Yamaha FZ-16/ FZ-S

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 ??

Once engine oil is used (few kms), it starts to loose it's viscosity by time, even if the oil is not used very much (few kms), just check the oil color and viscosity after an interval. The time duration of loosing viscosity of an used oil is though not known to me. Maybe the experts can help, or you can also check the engine oil thread.

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!!

Thanks for the knowledge..
i didn't rode much in the last couple of months.. So was concerned.. Now its good.. Would change it soon..

Guys, the disc brake is feeling spongy. It is not as effective as it use to be. What can be the reason? Anyway to rectify the same?

Most probably air has gone into the brake lines. You have to bleed the brakes. There are some DIYs to do this in the DIY section.
Try them. However if you are not a 100% confident of doing it then best take it to a mechanic.

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

the holes in your carb's jets are very small. Small pieces of dirt that gets past the filter will block up the small holes. Over a few tanks more and more of these holes will block up, The result is you need to open the throttle more to keep the same speed, Thus more throttle = more air therefore more fuel.

I had opened up my (stock) fuel filter outer and much to my suprise...there was nothing in there.....I got a clear inline filter within a few hrs after.

How good is HP Racer 4 20W40, 20W50 engine oil?

Re: Yamaha FZ-16/ FZ-S

Hey Guys
Since yesterday, when i drive above 30KM or go in 3rd gear, my bike starts giving sounds from back.
Day before it didnt start, so I put it in reserve, started it, and then switched to ON. It went fine, and i drove over water once. So what might be the issue?
Is it the chain that needs lubrication? Or what?

Check out in the Engine Oil forum. That will be of great help to you

What kind of sound?

Are you on low fuel? If so, there are chances that you might have run into reserve.

When was the last time you had done chain lube? Check if the chain is dry or not. If it is dry, do the lubing.

No I am not on low fuel.. Tank has nearly 8L Of fuel now.
Chain, well I tried touching and was very little greasy. I think its the chain that needs lubrication. Do we need to lube the chain once a week or what?

How many kms on the odo? If the problem persits, get the fuel line cleaned.

Chain lube is to be done once in 300-350kms to keep the chain in good condition.

Re: Yamaha FZ-16/ FZ-S

Yeah. I am going to service center tomorrow.. I think it is a problem with fuel line.
Its just 100KM On Odo.

Ok, so the bike is very new. It should have a kick. Every morning, the best practice is to kick-start the bike. Did you try the electric start when starting the bike?

Re: Yamaha FZ-16/ FZ-S

My Bike handle bar (or steering) is making a sound ( tak-tak, or expanding, contracting sound),its not frequent though, while I brake hard at low speeds, is it normal? and I think this is somehow related to the wobble I am facing. Any insights?
Thanks

The sound which you have mentioned is coming form the cone assembly due to play. Nothing to do with breaks. Apart from sound, you will feel it too. In seated condition, press the front break & force the front wheel forward, you will experience the same. If it is coming ocassionaly then it's ok, but if it coming to often while riding over the speed breakers or through pot holes, show it to SVC, you might will have to change the cone assembly (bearing & races). Do not over tight the locking nut or else it will damage the bearing & races which might result in staeering lock.
I faced the same issue, tried greasing, tightening eventually replaced the bearings & races. Now the sound & vibs are very much gone.

You can surely just get the ffe, u'll need to rejet the carb since the resulting fuel air mixture will lean out due to the ffe.
A well designe ffe will result in better performance throughout, though there'll be a small trade off with the torque in the lower range.

You do not have to rejet the carb only for FFE. You can tune the stock carb if you have to. I have installed the new FFE with the Simota stock replacement filter & Joel himself told me that there is no need to rejet the carb. The stock carb can be tuned to compenset for the extra air. But if you use the conical filter then you will have to rejet the carb.

about front break pads.. there will be scratch marks on disc.. you will notice them, look closely..

If you have scratch marks on the disc, then you might have damaged the disc already & the changeover should have happened before.
You will need to check the grooves on the pad to confirm if it needs to be replaced. Easy to do that, refer to the thread in DIY, it has pictorial description.

Re: Yamaha FZ-16/ FZ-S

Just shine a light down your fueltank next time you have your cap open, see how much sediment is actually in there.
.

Mik, you should have added a rider over here; just don't light a matchstick to see how much sediment is there. :-D... It actually happen with a friend of mine, with very predictable results... :-D

It kinda reminds me of a joke employment advert.

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..

I'd disagree with what you said there (I put it in bold)

The fuel tank just gravity feeds or drains into the carbs bowl. Middle left side of the tank when sitting on the bike.
When the floats drop down (because the carb has fed the fuel to the engine) they open a valve that allows more fuel to fill the bowl, raising the float and then when the float is high enough it closes the valve.
It works in same way a flushing toilet refills itself.

Now when your tank is empty meaning no more fuel drains into the bowl then the remaining fuel is used until the fuel runs out, then the engine stops.
You can recreate this by switching your fuel petcock into the off position and running the engine until it runs out of fuel.
I do this when I need to open my carb and don't want to have fuel going everywhere.
Everyday hundreds of thousands of people around the world experience this same phenomenon. How many people have you seen pushing their bike/car to a petrol station or have stopped on the side of the road after they have run out of petrol?

You won't get a continuous lean mixture by having low fuel in the tank.

Ask a tuner about lean engines and HP. You will be surprised with the results.
