40K mile service questions
Anyone else experience their ninjas valves never moving since the initial inspection? My initial inspection was at 12k with every valve needing the next size shim then 20k, 30k and now 40k with no adjustments needed. I'm not complaining, it just seems to good to be true. And you guys know I ride my **** hard from time to time so it's not like I'm babying it.
The other thing I noticed was my spark plug electrodes are going away. I'm not even going to try re-gapping since it seems like it has been eaten away at the last 2mm only. Its hard to see but you can just make out the tip is thinner at the end. These are NGK CR8EIX IRIDIUM PLUGS so they are supposed to last longer then stock. They were installed at 12k miles so is 28k good for these plugs or should I have seen a longer life? |

Please see this:

Well aside from the wear on the tip I think my plugs look perfect, I know these things are supposed to wear out but I've never knew what exactly wears out on them and how long it actually takes. On the race bikes we replace them every season just because you basically get new bikes every year and on the dirt bikes you foul plugs before they ever get a chance to wear out.
The two picture that note erosion say its cuased from lead in the fuel but I'm pretty sure Ca hasnt use lead in pump gas since the 80's-90's I'm ok with new plugs every 20-30 miles with the hard riding and high reving I do, I was just wondering if it was normal. |

I am sure the arcing wears the tips away, also if in a car these last 75-100k miles then a bike revving at at least twice the rpms and therefore twice the electric arcing, will wear them out 2x quicker.
As to the valves, my guess is they work harden as they bang into the seats and therefore the biggest difference is in the beginning since they are the softest. |

Is your ignition system stock or modified?

Aside from a stage 2 Dynojet kit and full Leo exhuast my bike is stock motor wise. I am pretty good about changing the oil every 3k miles and sooner around trackdays, and I always use motul 300v factory line oil. I want this thing to last me a 100k miles and it seems I may be on the right path so far.
