lf you are running NGK ES type plugs ( you are supposed to read the top electrode mainly on ES plugs)
l run dial a jets, so to me those plugs would look to be on the perfect setting IF,
l was running as cold temp as i ever did,
That the plug reading was taken at the end of a very long WOT run.
l was as low as i was going to be elevation wise
lf i was running straight jets foir trail riding i would go up a half size ( if you are running pipes, you could go up a full size with stock pipes, there more forgiving). ln my location and riding style that would move what i call the tide mark (dark carbon area on the electrode) up the electrode 1mm-1,5mm.
For me, for day to day trail riding your a little close to lean for my liking. As youve very little to go if you get caught on the lake and it gets real cold etc
Race day perfect. l cannot speak for Tony,to me race day perfect means around 5 degrees air temp and 10-20 % humidity from a lean condition
lf your tuning aaen 800cc pipes on a 750cc dont be tempted to lean it out any further
