Getting ready for the riding season greeted by bad sounds....

I probably better rethink that, I usually go with the manual, but when a service manager tells you something like that, you would think that it's good advice.

However, to be fair, I used 10w-40 when I did the first oil change. It is still in the bike, and I have not experienced any problems at all, no strange noises, nothing. I do a lot of stop and go, and I rationalized that the 10w40 would be better in those conditions. Next oil change I'm probably going to use 10w30, just to be sure.
