awesome RR...
my engine is making a slight rubbing sound... not sure if i never noticed it with your bike because of the yoshi. but it sounds kinda like two sheets of paper rubbing together, only fainter and each 'sssshhhh' is longer. oil is above the bit on the dipstick with grooves on it, and 1/3 up the thin sticky bit (couldn't find the F or L marks last night). should i be concerned?
