Well to be honest (and cut the SVC guys some slack

) blockage in the air path can also cause the mixture to go rich (because now there is less air and so more fuel for the available air).
Make sure the air filter is not blocked. Once I inadvertently kept my bike documents in front of the air intake under the seat (in my defense it looks like a nice slot to tuck in documents and I was a noob

). My bike was bogging down and unfortunately I ran like this for about 2k kms before its discovery and removal.

Make sure the air filter is clean and the air flow is not blocked anyway. Then you can get your carb checked.
Dont go to the SVC if they hesitate to touch the carb, go to a mechanic and try showing him the spark plug.

Cheers!!

Yea, even i agree that the slot looks fine for keeping documents

. But, from my friends experience (just like yours) i dont keep any documents there. Also, i changed my Air Filter this sunday only. Few pages back i have posted the pic of old vs new filter. Maybe a visit to SVC is on the cards.

Cheerz!!

My Spark Plug ran about 1800kms (after fitting a new one) and it went kaput. Looks like it is a case of fouling. But, i am not able to figure out what can be the cause for same. Can anybody throw some light on the same?
@shv18... your valuable inputs will be appreciated

Hi,

sorry for the late reply.. been travelling. Anyways, the pics indicate spark plug fouling.

A spark plug fouling may occur due to:

* Excessive rich AFR Tune

* Old spark plug being used beyond the recommended change interval

* Oil fouling due to worn out piston rings/ oil leaks

* riding the bike at extremely low speeds and not letting the spark plug reach its optimum operating temperature

* Dud piece being bought and then installed in your bike. If that's the case getting in touch with an NGK official distributor will help you source out a genuine one. Stick with stock spark plug and avoid Iridium nonsense. You can thank me later for saving you 400 bucks later.. :P

These are some of the reasons i can think of behind the early demise of your spark plug. It would be a good idea to get the compression test done in order to gauge the health of the cylinder and the piston and piston rings. If the compression is less than 1200 kilopascals (at sea level) then your piston rings might have worn out.

More details about compression testing has been provided on my FZ 18 thread at pit stop and general biking discussion area.

Cheers,

Thanks Shv for taking out time and replying. The spark plug was bought from Yamaha SVC. So, i guess it will be genuine.

*No oil deposits observed on the plug.

*The one which went kaput was a new one and had ran 1800kms before going bust (bought from Yamaha SVC).

* Bought a new one (from Yamaha SVC) yesterday and this also went kaput

Also, my choke isnt working. Can this be an issue?

Anyways i am visiting SVC today. Lets see what solution can they give me.

Appreciate your help :thumbup:

After the 3rd service of my Yamaha FZS , now my bike engine is really getting hot even if I ride 5 km in 15-20 mins with normal speed 40-55kmph. I can feel the heat vapor in my jeans

while I ride the bike.

My 4th service is coming next week. It might be the issue of Engine oil "YAMAHA LUBE" I am thinking for opting another best Engine OIL.

Can Service center change the Engine Oil from Yamaha lube to any another Or I have to do it myself. They charge me Rs.345 for free service ( YAMAHA 4T 20W-40 SL, 1L(Rs.305) + ELEMENT ASSY,OIL CLEANER (Rs.40) ) Plzz help me out choosing best Engine Oil as I don't know much ..!!!

Also my Bike mileage is been change before it was giving 38-39Km now it is giving 32-33 max.

My bike 3rd service was done from another service center as OKHLA in NEW DELHI, Before my 1st and 2nd service was done in same center (YUSUF SARAI, NEW DELHI)

No other Problems in My Bike as ODO meter is 3200km .

----consecutive posts auto-merged-----

Bhai Same story with me... Earlier my bike was giving 38-39Km after 3rd service Mileage came down 32-33Km per litre .. The Only change I felt was My Bike is not Vibrating after 70km speed.. earlier it was vibrating alot..!!!

Hi bro sad to hear

i have called the service center guys and here was the reply.. They said the reason might be because of tyre pressure, chain lube, chain might be tightened more.. but these are not the problem, as i do check air pressure every two weeks, lube the chain once in 2-3 weeks and chain looks totally fine.. they asked me to get the bike for check last week, but till now i was out of station.. Probably by tomorrow will take to them.. and also my bike produces more vibrations which is pathetic, irritates a lot while i pull off the throttle.. the engine does not flow free at all.. will change the oil when i go.. Please let me know anything else to be checked and also after the service please let me know what do they do for the problem and how the bike feels.. will be waiting for the reply.. thank you so much

Ya, i had done all that. The knowledge has been looked into.. I had also taked to psr ji about this few days back.. But this all requires time to check and use different jets and stay with the one best suited for the bike.. Presently i don't have the luxary of time to do all this.. Not till march.. So maybe after that..

----consecutive posts auto-merged-----

Well i also get mileage in the 30-35 range..
if your mileage has decreased after the service, the mech might have changed the fuel settings.. Check the spark plug for rich mixture..
use synthetic oil if you want a free engine.. Mineral oil start holding it back after only a few humdred kms after service..

Yeah dude will check on the things you mentioned.. thanks for the reply.. will surely change the oil to synthetic.. i understand about the mileage of your bike, but i am worried because it dropped as soon as the service is down and that too by 5-6 kms which is huge for fz..

Mileage does change. It either increases or decreases just after the service. Fill up again and check the average. If things dont change, go to the SVC. When was your last oil change??

Cheerz!!

Hi dude.. yeah i tried checking it thrice.. no change, it just makes me feel sad

during the last service oil was changed.. but you think mileage drop by 5-6 kms is normal ? if its 1-2 kms is fine, but 5-6 i dont think so ?

To be frank, even i get fluctuations in mileage readings. Mileage depends on many factors. How do you check the mileage??

I check Reserve to Reserve.. after it reaches to reserve, i fill it, and check when it reaches reserve..

Have you checked for rice mixture ??
Post a pic of you plug here..
a drop by 4-5kms is not normal..

Hello Guyz,

Had anyone changed the complete wiring kit on FZ and cost please?

Thanks

There is a screw which is used for tuning the air-fuel mixture entering the engine..
if the mech had changed the mixture towards rich (ie. made more fuel to enter the engine) then mileage can come down..
see the pic above that another member has posted.. If the tip is dark like that, then that means the mixture is very rich..

To the best of my knowledge, most likely the two spark plugs you bought from the SVC were dud piece. Worse case scenario, it would be a good idea to also check the state of health of the Ignition coil. Though it is very rare that the coil would go bad so soon.. but still you can get it inspected.

Choke cable might have gone bad. It is quite normal amongst FZs and Fazers. You should replace the choke cable and everything will be fine..

Cheers,

Visited the SVC and cleaned the carb. So, for time being things are looking good.

Guys after that minor accident last week, I changed the brake lever and checked the pads it was about to wear out. So changed them and bleeded the brakes, now they have become really spongy . The mechanic bled them thrice but still it is spongy, what could be the problem? The mechanic told the entire brake assembly is to taken apart and serviced, he said only one of the two pistons is pushing the pads and the other is idle. Could this be fixed without taking the brake assembly apart?

What is the tyre pressure to be maintained in fz

The One reason about Your Bike Vibrating may be its because of the New engine and it may take time according how much you ride bike....!!! My service Center told me to ride the bike as much as u can .. which will free up your engine and other bike parts...!!! He said Vibration will not gone at once,it will fade day by day...
