A little update........had a great day at the race in Riverside yesterday, the bike ran better than ever and was surprisingly fast with the new mods and some race fuel I blended up. I didn't mess with checking the plug to see how it was running at the track.....really didn't need to.
So I pulled the sparkplug today to see how it faired after a hard day at the track, and this is how it looks:
This is the original sparkplug with less than 40 hours on it in the one year of racing it.....not bad.
With the new jetting and higher compression, I think it looks about right with the new fuel blend. The bike was geared right and the acceleration was impressive.
The only probs I had at the track was about 130 thorns in my tires (from over-shooting a turn) and the bike stalled on the take-off of the finals which killed my chance for the win, but I still placed very well considering.
