Re: Yamaha FZ-16/ FZ-S

Guys, someday's back i had posted a query for my disc brake being spongy and not working as it use to work. Posting a pic for the same. Any views ??? Does it require bleeding or something else??

Also, for chain lubing, can the chain be cleaned with cloth and lubed with EP90 gear oil or have to clean the chain with some solvent??

Cheerz!!

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.

a good explaination..

thanks..
maybe my knowledge regarding the matter was not on target..

i have a similar kinda condition on my disc..
i haven't felt any braking loss of any kind, but would get the pads changed soon..
Senior members could shed a better light on the condition and what to next..

about the chain, wiping with a cloth won't remove the dirt from the chain..
For the oil to work, it needs to be free from such hard dirt.. So it would be much better if you use some solvent to clean the chain and then lube it with oil..

For chain lube use Motul Chain Spray.

Maybe the pressure of the braking fluid in the brake lines isn't right.. That why it is behaving spongy.. I think so..

Ask ur SVC guy if wash ur disc brake with diesel when u give ur bike for servicing.
This has happened to me many times. I have even complained to Yamaha abt this after which the head mechanic of the SVC called me and asked me to bring my bike and get it checked. He told me that the mechanics do this because they use diesel to clean the bike's engine n all. They are not supposed to spray diesel on the disc but they still do it out of carelessness.

That probably is the case. After taking delivery of ur bike from SVC, if u feel the brakes lack bite, ask them for a cotton rag and clean the disc a bit. The ride slowly and carefully home and claen ur disc with a mildly soapy water. This improves the bite although its still will take some time to regain it all as ur pads still have diesel on them.
If you can clean ur pads it'll be good.

Are you sure ur brake feels spongy?? Or is it just lacking bite. Spongy is when u feel the brake lever is being pressed against a soft rubber pad. A well maintained disc brake will make the level feel like its being pressed against a hard surface. Do you feel the sponginess this way? If so then there is probably air in your brake lines. Get it checked or bleed your brakes.

Cheers!!

But if you use the conical filter then you will have to rejet the carb.

Yeah my bad, I meant the same though. You cannot leave the carb in stock settings

Well, in my case i have to pull the lever almost till half way. And yes, it does feel very spongy. After servicing, the lever was tightened. But, the response of braking lacked its bite for sure.

Have read on other forums that, other fellas press the brake lever as hard as they can and tie it with the accelerator lever. They leave this overnight and they have observed good braking response after that. Is this a right way?

Cheerz!!

also is it me or is it impossible to view the brake fluid thru the given glass??....will the sponginess b there if the brake fluid is low??

Someone here suggested using ep 140 or ep 90 gear oils for chain lubrication.

how far are these ok for lubricating o ring chains?

Exercise extreme caution

Dont worry... You are not able to see the fluid because its DOT-4 fuild which is colourless. If you were expecting a dark pink coloured fluid then thats DOT-3 fuild.
The stock bike comes with DOT-4.

As far as I know those gear oils should be alright.

Confirm with the seniors about the same.

Personally have been using Motul for chain lubrication.

Have heard that the OKS chain spray is cheaper.

Been using ep90 gear oil,though recommended is ep140.both are too good.works wonders.just clean the chain before applying. Though I clean it with kerosene and toothbrush...
