaBB.pl?num=1585461605
