my bike has been making weird noises...
the most recent one is a loud hallow sound while riding around 5 -6 thousand rpms, kinda sounds like there is really little gas,,, full tank though
second one, is a annoiyng!! hissing noise,,, even there while not riding, sounds like somethings loose somewhere
third one a puff from the front clyinder from take off somethimes
any ideas what they can be?
A puff from the front of a cyl. and the hissing I'll bet are related and I suggest inspecting the exhaust gasket of the offending side.
