Something loose in front end??? - Yamaha FZ6 Forums - International FZ6 Motorcycle Community Forum

Kamloops · 07-25-2008, 02:16 PM

A friend of mine who is a Mechanic and races dirt bikes, helped me tighten down the steering bearing for me.

Clunk is still there, neither him or I could figure out where it is coming from. If you sit on the bike , hold the front brake down and push forward just a little you hear it. Like something loose. Bike only has 1100km on it and is under warrenty but I have to take it back to usa for that, want to avoid the 4hr trip there if I can.

If you have someone sit on the bike and hold the front brake well you grab the front wheel and pull back and forth you can feel it as well.

Anyone have any ideas?

Its a 2007

**sportrider** · 07-25-2008, 02:20 PM

did you inspect the steering head bearing? at 1100 km I hardly think the bearing could be bad but you never know.

Kamloops · 07-25-2008, 02:26 PM

No we did not inspect it figured it had to be ok. Just tighten it a little. Bike has never even see rain or a hose. Have not got it dirty yet.

**sportrider** · 07-25-2008, 02:31 PM

check your calipers, axles, pinch bolts also. is it possible the "clunk" is comming from the rear?

Kamloops · 07-25-2008, 02:53 PM

I just put the bike on the centre stand, zap strapped the front brake down and pulled the front wheel back and forth. The sound is coming from the wheel and seems to be from the clutch side. Near the caliper or wheel bearing. Everything is tight.

NO things are not right.

The clunk has to be found and eliminated.

Check the wheel bearings. Are you absolutley certain it is not the steering head bearings.

Kamloops · 07-25-2008, 03:36 PM

Certain it is not the steering head bearings. it is coming from down near the wheel hub or caliper on the clutch side of front wheel.

Just got an email from my Local Yamaha dealer. These guys are awesome taking the time to answer my emails. What do you think could this be it?

Mike,

I'm gonna save ya a bit of cash here. I just went over to our showroom
sporty bikes. Sorry no FZ6 but FZ1 and R1 a R6 did the exact same thing as
you described and I'm fairly confident got the same noise. What it is, is
the brake rotors are what is called a full floater type disc. If you look
there are little buttons that hold the disc to the hub carrier what is
happening is with the load of the brakes being applied the disc is moving
on these buttons. Not Yamahas but on certain exotics you can actually grab
the disc and move it about two mils. This is normal, THEY use this
technology 'cause the components are thinner than automotive and it's one of
the tricks to keep the disc from warping. ( heat generated under heavy
braking is intense... enough for a burn to blister if touched ).
Hope this quells that uneasy feeling.

Ever since coming back from my ride down in Southern California, I have noticed a clunk whenever I hit a bump from my front end. Not sure if it's the same noise or feeling that Kamloops has, but I can feel and sometimes hear it coming up through my front forks and handlebars. I can't duplicate it from a standstill, I need to be moving and hit a bump. As everyone has mentioned, I checked all the bolts, brake calipers, steering bolt, etc. Seems everything is tight. But I did notice I was missing a bolt or screw that helps hold one side of the front fender. But I can't imagine that the noise/clunk would be coming from the front fender, I mean that it seems my entire front suspension is loose or broken. I'm wondering if it's the front wheel. Sometimes when I'm riding I'm wondering if my front wheel is going to come off. Something ain't right, that's for sure and I've been taking it relatively easy most of the time.
