HELP!! '96 XLT Fuel Issue

[efulton]

I have a '96 XLT 600 that runs great while cold. Once it warms up, it loses a cylinder on the top end. Seems to be running out of gas. Once you let off it, its fine. Let the sled cool down and it runs great again. I tried replacing the needle seats and cleaned all three carbs. Did not do a thing. Any suggestions would help!! Thanks!!!

Will it run on all three if the choke is on? Whats the compression read on all 3 cylinders?

the fuel pump might just be getting weak. Might be time for a rebuild.

The cylinders read 125 psi across the board. I can try running the choke next weekend when i am up there. Its just a very strange thing because it runs great until its warm.

Also check to see if it has spark on that cylinder once its warm. You might have a bad coil or a stator going bad too. I would think thats more probable since it only does it since its warm.
