Thanks Pleiades, i had the same thoughts. I have it now set to +3, that is as far as the trimmer goes. Will try it out as soon it stops raining...

But i would still like to know more about the device, since there is so little info around. So any info is welcome.

There are two trimmers, first goes from 1 to 7 and says "setting". Setting for what? Manual says to set it "6 for stock bikes, 5 for bikes with aftermarket exhaust". What does that trimmer do? Should that go down with the stage 1&2?

Second trimmer says "fuel ratio", so thats a dead giveaway. It goes from -3 to +3.

Manual does�nt explain anything, it�s A4 piece of paper. It only shows how to install it, and the recomended settings for the trimmers with aftermarket pipes. Emailed dimsport(manufacturer) but they seem to be busy with something else.
