Hi all,

I've done a search on the forums and couldn't find an answer so i thought i'd ask here.

I have a 2009 GS500F that I've converted to a naked bike. It is 100% stock other than cosmetic changes.
Currently only has 10K kilometers and runs magnificently.

I'm about to purchase a Delkevic 350mm oval slip on muffler for sound and aesthetic reasons only.

Those of you who have installed slip ons my question is

1. Did you have to re-jet?

2. What symptoms would i be looking for if it were running too lean after the install and would it be very noticeable?

Thanks in advance,

Cain
