Yamaha FZ Engine oil drain bolt thread on engine stripped

Hi I own a 2014 model Yamaha FZ16.

Last weekend after I got my bike serviced, I noticed a slight oil leak near the Engine oil drain bolt.
I told mechanic about it yesterday and he tried to tighten it. In this process he stripped the threads on my Engine.

The bolt is loose and not sitting rigidly in its position.He did a temporary fix by using some kind of glue and a plastic wrap around tape used by plumbers to seal leaking water taps. I feel it may fall off somewhere while riding once engine gets heated up.

Can someone please guide me where and How i can get it fixed?

Mechanic was telling me he will get it fixed in a lathe shop by re-threading and will use oversize bolt but it takes 3-4 days to get it done from some lathe machine guy.
Already 3 years back during my second service itself in authorized SVC they re-threaded it and used oversize bolts to fix leak.The problem is back again.

Please suggest me a good mechanic or a place where I can get it fixed in Bangalore.I'm planning to ride it very slow till it gets fixed

Pic: it looks something like this picture in the below link.



I badly need some quick suggestion on this.Please reply.

Ray's tuned in first block koramangala is a good place. The owner is knowledgeable and friendly, and has some good staff. If you are nearby, I would suggest taking it there to get an opinion.

Re: Yamaha FZ-16/ FZ-S

What does a headlamp relay do? Will it brighten the current 35 35 bulb? Or will it enable me to use a 55 60 bulb? Please enlighten me...

Re: Yamaha FZ-16/ FZ-S

Mine is running at 3500 kms ! i faced kinda same issue, but from past two weeks, m using shell petrol, and bike feels a lot better and under control. sounds really low even at higher speeds, while using Bharat or Indian oil petrol, it makes heavy sound at higher speeds. May be its just me. m gonna use Motul oil in my 3rd service with shell. hope to get better result. PLUS, m getting average mileage of 48 to 53 km/litre !!

average running speed - 50-60
highest touched - 90km/hr in 0-6 seconds.

and i ride solo all the time and i keep the tyre pressure 28 front - 35 rear

i am badly looking for some one who can guide to change the headlamps, i want to shift to led, without ruining stock assembly ! plug n play sort of led bulb !

also i m looking forward to add a switch for lights, these euro 4 rule is ruining my battery. I dont wanna keep headlamps running all the time. !!

Re: Yamaha FZ-16/ FZ-S

I would like to know if you actually reached 90 in 6 seconds?
Gotta report it for a world record for the fastest accelerating fz16 ever.

PS; just a joke, i feel it must be a typo.

Re: Yamaha FZ-16/ FZ-S

I am using Premium Petrol. Getting mileage of 54+ ( I calculated this for upto 5 fillings randomly and it got somewhere near 54-57)

I had only my 2 services yet. They poured Yamaha Oil at SVC, don't know details.

I added a switch for Headlamp and changed lamp to LED (costed ₹1500).

Can u elobaorate Shell Petrol?

Re: Yamaha FZ-16/ FZ-S

petrol from shell petrol pump !! lol

anyway from where did u get the fitting done ? r u from bangalore ?

Re: Yamaha FZ-16/ FZ-S

Ahmedabad. Shell Petrol pump sells different kind of petrol?

Re: Yamaha FZ-16/ FZ-S

Yes absolutely he is right,
Even i faced the same issues with Indian oil petrol,
Recently i switched to Shell petrol, now my bike sounds really better(smooth)

Don't go for power petrol completely because 150cc engines cannot tolerate such high leaded gases.
Go for a mixed one, like 2litres of power petrol with 3litres of normal one.

After doing lots of experiments with this i found this mixture is better.

Re: Yamaha FZ-16/ FZ-S

Thanks I should try it out soon and review here.

Update 18Nov:

I fetched one shell petrol pump. This petrol pumps are way too less than Indian Oil /HP.

Filled 2litre(power)+3litre(normal)
lubed chain with Motul C2.

I cannot see any changes in engine sound until now.

But I shall wait upto to 2 more filling cycles to get shell petrol completely into the system, and then report back.

Planning for putting Motul Engine oil next time.

Re: Yamaha FZ-16/ FZ-S

I was using Motul, there is difference compared to Yamalube. I have noticed in Motul at 6000 RPM it can reach 84kmph where as in Yamalube at 6000 RPM it can reach 87Kmph... So in short even though Yamalube is made by Motul, Yamalube is better in terms of performance and Motul is good for more miles.

FZ-S Halogen to LED Conversion

Trust me, most of us hate that 35w stock halogen that comes with Yamaha FZ-S. It is so bat that you can't see anything when there is someone with high beam on the oncoming lane.

Below is my vlog about how bad the issue is...


I had several conditions in order to upgrade. I do not want to modify the electricals and do not want to overload the battery. So I must stick to the 35w range. Therefore, I got three choices.

1. OSRAM Silverstar
2. HID
3. LED

Since the OSRAM Silverstar was cheaper than the other two I wanna give it a try. It was definitely better than the halogen that came with the bike. Better, but not enough at all. Used it for six months and had enough of it. Time to move onto better ones.

Now, left with the choice between HID and LED. Started to do some research about them. HIDs are bright but kind of sluggish and learnt that it's life reduces with using pass often. But expensive as well.

With the cost involved with HIDs, LEDs looked more attractive and offered better brightness!

Searched for good LEDs in Coimbatore, but none had a decent brightness and looked more of a fancy gimmick. Out of options, looked online and eventually ended with AliExpress.

Fortunately after an extensive research, found that I have to install LED based on the circuit system in the bike (AC/DC). As FZ-S has DC circuit, carefully chose the NAO Motoled 35w DC HS1 LED. It costed me ₹1300 and promised 3000 lumens, that's 4.2 times brighter than the halogen. So placed an order on 9th November and after a "short" delay at the customs, got it on 28th November.

The installation was easy and simple but had to make some modification to the rubber dust cover at the back of the headlight.

Here are the pictures








High beam

Low beam

One thing I noticed was not much difference between high and low, but both are very effective.

So after installation, for the first time enjoyed night riding. Thanks to that LED headlight.

Yamaha FZ-16/ FZ-S

That was a very good written. Loved reading it.
Nice to see such a performance improvement.

Would have helped others, if you could provide AliExpress links to your product.

Also, could you share one more photo, when there’s some oncoming lights. (Especially when some cars comming). I know I am asking a bit more, but it greatly helps others. Thanks a lot for sharing.
