Btw, when for giggles I added 4 qts of Golden Spectro 4 20w50 to my Amazon cart, instead of $7.99 as the listing for the oil claimed, the shipping charges were free, it was $10.99/qt
considering Castrol Racing 4T is $8.99 at local Advance Auto, that is not a bad price.
Bike is going to shift better, clutch work very well, and run nice and there is no fear of the oil not having enough zddp.
