Hi Guys – time to pick your brains again – sorry it’s a long post.
On Friday whilst riding to work I noticed a slight knocking as I’m riding along. This is a new knock and I have never noticed it before – she makes other bangs and rattles but this is different. A quick check in the car park at work reveals nothing obvious falling off and I forget about it for the day.
In the afternoon I ride home to find it has got more noticeable – maybe as I’m looking for it now but I’m convinced it’s really obvious. All the way home I’m worried about the front sprocket flying off – having had a sprocket issue on this very bike before.
The knock can be felt through your left boot as it rests on the peg, it seems to be regular like a drum beat. It goes (or is masked) when I accelerate but is present when I am either maintaining speed or slowing down. It doesn’t happen in neutral or with the clutch depressed while moving and doesn’t happen when stationary. I have had the bike on its centre stand and seems to do it in all gears so happens also when it not under load.
There is no change in the bikes performance, no smoke and it still sounds the same.
Things I have ruled out – but I’m happy to rule them back in if you think they might be to blame!
+ My imagination – my mechanic uncle has ridden the bike and can feel the same knock.
+ Oil – It has oil in it!
+ Front sprocket about to fly off– we stuck a camera up there and the nut and washer is still tight and exactly where we left it.
+Wheel bearings – both front, back and sprocket carrier bearings were changed about 2500 miles ago when I fitted new tyres.
Having spent the best part of an entire weekend about this time last year trying to find a metallic rattle which sounded terminal only to find it was one of the LED’s in my indicator that had worked loose I thought I would ask the question on here fist….. “What is my noise?”
I have already ordered a new chain, front and rear sprocket for her – the current ones look OK but are a little worn – but not enough to cause this I wouldn’t have thought.
If it helps the bike is a FZS600s in gold, on a 2000 plate and has covered only 56000 miles.
Thanks guys – looking forward to some suggestions…..
