He lifted that pic from JeffD's Rejetting tutorial on the GStwin.com GS500 Modifications Page.

sounds like the same problem i'm havin, i got fed up when we tried to get it runnin and all it did was backfire, i took it to the shop, threw them the key and said fix it, i obviosly can't.

I wanted to get it to run by myself but there was no way i was gonna get it.

Good luck

I knew nearly nothing about engines two weeks ago, but I've been working on my new gs500 to do some troubleshooting of a very similar problem.
When I checked my plugs they were coated thick in carbon which caused them to produce weak sparks leading to incomplete combustion. Combustible gas exits to the exhaust and you get a backfire. Try replacing the plugs, or at least see what kind of spark you are getting from your existing plugs. Mine were giving weak orange sparks. I am a newbie diagnostician, but the comment on black plugs and backfire rang a bell.
