I've been running a 2 stroke for a few months now and recently switched over to Opti-2 100:1 (I misjudged a little so it's actually more like 80:1...). My plug's looking very gray, but it's an NGK BPR6HIX Iridium, so I'm not sure what to expect exactly. It runs pretty well, but bogs down a little bit occasionally at WOT. Gonna do some jet changing soon.

Here are some pictures: https://imgur.com/a/CW6qU3j

Any thoughts on how it looks? Thanks.

I think I need to run a smaller main jet, because it gets noticeably more power at WOT when its fuel is low (running more lean), but I'm afraid it'll be too lean (plug looks lean as is).
