I repeat,There is absolutley no problem in using a 5W40 in place of a 10W30.
Just give it a layman thought atleast.
The CBZ X/Hunk share the engine with the Unicorn which is recommended a 20W40 grade.(Except for the slightly modded cam)
And the earlier Zmas were recommended 20W40 and the Zma R s are recommended a 10W30. They both have the same engine. The key here is higher FE in using a thinner oil.
Also, ironically the HH guys pour in 10W30 oil when the Previous GEN Zmas go in for a service . Just give it a thought.


. Does motul have any product with similar grades as HH recommended?
God knows whats in store when I open up my baby
. I guess I'll have to get it done from some other mechanic. I'll sureely get some pics of the filters.



but i am sure it was not a manufacture defect.Its some minor issue
.After the CBZ guys took everything(rear wheel ) apart sandpapered and applied some paste(maybe grease
.How does oil reduce tappet noise by this much
