Doing a clean up on my Wing. New battery draining breather tubes. ( oh wait what's that) could have been very exciting. Check your trike. I am sure my mice are not the only clever ones on earth. I could smell something on my first short ride. I thought it was antifreeze. NOT . Found this..
all tucked on top of the motor right behind that spark plug. BTW. those are the 2 tubes that should be drained...
