Liveware Problem Posted January 27, 2017 Share Posted January 27, 2017 Hello again!I've noticed today a very distinct whine on acceleration - it increases as you open the throttle, then dies off when you close it.Any guesses as to what part of the bike is/soon will be knackered?

rennie Posted January 27, 2017 Share Posted January 27, 2017 are you sure it's the engine and not the gearbox?chain too tight? Quote Link to comment Share on other sites More sharing options...
Liveware Problem Posted January 27, 2017 Author Share Posted January 27, 2017 No I'm not sure! I do need to check the chain though, should start with that, thanks Quote Link to comment Share on other sites More sharing options...
Guest Posted January 27, 2017 Share Posted January 27, 2017 Does it continue with the clutch pulled in? Quote Link to comment Share on other sites More sharing options...
iangaryprice Posted January 27, 2017 Share Posted January 27, 2017 Make sure chain is not too tight - they can often get tight due to stiff links during bad weather.If in doubt slacken 1/2 turn of the adjusters and test ride. Quote Link to comment Share on other sites More sharing options...
Liveware Problem Posted January 27, 2017 Author Share Posted January 27, 2017 Does it continue with the clutch pulled in? It does yes, seems to be linked to the throttle. Quote Link to comment Share on other sites More sharing options...
rennie Posted January 27, 2017 Share Posted January 27, 2017 remember that we can't hear/see it! Chain too tight will make gearbox whine,chain/wheel misaligned will make gearbox whine,front sprocket crudded up/dirty will make gearbox whine.I'd deffo be looking at chain first Quote Link to comment Share on other sites More sharing options...

eastanglianbiker Posted January 27, 2017 Share Posted January 27, 2017 ignition key..............................makes the rider whine when he cant find the whine..............................joking.............................got o agree with the others check chain first and also tyre pressures Quote Link to comment Share on other sites More sharing options...
Liveware Problem Posted January 27, 2017 Author Share Posted January 27, 2017 Sorry I haven't been clear at all The noise is there whenever you open the throttle, and I think at idle too though less noticeable. So it can't be the chain etc. as it happens even at a standstill in neutral... It increases in pitch the more the throttle is open.It sounds like this r1, video in post 7 (well the whine, not the engine ) :http://www.r1-forum.com/forums/104-04-06-r1-mechanical-help/300349-05-r1-high-pitch-whirring-whining-noise-problem.html#/topics/300349?page=1&_k=qmxkte Quote Link to comment Share on other sites More sharing options...
rennie Posted January 28, 2017 Share Posted January 28, 2017 ok if it happens at standstill it's not the chain! (That wasn't clear! )alternator/generator bearings? I typed that before I read above link!don't think ybr has cooling fan so I could be right Quote Link to comment Share on other sites More sharing options...
Skimblet Posted January 30, 2017 Share Posted January 30, 2017 Is it an EFI model?Mine does this when getting to the high end of revs before changing gear, when I change up the whine goes, the noise appears to be coming from the fuel tank area, so I have assumed it is somehow connected to the fuel pump in some way Quote Link to comment Share on other sites More sharing options...
Chrissb6 Posted January 30, 2017 Share Posted January 30, 2017 Hi, l would stop right there, you've identified that its coming from inside the engine, and your coming across that you not to mechanical minded. Don't start it again until you have got someone with you who knows his way around a motorbike. You could be doing untold damage to the engine - gearbox which if you identify and repair quickly could save you a lot of time, heart ache and money.

eastanglianbiker Posted January 30, 2017 Share Posted January 30, 2017 as the yamaha engine is known to run out of oil have you checked the oil level at all recently Quote Link to comment Share on other sites More sharing options...
RantMachine Posted January 30, 2017 Share Posted January 30, 2017 as the yamaha engine is known to run out of oil have you checked the oil level at all recentlyCould've sworn I read someone saying that they'd run a YBR without oil and it was fine...Oh wait no, that ended horribly Quote Link to comment Share on other sites More sharing options...
Liveware Problem Posted January 30, 2017 Author Share Posted January 30, 2017 as the yamaha engine is known to run out of oil have you checked the oil level at all recently Funny you should say that..Sometime after I came off the bike I noticed it was leaking oil, I took it in to the garage and they replaced a gasket and put new oil in, however I wonder how long it was leaking oil before I noticed I took it in again last Friday when I noticed the whine, guy said he didn't know what it was but to come back if it got worse.. It has so I'll take it in tomorrow.Who could have guessed a 10 year old bike bought off ebay with no service history might be so problematic?

Westbeef Posted January 31, 2017 Share Posted January 31, 2017 The only solution is to do your DAS and get a bigger bike. Quote Link to comment Share on other sites More sharing options...
Liveware Problem Posted January 31, 2017 Author Share Posted January 31, 2017 The only solution is to do your DAS and get a bigger bike. I plan to book mod 2 for a couple of weeks from now I was hoping to sell the ybr on as a going concern but it's looking increasingly unlikely!

Liveware Problem Posted February 1, 2017 Author Share Posted February 1, 2017 Update: bike was starved of oil (wish I'd noticed the leak earlier)Repair bill: £400 (bike purchased for £695)Not sure it's worthwhile, even with it fixed I won't be able to sell it for much.

RantMachine Posted February 1, 2017 Share Posted February 1, 2017 Jeez! Have they told you what they would actually be doing for that £400?? Plenty of complete engines going on eBay for less... Quote Link to comment Share on other sites More sharing options...

Plenty of complete engines going on eBay for less... He did say, sounded pretty bad.. (I've already forgotten the details) I'm going there after work to speak with them. Not surprising really, no doubt it is virtually wrecked after running without oil, then there's paying for the labour of course. Quote Link to comment Share on other sites More sharing options...
RantMachine Posted February 1, 2017 Share Posted February 1, 2017 Yeah but charging more than a replacement engine is a piss take Quote Link to comment Share on other sites More sharing options...
Liveware Problem Posted February 1, 2017 Author Share Posted February 1, 2017 Yes but have you seen what a pig's ear I made of checking my chain and wheel alignment?Not much chance of me fitting a new engine Quote Link to comment Share on other sites More sharing options...
RantMachine Posted February 1, 2017 Share Posted February 1, 2017 Sounds like learning time, then I didn't know squat when I started out, and now I can rebuild dismantle my Honda into itty bitty pieces and stick it back together again using little more than the toolkit under the seat and a bit of guesswork Quote Link to comment Share on other sites More sharing options...
