How does my jetting sound 250r/310?

[WEATHERBY460]

86 honda atc 250r with a 310 big bore kit.

paul turner exhaust
k&n air filter
keihin PJ
160 main
48 pilot
1.75 air screw
br8eix plug
40:1 premix amsoil interceptor
93 octane gas

Any idea is this is good or not?

Every machine is different. Pull the plug, check color, and continue doing plug chops till you get a dark brown on the plug
