Spark plug looks good after 1000kms on the Opti-2. Needle is on seconds slot down from top.

NOW THAT IS WHAT I CALL A PERFECT BURN!!!!!!!!What size engine do you have and what plug are you using????I have made the switch to opti 2 myself are you running 100:1?

I am running at 100:1. I am using the bp6hs plug. I used the b6hs, the only diff being it is not a protruding electrode, and I found that the BP6HS was mush better. It puts the spark down further into the center of the head space. Also the BP6HS is the same as the std Chinese plug. I know all the blokes here use the B6HS (Non protruding electrode) but as I said I did not like those.
And yes I am running a 66cc ZBOX Z80 motor, with a SBP Pipe and an air filter and a 36 tooth sprocket. I dont whip it but it will hit 65km/h WOT. I mainly cruise around at 40km/h.
