ive got a 01 929 w/ about 15k miles on it.never really noticed it last season but this season im hearing a tapping sound from the motor. it only happens when im decellerating, kinda faint from wind and road noise. but when im slowing down, just downshifting into first i burp the throttle just a bit and when the revs fall i can hear the tapping. like i said its more pronounced when i do this b/c less wind and road noise (it does it any time the revs are falling from around3-4k rpms). doesnt matter if the clutch is in or out.

thanks

 

what octane fuel are you running? If its to low the motor will ping slightly. Try running premium and maybe some fuel injector cleaner.

 

i hear the same noise from my oo' with 16,000 miles and i only run premium fuel. could it be valves or cam chain tensioner??

 

its not a ping. my dads 400ex pings when it doesnt get premium at the sand dunes. i know that sound. ive been running regular since i bought it. put 2 tanks of premium in a row once and notice no difference in sound or preformance.

these last few days have been warm and its definatly noticable when the bike is warmed up. i wouldnt say its a cam chain noise b/c its too low pitch for that.

im running Havoline 10/40 regular oil in it and was thinkin of swithcing to semi or full synthetic.

hoping its not a valve out of adjustment. looks like a weekend project by my 954 manual. will have to get teh specs for a 929 if i do tackle it.

 

i was told you are supposed to have a bunch of stuff done at 16k. all stuff to do with the valves and whatnots. sorry about my verbiage but i never got it done and have had no wierd noises with 21k on mine. i would suggest calling the honda dealer and asking what all is involved with that, could prove to be beneficial.

 

is that havoline 10/40 designed for wet clutch's?

 

check the spark plugs. one may be backing out. do a search on there for stripped spark plug and you'll see a few different posts (like mine) where people have had their spark plug (usually #3) actually back out because it's stripped. the first thing I noticed was a tapping sound like a valve that was out of whack. kind of a pain to get to under the tank/airbox but check it early to avoid all the pain in the *** I had to go through

 

ill check them out. thanks for the suggestion

 

i dont want this to sound gay or anything but id like to give ibkevman a kiss!!!

my first plug on the left side was about 1 full turn out. you just saved me a boat load of $$ and a pain in the ***.

Thank you ibk
