2010 XJ6 Diverison Noise

pobber1

Hi,

I'm new to biking (2 weeks in) and loving it so far.
I have a 2010 XJ6 Diversion that's making what I would consider an odd noise.
Having said that I'm a complete green horn so I'm not sure exactly what the bike should sound like.

I notice it mostly when travelling about 40km, I think it's coming from the front end and it's a kind of whirring noise. It's constant and doesn't chance pitch.

I've tried to capture it in this video by pulling the clutch in and coasting -> https://youtu.be/-4zzoeu1zUc

Does this sound normal?

You have stopped accelerating so it's engine braking, completely normal.

Go and accelerate really quickly and do the same agin, you will feel the bike slow down straight away and the noise will be louder.

I.e redline the bike in second gear and let go of the throttle

I get the same noise when travelling at speed though.

I tried to capture it in the video by reducing the engine noise as much as possible.

On the bike it sounds different to me than what's in the video. I guess my position on the bike means my ears pick it up different to the microphone on the GoPro.

Probably all in my head

If you're in Dublin, bring it down to Scotts bikes and ask him to take a spin up the road on it - he'll tell you straight.

Prob aok but get the front wheel in the air and spin it, does it bind, can a noise be heard?
Check wheel bearings by turning bars to lock and grip the wheel opposite sides and try to determine play, any at all means new bearings.

Is it just the chain, might have been adjusted recently and is a tad tight. Check the manual for the correct chain slack, yamaha have some mad slack specifications, there's not many yamis that go by the accepted standard 25mm. My MT09 manual says 5-15mm (nuts!) but other bikes are actually above 25mm.

Will check that this evening, thanks.

So having watched your vid. I assume you're pulling the clutch in going by the rev drop. Not really normal riding conditions to be honest. I presume you don't pull in and hold the clutch when riding along.

I pulled the clutch in to drop the revs and engine noise so that the microphone could pick up the noise from the front end. I don't pull the clutch in like that for normal riding.

The video doesn't really capture what I'm hearing so I'll probably have to get someone more experienced to take the bike for a drive and see what they think.

OK, But if that's the only time you can hear it I'd say its nothing. How far up front are we talking? Have you checked your chain slack?

Sounds like a vibration , like the fairing or the after market screen. You could grab hold of the screen/fairing with one hand to see if it quietens. Doesn't sound right though. Also the chain on the swing arm top rubber can tingle if everything isn't clean, straight, lubed and adjusted.

Nice bikes those are, nothing mental, just dead honest things and still look good!

Here's what I would do:

1 - Check the chain tension, make sure that's as perfect as possible and ensure the back wheel is straight (can be out of alignment when you adjust the chain).
2 - Check the front wheel bearings (get the front wheel in the air, use the centrestand if you have one, then pull and tug at the front wheel as described by someone else earlier. Spin the wheel, it should spin fairly freely. If wheel has play then check wheel bearings, if it doesn't spin right check bearings and check front brake calipers too to ensure they aren't sticking).
3 - Check clutch cable adjustment is correct as per manual.

Take note of what gear this occurs in, or is it all gears?

Finally, probably nothing massive amiss, although a bad wheel bearing or an overly tightened chain can get nasty quickly so make sure it's sorted IF it's that.

Sounds like front wheel but can't be sure. Chain and sprockets were replaced last week.

Is does have an after market Puig screen. I will try grabbing it and see if makes a difference. Thanks.

I will check the bearings. The sound seems to be in all gear but gets louder once I go over 40km. Thanks.
