Thanks for the step by step guide gg3, it was a massive help and made the job easier than expected. Here's what I found:
Pilot: 42, Needle: N1EF, #3 clip (third slot down from the top), Main:175
According to the manual this set up is pretty much perfect for my temperature and altitude - so why the lean looking plug?
Also how long does it take for a new spark plug take to show colour so you can read it?
The reason I ask is, after I rode in the sand for that hour and discovered the lean spark plug, I wanted to test if it was lean just on the main jet, so I let it warm up for a few mins, then rode 5mins down the road using 1/4 to 3/4 throttle, with maybe a few squirts of WOT. This was on hard pack so not under load like I was in the sand. I checked the plug again and it looked pretty much the same.
Is 5mins enough to read a plug? If so why is it so lean even on hard pack terrain?
Finally does fuel octane have a major effect on jetting? Like is there much of a difference running 91 as opposed to 98.
