AHA! Mystery exhaust identified (Cobra F1r), now what?! (ie...jets)

[motokurt]

Hi,

So thanks to all the lads at GS500 wiki, I found a pic with the exact same exhaust on my bike that I couldn't figure out what it was!!! Now, does anyone know what I need to do in regards to the  jets on this beast? I am pretty sure that the P.O. didn't do anything but slip the exhaust on...

So, in order for a 2002 GS500 to run well with a Cobra F1r exhaust what size gets to I need, and how many turns back out from flush on the air mixture screw...?

And go!

Thanks!!!
