96 blaster exhaust port

[Blasterjohny]

After riding I had a little oil mix coming out the exhaust port is it because I'm to lean or should I even be concerned about it?

it's normal, but if you're questioning your jetting ..... plug chop.
Get a new exhaust crush washer
apply a thin coat of Permatex high temp copper to the backside of the flange, bolt it up and allow the rtv to cure 24 hours before running it.

Clean the port area and pipe before using RTV
