And check the plug gap ......
Spark Plug Inspection
There's a lot of misleading information out there - but this is the best link I can find for you .....
But at this point it will be tomorrow or in the weekend since I will need the bike a bit and can't mess with it haha
Take the pilot back down to two turns – and start thinking about the main jets you had on order
The pilot jet at two works for most people, and is a reliable starting point – but most of the work is done by the main jet once you get above 30% throttle
If the bike was set up by its previous owner with a leaking rubber carb boot, he may have increased the main jet to compensate
Like I said in the beginning – one step at a time or you will lose track of what worked ……
Some people called this to lean. Maybe so but it ran very very well !!!! #112 high speed jet, #40 pilot, and about 2 turns out, maybe a little more.
Same plug and engine 6 months later and still running very very well. Lots of power, very responsive.

Long live the internal combustion engine!
Look deep into the plug where the insulator meets the body. You'll see a dark band. How wide the band is will tell you how rich the motor is jetted. Here's a photo of cut plugs so you can see where to look for the band;
Timing will also affect a plug reading. The proper plug temperature range is another. Fuel can too. For example; adding oil to the gas will thicken it's viscosity and lean out a plug's reading.
Also where on the insulator color is showing will tell you where it may be lean or rich;
The plug in the middle is the correct color;
