Shall I get very worry???

I recently bought a second hand KTM 950 ADV 2003.

http://advrider.com/forums/showthread.php?t=1017469

Running the bike on the stand I noticed that the fumes that come out from the right can seem to have higher pressure and they even become hot faster.

Shall I worry? Shall I worry a lot? Does it means that the rear cylinder is gone??

It is currently running Leo Vince cans. Today I took down carbs and moved the needle to its original position to fit the original cans (that I haven't done as yet!).

No you should not worry. It's meaningless and they all do that.

my 990 FI model does the same, the front cylinder seems to rum cleaner / leaner i guess....the FI map clearly shows a difference in the mapping between front and rear cylinder...don't know why

Rear cylinder on v-twins typically runs hotter, thus the larger jet or richer program on the rear cylinder to help keep it cooler

Normal. Noticed the same in one 950 and two 990's. Ride it!

Tried to figure if was the same in the 1190 but those ingenious only made it with one can..... a heavy one....

The issue that slightly worries my is not as much the difference in temperature but is the fact that the fumes that come out from the left pipe have definitively a lower pressure

????

There's a crossover in the mid pipe between the 2 sides. You'll never get equal from both pipes.
