Praying for a swift recovery; I am so glad this was not a more serious injury. God Bless, Matt P.

OK, I finally figured it out. Thank you all for your help! So heres how it went down: 1. I first noticed a fouled plug so i changed all of them (it was time anyway) 2. Back left plug fouled again almost immediately (so i changed it again...i know, stupid) 3. Bought Carbtune II to synced carbs (they were not really off much) 4. Checked the plug cap resistance...it was fine (i said it was 21.5ish but that was still connected to coil rookie mistake ) 5. Took plug caps apart and cleaned them (this made no difference whatsoever) 6. Decided it had to be a carb issue (I have never touched a carburator) 7. Downloaded service manual (Even though the information on the pages looked like a combination between cave art and hieroglyphics to me, it helped) 8. Opened the vacuum chamber covers (three looked fine, even though i did not know what i was looking at ) 9. Left rear vacuum cover came off and exposed the plastic screw, a couple of springs and washers, and part of the needle laying in the chamber (I am assuming that caused the carburator to flood out the back left cylinder and foul the plug) 10. Put all that stuff back together 11. With everything apart, i cleaned the carburator (I HATE ETHANOL GAS!!! ) 12. As per service manual, i blew out the carburator parts with air compressor 13. Put it all back together, and started the bike 14. Re-synced carbs 15. She is purring like a kitten (no more backfiring, and she is running smooth) I still don't know what I am doing, but learned a lot on this project. Thank you all so much for your help. Feel free to correct or critique my list; I am no mechanic (my degrees are in Sociology and Theology...needless to say, this was a learning experience) Thank the Lord for this forum! Matt Powell

Checked plug cap resistance it is 21.3K on all four plugs. What does that mean? Is that where it should be?

Greetings, I am at an end. I do not know what is wrong with my motorcycle. I have a 2006 RSTD with 8500 miles, and a few months ago I noticed a little backfiring when riding (mainly coming out of the right muffler.) It progressively got worse. I decided to change the plugs and noticed that the rear right cylinder plug was fouled (completely black.) I changed all the plugs, the problem persisted. In fact, after just a 20 min ride it fouled the new plug on the Right Rear Cylinder. My local dealer suggested to run some Techron through the bike, did not help. Also, there is a strong gas smell when running the bike. I checked the plugs and they are getting fire. I read on the forum that it might be my carbs, I bought a Carbtune 2 and synced the carbs (they were not even off that much.) No Change. A friend suggested to change the plug wire, but I quickly found out the plug wire is molded to the coil. I am not a mechanic, but I have done minor repair and maintenance on my bikes through the years. I am at a total loss. The owners manuel says that a black plug means a defective engine (I sure hope this is not the case.) Your help would be much appreciated. God Bless, Matt Powell My bike needs a good doctor
