Hi All,
Long time reader, first time poster.:Lurking:
I was hoping the wise Fz6 community could help me out in a very awkward jam.
I've been riding a 2006 Fz6 which I bought with about 6000 miles on it and have had a joy after riding for about 500miles, but recently noticed a subtle knocking noise coming from the engine around 4-6krpm. After hearing this noise, I quickly researched and found it could be a faulty cam chain tensioner. Okay, installed an APE tensioner, no real change in the amount of knocking.
Now, after letting the bike sit for about a week, I decided to take it for a spin on the local highway. On my way home, a TERRIBLE knocking/rattling between metal. Luckily I was REAL close to home and coasted it to the garage. Now the noise is pretty damn loud and happens at any rpm. Just to get a sense of how bad it is, I do NOT want to start the bike with the problem. Maybe an example of the sound would be smacking a metal can with a drum stick.. :banghead:
Time to take the bike apart
The first thing I checked was the oil and anti freeze, perfectly clean. No metal debris. Ok :thumbup:
Then off comes the valve cover, hmm, the cam timing is perfect. The timing chain is fine and no debris anywhere in the engine. The engine turns easily using the crankshaft bolt. :rockon:
And this is where I ask you guys/gals. Any suggestions on what could possibly be wrong? I feel like if something was broken metal debris would spit out in the oil or antifreeze, but nothing.
Any suggestions would be great, or perhaps a link to a similar post. Couldn't seem to find anything similar myself.
