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

Great testimonial, Ruttly!  Where do you draw the line on stock vs modified?  I think Lancer tried the 38mm with his hot rod and dropped down to the 36mm for better performance.  My memory is bad, but I think it had to do with the velocity of the mixture through the intake valves into the motor or maybe it was better fuel atomization (or both).

I’m toying with the idea of experimenting with a PWK36 instead of my PWK38.  My bike is what I’d consider stock - just a UNI foam filter and Dyna muffler (no hardcore Stage 3 stuff like hot cam, hi-comp piston, bigger valves, porting, etc…).
