Engine Oil Viscosity for 2014 Models

[Pterodactyl_imp]

At 600 miles I did my 1st oil change on '14 deluxe using Honda HP4 10W-40. Every time I have rode after that oil change I heard new loud ticking noise when the bike warmed up.

Last night, I decided to drain the 10W-40 and put 10W-30 in. I have ridden the bike 3 times since then and have not heard the ticking noise once.

I noticed the 2014 owner's manual makes no mention of any other viscosity other than 10W-30.

Previous threads indicated that the 2013 shop manual indicated that 10W-40 was an option. Can anyone validate if the "2014" shop manual lists 10W-40 as an acceptable weight? Thank you

I live in Reno, NV (temps ranging from 70-95 degrees).

For that temps range the Honda service manual suggests 10W-40, at page 3-15 of the German version of the 2013 manual.

I think, the 2013 manual is also used for the 2014. Here in Germany there exists an extension manual for the CB 1100 EX with some extra information relevant for the EX.

That is in line with the '10 model owners manual. But what would Honda know?

Cheers
