A 6000 mile change interval is reasonable, and I could live with that.....it's those that feel it necessary to replace them every 1500 or 2000 miles, that I don't understand. If it happens that your plug is shot that quickly, your scoot needs more attention than just a plug change. I too ran a bit over 6500 miles last season....Though not all on my scoot, because I have to split my riding time up between it and the 2 bigger bikes. Scoot logged 2,773....Schultz logged 1,586.....Dooley logged 2,164 [img src=" ![]() i1271.photobucket.com/albums/jj622/rks3526/photo.jpg" src=" " alt=" "] |

I usually change the plug boot once a year, too. Changing the spark plug once around spring and once around mid summer doesn't seem like much overkill to me. A lot of riding coming up over the next 4 months. I normally like my ignition system to stay at 100%, and it's cheap to do so. I also need to rewire/extend my wire coming off the stator that fires the plug (at the mating point)-- i only have the wires twisted together for now wrapped in electrical, just not much room to work with after changing the connectors awhile back.
I'll get back later on my plug-- worky work.

I put more miles on that stock plug than originally thought-- it's closer to 4,500km. I took pics of my odometer during oil changes and looked back. Quite unusual, normally I put 2 new ones on a year. My scooter came in the shipping crate with a NGK C7HSA plug. That same plug is still in there, after 3 seasons of riding.....about to start season 4, if we can get some of this snow melted. With 5,800 miles operated, which is more than twice as much as 4500km, I have no plans on changing it until at least next year. Scooter starts and runs great, and the last tank of fuel I used, delivered over 91mpg.....not bad for a 150. I know plugs are not expensive, but I can't see throwing something away prematurely....especially when you gain nothing in the process. In the last picture you posted, the gap in your plug appears to be at least twice as much as it should be.....don't know what you gap your's to....I run .027". Anyway, you're right, the gap looks larger than what it should be. The way the ground strap has worn away is probably part of the problem and isn't helping my eyeballs either. It's the plug that came with the engine, not sure why I never checked it. With a new engine, I usually check to see what brand plug (and buy an NGK) they put in but not this time. If I did I may have noticed the gap. I can't say I've ever had to gap an NGK plug though. The one in the pic isn't NGK. |

The plug ground strap (little hook at the end). I took a pic with three spark plugs I had. The one in the middle is the plug in question, and is noticeably shorter than the others. It also looks different, not just shorter.  |
