Glad you liked the title Brian, that's about as Biblical as I get! :)
Thanks for clearing up the "Europed" thing also, Fred.
I changed the plug over the weekend along with cleaning the air filters and changing the tranny oil (it was black and watery.-Eeuuww!). I had leaned the jet needle one notch, and sure enough the plug was a lighter tan than the one I'd removed a while back. It still looks healthy though, less carbon depositing also. The ceramic did have a small circular defect though, like a piece had broken away. The plug has the ceramic slightly further out, unlike the first one or the one I'm using now, so perhaps it's a matter of exposure.
The only problem I can see for a plug chop is that full throttle and top speed aren't the same thing on my machine. I can get it to its' top speed of around 75Kph(47mph) by using half throttle. I generally increase to just over half, the RPMs building up, then drop it a tad and it accelerates to its max speed. It will sometimes "stutter" at around half, but less so now that the needle is leaned. Opening the throttle full gains nothing in speed, unless it's on an incline or I've got a pillion. Then I can sometimes get a "surge" to top speed. With two people, this surge usually "stutters", pulling forward and back.
I know at what throttle position the main jet should be effecting it at, but I'm not certain if my higher speed is done on the needle or the main. It seems to be more in the needles' range, which coincides with the "leaner" plug.
All of which makes it bloody difficult to be certain of what's going on in there. Anyone got a VERY small camera? (Or should that be camel?)
