I didn't know that about dwarfs!

To do with viscosity, the important question to ask the dealer is - what was in there before? I appreciate that 15w50 might be more appropriate in your climate than 10w40, but as the problem appears(?) to have reared it's head after an oil change, was there 10w40 or 10w50 in there before? This may explain why things feel different? Speak to your dealer.

As your bike's still under warranty it is worth raising these sort of questions. If (god forbid) you do have a problem later, then if you've raised concerns earlier (within the warranty period) you'll have much more of case should anything happen in the future.

But don't panic!
