The Sunline 60RRS seems to be hitting against the diffuser. The stock mounting for the muffler is too soft to hold the muffler tight. Went Project S to change the stock mounting. The Greddy muffler mounting is not cheap hence just got 1 changed and the other rubber mounting is stregthen with cable ties.
It's been awhile since I used the Selenia Star 5W40 engine oil. Here's the average FC. No changes on my driving style and it really improves the FC from 12.5 to the current 14.4. By the way, I am using Shell V-Power.
