So I recently did a service on my TTR after I bought it. The manual says 10w30 or 20w40, but I went with 10w60 (local motorcycle store is pretty high end so they mostly cater to hardcore enthusiasts). Is this ok? I've read on some online forums that it may cause more wear over time on low temps like at startup.
A noteworthy mention is that after the service I noticed a clicking sound which is synced to the RPM. My Initial thought was that it is related to the sprag clutch since it does knock quite a bit on start and stop.
The only things I've done between before I became aware of the clicking and after is the oil change, oil filter clean, air filter clean, new spark plug, new 10w60 oil and probably 100 kicks on the kickstarter (starter brushes wore out. fixed it during the service).
