Do i have head gasket issues?
As the title suggests im looking for some answers about my yamaha xj6 head gasket.
Symptoms are a very brown chocolate colour oil.
Coolant level seems consistent and is clean (blue).
No bubbles from an open radiator cap on cold start.
No froth or foam of any kind in coolant or oil.
Oil has a noticeable dark grey shimmer which i am 90% confident is caused by use of mos2 additive.
The bike runs fine with no sweet smells. Just very brown oil colour. (Oil is motul 7100 with 2500 miles)
Does this sound like a head gasket or do I need more regular oil services?
