I have a 2003 954, i bought it used with 13k on it in 2007. I do wheelies all the time, every time I ride I do at least one. (throttle first gear or second,clutch second and clutch+bounce third for highway wheelies) End of 2009 summer, my trans started slipping. I found a spare motor with problems and swapped the trans out. In Feb of 2010, I started hearing a clicking while headed home. Let a guy listen to it and told a couple other bike mechanics and they say third rod and/or piston or crank. One guy said "that year honda's do that, because your draining the engine of oil when you ride a wheelie for long time". Now I have seen a lot of guys stunting on 929's and 954's, am I killing my bike or is it just bad luck. Anyone stunting one of these or riding a lot of wheelies, please let me know if you've had this problem. Feel free to email me at rpm_rippa@yahoo.com too, i check that more than I get on here. I also believe i heard of guys adding or changing the oil suction tubing. PLEASE, ANYONE WITH INFO PLEASE RESPOND.

 

Sounds like your timing chain tensioner to me, my 900 does it once in a while. A knocking is a piston or rod bearing and a clicking is the clutch basket or chain tensioner on the timing chain. Hard to say unless I listen to it. I stunt my 900 more then my 600 and with hondas no problem, I just run 1/2 quart oil higher. Johnnyh

 

I've been running a full quart over capacity on my 929 for over 10,000 miles with no ill effects. The 929 and 954 don't need to extend the pickup tube because it doesn't effect the bike to run extra oil.
