SLP Race Twins jetting???

[oddfire]

I have a question...

I threw in the towel on my tired gen2 chassis and have dropped my 01 snow check 800 (non VES) in a 03' Vertical Escape chassis.
I have used...
gutted edge air box
edge carb boots
stock 01 primary
cat secondary
...and will be using a set of Edge Chassis SLP race twins and stingers

How do I figure out what jetting I need? I was told this motor has a "mild SLP port job". Carbs are jetted for a SLP single pipe/can/Y pipe that i am now selling.


Thanks!!!

I run SLP twins, not sure if they are race though? Mine is an 03 so jetting is DIFFERENT. I run 490's with an ATACC installed, 69.5g at 2200' and 63.3g at 7400'. Team tied secondary. I also run 20% 111 octane, as it says you should too when below 3000'.

SLP has a jetting chart on their website:

Are you going to be changing altitude with it or not really? I strongly recommend an ATACC if you do. The 490's i have in it are for -30C as that is how the ATACC works. SLP recomends i run 540 at -30 so that shows you how far out they are at low elevation. I am told they are very accurate at 6000' and above though.

Just thought this may help for comparisons sake.

Thanks, I usually play between 3 and 6 thow. Have thought about a Holtzman, but have heard so many good and bad stories that I have not made up my mind yet.

BTW, I am running the factory carbs from the 01 Snow Check the motor came out of.

I have gone from 2200 to 7400' on two seperate weekends and the ATACC performed flawless. I think the biggest thing is getting them set up properly from the get go (main jetting for coldest and lowest alt.).
