Emoticon_unhappy  "tap-tap-tap" intermittent sound...WHY
Hello Everyone. I NEED YOUR HELP. I need your analysis. I'm hearing some intermittent tap tap tap sound on my 04 650C V-star. when i hold back the clutch , sounds goes away. when i throttle at say 2-3k reps...sound comes on....i throttle up some more ..sound goes away...release throttle...sound comes back on. WHAT THE HELL IS GOING ON ????? all this i laid out is in one motion. when lower than 2k sound.

I checked for the usual suspect rattles. nothing. everything tight up pretty good. sound is coming from UNDER the fuel tank...right were u have the top of the engine.

Please....ANYTHING that you can think of as the CULPRIT, suggest it. I'll tick them off one by one...til you guys help get to the bottom of this STUPID "tap-tap-tap" off-and-on sound.

hoping your issue got fixed, but i'd personally say its probably just pinging from too low octane gas. try to keep good fuel in it. if it still taps you might be smacking a valve or something else.
