| Have 6,000 mile on her and she started back fring when cold and surging when going down the road. Started slowly then got little worse all the time. Changed plugs were a bit black. Seemed to have fixed problem runs like new again. have the stage 1 exhaust and program in her. Was wondering if anybody else has had to change plugs already or is this a rare case. My kingpin was also tough on plugs is this a victory issue? |

Birmingham, AL 08 MC Tour Premium 2012 Bronze Mist | I've got stock pipes on mine and about 7,300 miles. I took them out and looked recently and they were really black. I picked up a new set and installed and noticed an immediate improvement in performance. I looked at the recommended maintenance schedule and it's listed as inspect every 5k and replace every 30k.

20 miles west of Chicago. | Carbon fouled plugs seem strange to me in that the Vision, especially with the S1L1 ECU program, seems to run painfully lean. My guess is that somewhere along the fuel map there is a point where they run way rich. I'm guessing this is around startup, but that's just a theory.

New Bohemia, VA | I had the stalling problem early on. When it went in for the 7.5k service, the tech cleaned the plugs and it ran like a champ. It was told to me that the EFI didn't like being started with a ride, so starting and then shutting off would foul the plugs. Also, blimping the throttle would cause fouling as well. I was guilty of both. |

| Well feel little better now that I know others are finding carbon on the spark plugs. I guess the fouling occurs so slowly that you don't relize what a difference the new plugs made. |

| Seems funny to me. Back in the '60s and 70s when I was growing up spark plugs were about a buck a piece and we would clean them and keep using them. Now they are $8 or 9 a piece and people replace them?
Does anyone else remember the spark plug sandblaster? I don't mean The Coneheads either.  )
Would it help to add top end cleaner every so often? It always helped my '99 and '03. |

20 miles west of Chicago. | The sparkplug sandblaster. When I first read this thread, that immediatly came to mind. I haven't seen one for many years. For you young'uns, it was a small compressed air powered benchtop device that used to be found in every gas station, back in the time when the attendant pumped your gas and cleaned your windshield, and at least asked if you would like him to check the oil. They stuck your sparkplugs in this device and hit the switch and a small sanblaster inside would thoroughly clean the plugs. The mechanic would then (usually) blow on each plug to make sure no grit remained and check the gap. The plugs were then re-installed. I'd really like to see one available now. It does seem wasteful to throw away otherewise perfectly good plugs just because they they've got some carbon gunk on them. Come to think of it, we dispose of a lot of goods and buy new ones rather than repair them don't we? Would anybody even know how to darn a sock? Who knows? With the economy on it's present downhill slide repairing stuff instead of throwing it away might come ointo vogue again.

Carrollton, TX | They haven't changed much. I used to use one of them on the farm in Montana all the time. One of my jobs in the shop starting at about the age of 6 was to clean the spark plugs on all the trucks, cars, pickups, lawn mowers, gas powered tractors, augers, and anything else that used spark plugs. Plugs got more carbon build up back then. |
