are these suggestions even Half serious???
Its a brand new R3? Take it straight to the dealer!
the spit on the valve stem is the first thing I would do. If you see bubbles, tighten the valve.
After that, check all around the tire tread for something sticking into the tire.
Then if nothing shows, take the entire wheel off, set it in a clear bath tub of water or something like that.
Look for bubbles.
Dude...brand new bike.
A leaking valve is simple, sure, but not everyone has a valve tool to tighten it up.
Taking the wheel off, etc? Yeah....Dealership. Again...brand new bike.
End of story.
Almost everybody has one.
That's even if the damage is covered under warranty.
If it's something in the tire. (They will say it is any way)
It won't be covered.
