fast tapping noise...
i used to have a cutlass with a 350 in it, sometimes when i would floor it the engine would make a tapping noise. i think i learned that the noise was from the "lifters" or "valves", im no gearhead persay...
anyway, i have noticed this a few time on my KLR. usually at the end of the shift range for me, around 4500. also when under load or going up hill and giving it the berries it will wind up nicely then hit the tapping sound. its not incredibly loud like the engine is falling apart, actually at first i thought it was a rattle from radiator area.
i guess my first instinct was that maybe i needed to check the valves, may need shims.
my bike is an '05 and i have 6600 miles on it.
