hey there. i had to do spark plug chop tests today and re-adjust my air screw. I followed the jetting guide 101 again and got the engine to operating temperature, ran and rode the bike for a bit however when i took the spark plug out(engine stopped), i noticed smoke coming from the hole where the spark plug screws into...is this normal because the engine was hot? or will it have done damage to my cylinder/piston?? It's a 2 stroke Yamaha YZ 250.
i know it may be a bit of a stupid question but I just thought id ask, make sure and know 100%.
