Re: Yamaha FZ-16/ FZ-S

Is it just me, or does anyone else find oil drops in just 250k's shocking. Irrespective of the speed you ride in, oil drop in such short distance means something somewhere is fishy, I'd suggest its about time you inspect your rings.

Re: Yamaha FZ-16/ FZ-S

guys ...my bike had its 5h servicing.....i changed to yamalube semisynth..... unfortunately i dint find any change in my ride.....i mean quality....people have said the ride becomes smooth...mine is still grunty........is yamalube semi synth crappy quality as mineral??... also the job card showed the oil name as "R15 SEMI SYNTH OIL".... is this correct??? Not a major issue ....just a concern.....

btw i used turtle wax hard shell paste...... and have to say....results are mind blowing (bit of work-out though...).....mine being black cyber green, the black fades with time.....nd this helped in restoring that showroom finish.....

Re: Yamaha FZ-16/ FZ-S

My pleasure

Congrats on your new steed, it looks good

Many things has changed, The rear mudguard, cables, seat length and width, seat cover, grab rails, etc.

Turtle Wax and Formula1 (original) both are equally good, and yes the after effect is very pleasing

Re: Yamaha FZ-16/ FZ-S

Cant comment on the quality of Yamahalube as I havent used it except for the factory oil which came with my ride and that wasn't SS. Been on Motul ever since
But i've heard that Yamahalube is not that good.

And yes the job card is right. Its mentioned as R15 Semi synth oil because R15 comes factory-filled with Yamahalube SS oil.

Cheers!!

Re: Yamaha FZ-16/ FZ-S

When checking my fz-16's mileage, i usually follow Reserve to reserve method..but the readings are constantly irregular..like if it shows 39kmpl once, then the next reading would be 32 or 33, and the next would be 37-38...so i think that this r-r method is also faulty..so i followed a different approach today. First I rode my bike until the last drop in the tank and carburetor is finished. After the bike stopped completely, then i filled 0.66 lit petrol (Random ) and it stopped after 28.5km.So the FE is 43 in city driving..After that I rode with 100ml(I know this is highly faulty) on highway,no brakes,no clutch usage, speeds around 55-60 and it stopped at 5km(so FE should be 50kmpl).
Later I filled 1 lit of petrol and now the bike has gone till 41km..and still didn't stop..its moving perfectly.I expect it to go around another 5km easily.

Any flaws in this regard ??

Re: Yamaha FZ-16/ FZ-S

I personally dislike Yamalube. Was on Yamalube till my 6th service. Gear shifts are smooth only for some kms and then it becomes pain to change the gears.

Cheerz!!

Re: Yamaha FZ-16/ FZ-S

I personally think the engine should never be let run low on fuel.. Its not good in the long run for the engine..
As by running extremely low on fuel, the engine runs dry and this causes excessive heating.. Better keep the fuel level up and look for others ways to check the economy..
as in your case, the economy is very random, so take the average as your economy.. There isn't any way to get 100% accurate results..
also during summers, the economy would drop a bit.. Due to heating, the fuel in the tank would evaporate more..
my knowledge can't be accurate, but don't let the engine go low on fuel on purpose..

Re: Yamaha FZ-16/ FZ-S

Mileage depends on a lot of things. Among them are riding style, tyre pressure, road conditions, traffic conditions, weather conditions, engine condition, load on bike etc. So determining exact mileage is nearly impossible unless are in the controlled environment of a lab.
Hence the best way to approximate mileage is to take a lot of reading by varying each of these conditions individually (Maybe u can add 1KG extra weight and then check mileage ) Since thats not practical, its best to check the mileage for a long time over varying conditions. This is exactly what happens when you do reserve to reserve. For about 400KM your bike runs over varying conditions and then u can calculate your mileage. Do this many times and average the results. This will be a pretty good approximation of your mileage. You are probably getting different readings from reserve to reserve bcos your riding conditions changed. First time you did reserve to reserve maybe you had a good amount of highway riding, but the second time u faced a lot of city traffic. Do this for a few months and average out your results. You will notice that the average doesn't change much (+/- 2kmpl) unless there is a major change in any of the factors listed above.

How you measured gave u a mileage for the conditions at that time of measurement only
If you do the same thing again, chances are that you wont get the same value. Even a small change like a red light which was green last time will cause your reading to vary.

Statistically speaking your sample size is too less to take a reasonable measurement. Thats like saying average height of men in your city is 6 feet because u saw 2 men who were 6 feet tall.

Apologies for the long rant!! Hope this helps!!

Cheers!!

Re: Yamaha FZ-16/ FZ-S

You have just sucked all the crap and dirt from your tank into your fuel lines. I hope the fuel filter can filter out the crap and not end up clogging your carb, Causing you to get less mileage. This experiment can work on a brand new straight out of the factory bike, Not one thats a few months or *gasp* yrs old. Just shine a light down your fueltank next time you have your cap open, see how much sediment is actually in there.


What do you mean by "the engine runs dry"?
Only time you will get excessive heating is if the airflow to the aircooled engine (or radiator) is blocked and lean AF's (amongst other reasons like lack of coolant in radiator/heat exchanger) to increase mileage.

The downside to running your engine on low levels of fuel is what I mentioned above and also with the humidity present in the air, it can help speed up the rusting of the inside of the fuel tank.

Keep the tank topped up to reduce rusting. If you are worried about paying for a full tank then top it up in 1/4 or 1/2 tank fulls.

Re: Yamaha FZ-16/ FZ-S

i meant the exact same thing as you did regarding the lean mixture, just didn't used the right words..
lean mixture would lead to less n less fuel intake and result in engine doing unnecessary work in providing power..

Re: Yamaha FZ-16/ FZ-S

+1

Never run your bike on low fuel. This surely adds lean mixture in to the combustion chamber.

Well, i follow the R-R method to check the avg. This does vary a lot. So, no fool proof method to check the average.

Cheerz!!

Re: Yamaha FZ-16/ FZ-S

As far as i know the best method to check FE is to put in 2-3 lit in an empty tank and then run till 90% fuel is over(its better to leave that 10% so as to be out of other problems mentioned by various friends above). So with these 3 lits one can travel approx 110+ kms easily with varied load and conditions..If we do this 3 to 4 times then we get the average.

Re: Yamaha FZ-16/ FZ-S

SO the dirt should have been filtered by the fuel filter . explain how now i would get less FE? I dont understand

Re: Yamaha FZ-16/ FZ-S

A query..
its mentioned in the service book that the engine oil should be changed after every 3000 kms or 70 days..
i wanted to know if we don't ride the bike much.. How would the engine oil deteriorate ??

Re: Yamaha FZ-16/ FZ-S

The oil starts oxidising when it comes in contact with air. Just like you should not use engine oil which has been kept idle for quite long time.

So, if the running is on higher side, it is advisable to drain the oil at regular intervals or change it once after 70-80 days period if running is on the lesser side. This will help keep the bike in good shape.

Cheerz!!
