Re: Yamaha FZ-16/ FZ-S




I guess company is specific about the Oil grade as well so I'd suggest you to read the manual carefully and check this with the service center Manager (specially) before changing the Engine oil.


And, I'd suggest you to check the Timing chain tensioner first before changing the Engine oil during the service period. You can also change it yourself just be careful with the bolts while tightening them and don't forget to put a new Gasket while putting it back. You can ask your friend and try to replace the tensioner with his motorcycle if his is working fine.

If the noise is coming from the front wheel's side then I'd suggest you to check the Disk plate and disk pads once. Let someone sit on the rear seat when the bike is on the main stand and try to spin the front wheel and observe from where the noise is exactly coming. and check the front mudguard as well. Hope this helps.

Re: Yamaha FZ-16/ FZ-S

i think manual recommends Yamalube as the brand

bro I followed the break in process very religiously .. I have noted down your suggestion related to timing chain tensioner .. if changing the oil doesn't solve my issue .. i'll see the timing chain tensioner then

for a few months i kept on thinking that the noise is coming from the chain or the rear wheel .. then a few days ago I cleaned and lubed the chain properly but the noise still persisted .. then last week while riding i leaned forward towards the meter console to see if the noise is coming from the front and i felt like it was coming from the front of the bike .. i think maybe the front wheel because when I rev while the bike is stand still and listen to the console .. it doesn't make any sound ..

Re: Yamaha FZ-16/ FZ-S




I'd also suggest you to try using the Yamaha Fully synthetic oil. And try to change the Timing Chain Tensioner as well, I am positive that you would feel the change after changing the Timing Chain Tensioner as it also becomes a culprit in making noise of Timing chain when it gets expanded and when the tensioner does not work properly.


(It usually happens when we don't do the first 1000 Kms break in properly)


From where do you get the whining noise? Front or back? Is it coming from near the tyre area?

Re: Yamaha FZ-16/ FZ-S

Even mine is in 5 yrs warranty. About to complete 1. Warranty isn't void if u use recommended grade. 10w40 in our case. U may verify the same from manual.

Re: Yamaha FZ-16/ FZ-S

okay bro i think i should give yamaha fully synthetic a try.. though personally I would also choose motul but i couldn't risk my warranty at this point.. i had opted for the 5 year warranty plan while buying the bike.. hope switching engine oil reduces the noise to acceptable levels..

Yes bro the SVC people don't agree with me that my bike is making an abnormal noise.. as per them my bike is normal until it breaks down in the middle of the road.. btw where did you complain? the customer care or the consumer complaint portal?

Re: Yamaha FZ-16/ FZ-S

It's very sad ! I too faced many problems in my new hornet, after complaining online they listened to me.

Re: Yamaha FZ-16/ FZ-S

Try filing in a fully synthetic good 10w40 oil. I.e. motul 7100. I use the same on my fzs fi v2. It makes the bike exceptionally smooth. Or if u r skeptical about putting in non Yamaha lubes then in next service opt for R15 engine oil of Yamaha even that should be able to make you feel the difference. Take your pick.

Re: Yamaha FZ-16/ FZ-S

Thanks bro for the suggestion .. i also saw sr motorworlds video.. he upgraded to the motul 300v 15w50 after getting fed up of the noise.. i too am very irritated with the noise.. initially the noise is low but audible.. but as soon as the engine gets heated it gets very pronounced.. there seems to be no issue with the performance though but the noises don't seem normal to me .. when i met the engineer he said we will need to open the part which is making the noise i.e. the part above the engine.. he said it is his friendly advice not to open those parts as the bike is new.. my issue is since this is a new bike why does it require opening up of such critical parts which usually don't need any tinkering.. this is the reason i am thinking of sending them a legal notice because i dont want my new bike to be opened.. if i persist them to fix.. they will say okay we'll repair your bike.. and open the engine.. i already visited the SVC like 8 to 10 times for the 3 services I have done.. Yamaha also doesn't seem to be serious about my issues.. once a mechanic in the SVC said your bike sounds normal.. and made me listen to another fz which i think was there for its 1st or 2nd service.. when he revved.. it felt like it was also making the same kirr kirr noise from the same area.. but i didnt ride it.. just revved stand still.. not sure what is wrong with my bike.. really disappointed with yamaha and their after sales service

Re: Yamaha FZ-16/ FZ-S

Similar problem was reported by sr motoworld YouTube channel, he used motul 20w 50 synthetic oil, but i advice you not to use 50 grade oil, compare with similar aged fz and show to the svc as a proof!

Re: Yamaha FZ-16/ FZ-S

Thanks for the reply bro .. am using the Yamaha recommended Optima prime 10w40 .. this one:-


what do you think? is the engine oil the culprit?

Re: Yamaha FZ-16/ FZ-S

Which engine oil u using. Of its stock Yamaha oil. Well it isn't up to mark.

Re: Yamaha FZ-16/ FZ-S

Guys I am having various kinds of noises in my 2018 fzs which has done only 1430kms.

1. There is a kirr kirr or maybe tarr tarr kind of noise from around the right hand side of the bike. Feels like coming from the area above the engine. Not sure what it is called but I think from where it sucks air. First I thought this was tappet noise so I got it adjusted during my 3rd service. But the noise is still there and it is very audible and irritating. I showed this to the SVC many times and they say this is normal. This wasn't there when my bike was new. At around 1000kms this noise started and it gets worse when the bike gets heated. I even showed this to the Yamaha engineer and he said it is timing chain or I am not sure cam shaft noise and we'll have to open that part and fix. He said since your bike is performing fine, there is no need to do this. But I get very irritated when I ride as it doesn't feel normal to me. This type of noise comes from very old bikes.
2. There is a whining noise from the bike when it reaches 45kmph. First I thought this might be chain noise. So I cleaned and lubed the chain but the noise seems to have increased.

I have done all the services on time and these issues started after the first service. I have complained many times to the SVC and even wrote emails and called Yamaha customer care. They just say visit the SVC or schedule a meeting with the engineer. But everytime I go there they just say this is normal and all is in your head. I feel like I am riding an old 1lac kms done bike everytime I take my bike out.

Guys I want your opinion and expertise since you have experience with the bike. I am thinking of taking legal action against Yamaha and their SVC as I am tired of complaining them again and again and I didn't pay for this.

Re: Yamaha FZ-16/ FZ-S


Standard Tyre pressure mentioned on the bike sticker itself is 28psi(front) and 33(rear). you are over inflating the tyre leading to decreased surface contact of the tyres with the road. this could be the cause for degraded power transfer.

Re: Yamaha FZ-16/ FZ-S

Well I don't have my FZ s anymore but I can say that it's generally a good idea to stick to stock type and size, tell us what, get a correct size used tyre from tyre shop fitted to your bike n see if that solves the problem, u may save some cash if that's the case. If not, you may have to get a new alloy wheel. Still a good idea to check for leaks in tyre itself and air valve

Happy riding

Re: Yamaha FZ-16/ FZ-S

Hey there...need ur help

Serious issue:. my 2012 Fzs' rear alloy wheel is leaking air from its corner..(somewhere between alloy and tyre)
I tried to fix it by gas heating and repairing its shape but still the issue exists.. the shape of alloy is now seems to be perfect. I think some issue is with tyre as it is 120/80 17 bias ply tyre not radial. ( I know it is wrong profile but i was not aware at the time of installation) ..
So changing tyre to its genuine profile would solve my problem OR not???

I think tyre is not tightly fitted or something else.
I am unable to ride my bike as it leaks air everyday and it's really frustrating to fill air everytime before riding.

I searched about tyre construction as bias ply and radial tyre are far different in construction. Bias ply tyres have stiffer side wall... So maybe stiffer sidewall pressurising the alloy wheel's side wall and causing trouble. This is only my perception about this issue.

Help me guys. I want genuine solution.
