951cc lacks power

[TUKE]

Hi All,

I’m hoping someone may have a solution to an issue I’m having with my 951cc XP.
Every time I use my ski for the first 10mins or so I can’t get full acceleration, if I accelerate full throttle the ski wants to shut off.
Then with no warning the ski will accelerate to WOT and run perfectly all day.

The ski runs perfect otherwise, just need to troubleshoot this problem.

When is the last time you rebuilt the carbs?
What color are your fuel lines?
Have you cleaned your RAVE valves?
