Just installed 3rd sbt engine on my 2003 XLT800. Carbs were rebuilt using sbt's kits. Popoff pressure was set at 40 psi. Low and Hi speed adjustments were set 2 1/4 out on Mag.... 1 7/8 on PTO and Highs at 1/2 out on both Cylinders. As I was performing the breakin of the new engine I observed the following: 1. After running each 30 minute interval and and letting it rest for 30 minutes ant then try to stat it again, the engine would flood. After the first time this happened the only way I could get it to stop was by turning off the fuel cock during the cool down period. Even then it requires much effort to start it back up. 2. It is sluggish coming out of the hole and did ok when performing the 90 % throttle breakin step. 4. I put 50:1 in the fuel tank and my oil tank was full when I started with the full tank of gas. During that first tank of gas the level of my oil tank did not seem to change at all. My other 2003 XLT 800 goes through about a 1/4 tank of oil per full tank of gas. I plan on continuing premix until I work out the the oil issues. What is the correct premix ratio for a 2003 XLT800 after the breakin period?

Re: Carb Issues?
There's no way your pop-off is correctly holding at 40 psi, and also letting the motor flood. Replace your needle & seats.
Your oil pump is obviously dead, if your tank level did not drop. Change it or remove it now. The stock ratio is 32:1SBT Tech Support is here to help with your problems.

Re: Carb Issues?
Don't throw in numbers for a different engine, someone might get confused.
The fich shows the xlt800 uses a 90 and 150 with a 1.2 N&S.SBT Tech Support is here to help with your problems.
