As you have crossed 1500 kms, now come one rip the bike to the full throttle. See if it's responding well. Keep the full throttle only for few seconds (just as my brother Shvv bhai always says) as I always do and see how is the response. Keep the engine oil till the maximum level. Just see how far it goes. I always check my bike's top speed atleast once in a week in a safe open stretch highway when there isn't too much traffic and that too for few seconds only. As my old mechanic always says if there is good pickup and mileage then there isn't any problem with the vehicle. Anyways you have a year of warranty, I think you don't need to worry about your engine.

Please don't touch the carburettor atleast till 5000 kms, I don't understand how these crap SVC guys altered the stock settings. It's strict orders from Yamaha to SVC guys. If you think that they have done anything with your carburettor then you must tell them to revert back to stock setting immediately.

Even i want my Bike to get repaired in front of me, but you know one thing, entering into an authorized service centre is an offence and nobody encourages it here(atleast where i booked my bike)

India is the land of bribing and sweet talks. Everything can be done by tipping and being nice to the mechanics, sweet talking and PR giri. I got my way through so others can too. If you constantly hover around their head, they will get offended. Rather than being pissed off at a wrong job done, point it out and calmly ask them to help you out.


Cheers,

also one more thing.....yestrday i simulated a riding scenario with my bike was on centre stand (means i accelerated and shifted my gears while on centre stand)......i saw my bike's chain was getting rubbed smwhere at the place where it goes inside the engine and was making sm noise.......does that mean my chain is slacky? or this happens usually??

yes in mumbai kamala yamaha they do it in front of you.. @ SHV18 bhai....did u see the new sewri SVC?...its nice nd pretty gud.....you are now able to see evrythng they do to ur bike....including washing....

Re: Yamaha FZ-16

I agree. Its a good idea to invest in a tool kit for yourself. Nothing to expensive. Just the basics to do your own oil top ups, brake tightening, changing lights,etc.

If you look at the Graph it is self explanatory.The ideal AFR is at 14.7 of air to 1 of fuel, and hence the ratio 14.7:1 as the ideal setting..if you look at the CO level , it is at 1.5 and power is peaking at this mix ratio...It is the CO in exhaust gas that harms us and the environment, and hence should be adjusted for as low as possible, without loosing power and FE.....hence adjusting AFR for exhaust CO of 1.5 % , is the ideal setting..You should warm up the engine before adjusting AFR.
Never run bike in gear on the main stand...it has risks . The noise you heard is of the chain running on the chain sliders on the swing arm...doing it repeatedly will destroy the protective piece and chain will cut into the swing arm pivot and frame..When the bike is being driven this will not happen ,except with a very loose chain.

This article was shared sometime back here.

And I found these steps on a FB page:

Carb tuning for optimal settings.

1. Make sure the bike is properly warmed up i.e rip for 10kms.

2. Put the bike on main stand.

3. Raise idle to the max you can. In my case it was around 6 or 7k.

4. Close the AFR i.e clockwise till it stops, and be gentle. Now idle will drastically drop and keep fluctuating.

5. Open AFR 1/4th a turn at a time and you'll see the Idle starting to rise.

6. Open till you reach a point were the idle stops fluctuating and remains constant.

5. Now open abit more and the idle will drop, so go back gently to the point where idle doesnt drop and doesnt fluctuate.

6. Now set idle back to 1.4~1.5K (1.8K in my case)

7. Done!


Honestly I have never tried them, so please try them at your own discretion.

Will be glad to know and correct myself if anything in the above is wrong.

You still haven't answered my question.. did you do the FE check by filling the tank to the brim and then hitting reserve or else just put in 3-4 ltrs twice and then checked the FE? If that was the case then the FE figure you are getting will not be correct. Secondly, if you are getting 40 kmpl then its absolutely fine. If it drops below that and hits say 35 kmpl then that is a matter of concern which clearly means that the tuning is running rich. I still doubt that they have fiddled with your carb.. as i have been visiting the workshop for over 2 years now and they have never done this to any of the rides unless they have been asked or annoyed to the core by mileage hungry Junta!

Thirdly, if you still continue to ride her at 60 kmph = 4000-4500 rpm.. you will end glazing the sides of the engine cylinder wall, if i have understood Mik's points correctly. Post 500 kms as per the manual, you can take her upto 6000 rpm. and post 1000 kms (replace the engine oil again!!) you are free to rev her. Anyways visit the workshop, tell the head mechanic that you are getting too much mileage and the engine is running lean, as a result of which the engine is starving of fuel. Tell them to open up the spark plug and see the colour.. that will give you a sure shot sign that your engine is running lean. Tell them to make the mixture stoich. Which engine oil was being used?? was it Motul or else Yamalube.. as per the latest reports Yamalube mineral oil is crap!!

I am not able to get it what you mean by engine vibration. Anyways, the vibrations may have increased because of lean tuning. Ask them to check if they have adjusted the chain too tightly or kept it too loose.. that may increase the vibration. Besides that i cannot pinpoint the exact problem without looking at your ride in person. The head mechanic would be your best friend to hep you detect it. Please understand mate that they cannot resolve everything at one go 100% they are human after all. And sometimes the root cause may be as minute as tightening a single bolt. So what i suggest that you visit the workshop at 10:00 am sharp and let the SVC head look at your ride when there is not too much rush at the workshop. They are lightning fast so your problem should get resolved in minutes. Correct tuning and upkeep is a must.

I am still not in Mumbai so haven't had the privilege to check out the new workshop yet nor got the chance to start working on my RC build!


Cheers,

Woww thats awesome, is this type of service available anywhere in Chennai? Any idea Chennai XBHPians...!

Taken Jonah, i will never do anything on the carb

Rightly said, will try to implement this during my future visits to the service centre. Its always possible..

Thats pretty neat and crisp explanation as usual, Thank you PSR

Thats an Idea, even i am longing to know how far my LOTS can do, will update my top speed in this weekend
