If the SVC is near enough you can ride very slowly there and demand that they drain the engine oil completely and refill it in front of you!! Also make sure they check the bike after that to know if anything else is causing the heating issue.

Although riding more would lead to further heating and damaging the engine but if you want to fight with the SVC then its a different matter.

You can fill up oil yourself at home.

You can try Motul engine oil instead of Yamahalube. Go for Motul 3000 4T Plus 20W40 mineral oil. I would suggest you stick with mineral oil now and change to Semi-synthetic or Synthetic oil on your next service.

Low engine oil is probably causing your engine to overheat. Get it topped up at the earliest!!
Also as a precaution get your bike checked by your local mechanic.

Cheers!

Great that you are knowing important things at an early stage of your new bike. Buy Motul 4T 20w40 mineral oil and then top it up and see that then level touches near then maximum. Please keep an eye on the engine oil level @ every 100kms of your ride.

Engine heating might be normal and if you are still in doubts then take the babe on empty stretch and rip her to the maximum and see if it goes beyond 100 or 105 without too much struggle. Check the mileage and see if it isn't too low or too high.

To check oil in a bike, the bike must be on center stand and engine stopped for at least 15 minutes..If the reading is still less at lower mark,then just add either the Yamalube 20w40 or Motul 3000 20w40. till the level comes up to the max mark.
Engine heating could be due to the Mechanics setting the Air Fuel Ratio to lean(less fuel ,and more Air) at the time of service..If rats chew into inlet pipe or the Air Filter also the same effect will be there....Please do check if the Chain is tight or not lubricated, and if the Front and back brakes are free and both wheels rotate easily....the front Disc will have little resistance like all disc braked bikes do,but should be easy to rotate..

Hi,

Sorry was travelling constantly so couldn't be online. Anyways, What mileage settings were changed? Did they change the AFR settings of the carburetor during 1st service or else they only reduced the idling speed to a lower no. then the usual. As far as i know those guys, they don't mess around with the AFR settings unless you have asked them to tune it for more mileage post your 40 kmpl figure observation and feedback to them.

How were you calculating mileage before you went for the tune up if i may ask? Was it tank full to reserve and then second tank full to reserve method which has been discussed long time back on this thread or was it just filling in 3-4 ltrs and then calculating it?? The FE figure will obviously change if you have accelerated harder or gone higher speeds. Go to the SVC, tell them that you are noticing that the engine is leaning out so tell them to tune the engine to stoich mixture. Easiest way to check it like it has been mentioned many times is checking the condition of the spark plug.

Rough vibrations? Please explain what do you mean by that? What engine oil was put in? did they use Yamalube or Motul Mineral 20W 40 as i have repeatedly mentioned on this thread? Rough vibrations can be associated with the lean.. as a result the engine may be starving of correct AFR. Check if the engine is also heating up.

Please remember they will tune it according to your feedback. So i will not immediately point fingers at them. Anyways, if you are looking for more mileage, change your riding style or else in near future opt for Pulsars or some other brand known for mileage . Jokes apart, it has been extensively discussed here that FZ/Fazers are not known for their mileage.

Hope this clears your doubts.

PSR JI: you are an expert determining lean tuning. If possible please help out this gentlemen how to get the tuning right.

Cheers,

You freely admit to having no idea about engines yet offer advice about them If someone follows your advice and melts a engine, will you pay to get it repaired?
You frequently tell people to rip their bikes, then check if you are running lean....It should be the other way around, However I'll leave it at that. Though I will tell you I will be laughing the hardest when oneday you follow your own advice and loose a engine.
Instead of just learning off a forum, how about you do your own research, learn for your self, get your hands dirty etc. Pull something off your bike, clean it and put it back on. Make a DIY guide or something.

These are air cooled engines. They are supposed to get hot. I don't know of any engine both water or air cooled that you can touch (Unless its running methanol)

Hi Owners,

Yamaha is conducting Mega Camp @ Khadaki Cantonment Board Ground, Pune on 13th & 14th Oct from 10:00am till 5:00pm.
Check more details at your dealers. I just received SMS. No more details.

I haven't spoken which I never knew. Anyways let moderator decide who is what. I have some other works to do not to get my hands dirty for no reason. Don't just drag things and make so complicated that my advice will get someone's engine melted. No problem man I know what I'm doing. I'll be ripping my bike to the end as I usually did to my earlier bikes and people around me know very well how I made stones (old used and thrashed not well maintained bikes) to jewels (get back in perfect condition). For that I have nice mechanics and I don't need to make my hands dirty and with the option 'Plug and Pray'. For me it's other way around Pay the money and Plug and Play Hard.

Once again I tell I don't want to imitate a barber with a comb and a scissor in my hands.

If you have good knowledge then keep spreading but not poking. I also seen you twist my advice from different posts and make it for your own reason to blame me. I haven't given any advice which never clicked. I have my own group of people who very well know about fz-16 not only this forum but also beside me.


Finally I'll leave this matter to moderators and if they find my wrong then surely I'll be the first one to keep quiet.

Dont start over again
I seriously wish that moderators display a disclaimer something like this on every page of the forum (read it carefully):

Thanks for the reply Brad, i do have a very good friend(sales) where i booked my bike, but i have seen people misusing the bikes of others forefront there during my visits. And the online reviews about the dealer for service is too bad and so i took my bike to another service center which holds some decent reviews. Now i am thinking of purchasing the complete toolkit to repair my bike on my own, that will be the perfect remedy for this

Well i am an old school guy so i believe that the work should happen in my presence or else at a visible distance.. Anyways, How many kms have you done since the last service?? Keep the oil topped up whenever needed. If you feel that the engine oil is low then top it up with the same grade, same brand engine oil from Yamalube.

I personally donot advocate mixing of engine oils when topping up and others may disagree so already putting in a personal disclaimer that is plainly my advice. You are free to follow my way or the highway

Cheers,

Thanks Arijit, nice points, i remember the day they delivered my bike, i noticed the engine overheating that day itself and asked the service manager to have a look, that guy told me that its usual for a new engine and pointed out the smell of the paint which is in the crank case due to overheating and i left the service center as they were closing down for the day keeping in mind that i should come back. Will completely analyze and refill my bike tomorrow and let you know the results

My interpretation of the above advice is to give a bike with a (possible) overheating (due to AF since you said to check the mileage) issue a good hard rip. So what if something breaks during that course of action?
Wouldn't it be wiser to check and correct the problem before a hard ride?

I've come across your type Manu in the past, those who pay others to do work on their vehicles, freely dispense advice (more often than not the wrong and possibly dangerous) and live in their own little world thinking how great they are. Even after I did you a favor broke down how I look at a engine and modifying them, you still had ZERO idea about what I was talking about, yet you can give advice on how people can repair and tune their bikes.

I'll tell you something, There is no "praying" on my vehicles. I am guessing you are taking a poke at my engine.
Every step is a deliberate calculated step. I'll happily be riding and driving along knowing I can repair my own gear whereas you will always be having to call up your servants to help you stand up everytime you fall.

My inbox is always open mate. Feel free to use up some of that storage

Again don't get controversial. Don't say things which I have never meant. I never considered mechanics as servants. Please correct that statement and if you think the mechanics are your servants then they might be your servants. Every trade has to be taken with respect. Mechanics get paid for the hard work they do. If a person owns a bike then he must also have money to pour the fuel and pair the repair and maintenance costs. It's better for a foreigner to have good knowledge of our culture before making statements which we feel as rubbish and aggressive and you feel as casual.

@ Vimal_hbk..like Shv18 said follow the directives..FZ is not meant for High Fuel Efficiency..ie., of 50+ and above, and is a good VFM package....To set your Air Fuel Ratio ,take it to the ASC and ask him to adjust it as per Yamaha's directive...Most Japanese Bike manufacturers train their ASC mechanics on the bike they sell, and so the Service head will be aware of it. anything above45+ in a FZ under sane riding condition will lead to engine heating and knocking,under hard acceleration..If you need to know the relationship between the AFR setting and Exhaust gas pollutant levels, here is a graph which will help...Tune for Carbon monoxide(CO) in the region of 1.5 to 2 which will give good power ,FE and less pollution...

@ Shv18 thanks for the confidence in me and I hope someday I live up to it...

Thank you PSR,
From your points, i have to check these things
1, Engine Oil level
2, Air Fuel Mixture ratio: What i hear is that the stock carb settings should not be altered for the first service as per YAMAHA, but looks like the mechanics altered them, i will
inquire how far they had gone with that.
Then again setting them back to stock mode is again a pain with the service center mechanics
3, Need to check the inlet tubes, airfilter

Will keep you posted about the progress...


Nice piece of info, Will some one explain them in detail

Thanks Jonah,
i gained this little knowledge through reading these forums and all is to take a nice care of my bike, your suggestion to rip the bike is fine, but before that i have to make sure everything is right and set proper, eagerly waiting to take my LOTS beyond 100.. But it should be after second service, what do you think?

Maddy, i completely agree, air cooled engines tend to get hot, my first bike was a YAMAHA RX100 and i still remember how much heat it generate.
But i started to worry after a normal ride which covered just 2kms, i felt the hotness on my legs and stopped, confused
And now i am trying to sort things out, now from the replies that pitched in from the fellow Xbhpians i can zero in on two things:
Engine Oil Level + AFR, The service guys might have altered the stock carb might be a cause, i may need to fix that

Someone please share some idea on how to set Proper Air Fuel ratio on the Carburetor, some detailed description with images will help..
