My sling is running rich, it is supercharged with 1320 header and Welter dual exhaust. At idle it sounds like there might be a slight pop in the exhaust. I pulled the O2 sensor and plugs. Video is ok not great, might need better speakers to hear the pop I'm thinking I'm hearing. I'm planning on replacing the plugs but not sure the gap needed. Any help or suggestions are welcome.
Diagnosis of Rich condition
-
Check for an exhaust leak?
-
Dave@DDMWorks any Ideas to help from the SC doctor?

I'm not a supercharged expert but I have stayed at a Holiday Inn Express before. MOST of the boosted tunes do run a bit rich (if you have a wideband O2 sensor and gauge, you can see the actual numbers.). It's always better to have it a bit rich for safety reasons than an equal amount lean and cause issues. The exhaust popping sounds are something common with these systems as well. As Mitch suggested, checking for an exhaust leak is wise, but even a properly installed and sealed system can and will have some popping sounds under the right conditions. It may not be what you wanted to hear, but there are several of us that have the same or similar issues with no other causes to blame it on.
I'm sure Mr. Dave will chime in when he can with his thoughts
-
Fire it up and run your hand around all the connection points (exhaust flange, muffler clamp, etc) feeling for any hot air blowing out.
-
Welter cans don't need to be repacked maybe?
-
Instead of putting your hands near hot exhaust, get a rubber hose, put one near your ear and use the other to "listen" around the exhaust connections. It's a poor man's stethoscope, but it works well to pinpoint leaks.
-
For boosted applications we typically gap the plugs to .035 Dave may have a better recommendation for his SC kit.

Those spark plugs look clean compared to the ones I have changed on the turbo set up. I know mine is running rich...when I go in reverse, I can see black smoke from the exhaust. As far as the popping. I know on my set up, it's been getting worse and worse. I know I have a rattle in the muffler and need to replace it.

It seems that tuning(NA,TC,SC) is what introduces popping, one of my slings was stock for close to 3 years and never popped but every since I tuned in early summer it pops often .
Now with the tune this machine feels like it belongs in the Wild West , have to be mindful if i drive by "certain areas" so I don't trigger a shootout war.

Have you changed this?

I'm glad my stay at the Holiday INN Express wasn't wasted

I've tried for YEARS to diagnose the RICH condition, but alas, after buying the Slingshot, I'm forever forward part of the FORMERLY RICH crowd that now lives paycheck to paycheck

You are rich in your own special way my friend.... hope all is well

Thanks Mitch. Not sure how well is well anymore. Waiting to hear when the next surgery is going to be scheduled. If I knew I would be living this long, I would have taken better care of myself when i was younger

Funny how that happens just like canned food - it is good way past the printed expiration date.
We are happy to have you around
