Cheerz!!

The AFR may not be changed, but there might some blockage in the carb valves or jets.. This might prove all the problems.. Shitty hickups

ruining the joy of riding..

ANS: That doesn't mean that you won't have debris in your air filter or any other part. You need to ensure that in the service centre they thoroughly check it.

* Dirty fuel or water contamination due to exposure with rain. DO you ride you bike a lot on reserve? then gum and dirt might have blocked the fuel lines.
> I never run on reserve for long distances. I know the ill effects, so avoid it. I can rule out fuel adulteration, since i fill from a single Company run pump no matter what.\
ANS: Dirty fuel is a very much possibility even from a reputed petrol pump. During monsoon, water may percolate inside the tank and may contaminate the fuel stored in that. SO your bike may be fed with 10% water and rest fuel. It is better to drain that fuel completely and refill the tank with fresh fuel and see if the problem still persists.

* The carburettor needs urgent attention and clean up along with the jets being thoroughly cleaned.
> What all is to be done and checked? Can you share some info please.
ANS: The whole carburettor needs to be disassembled and using carburettor cleaner spray everything cleaned out and then re installed. The Diaphragm and the valve slide needs to be checked. Also the jets needs to be cleaned using the carburettor cleaner spray.

* Check the fuel filter. It is the same contraption holding the fuel knob which can be turned from OFF to ON and Reserve. If clogged then you may face this issue.
> Is it DIY thing?
ANS: Nope the SVC has to check it.

* Check the ignition cable going to the spark plug, see if it has come off loose. Take it out and re-attach it. You can do it by yourself at home less than 30 seconds job.
> That is the first thing i did as soon as i felt the jerks. Still the issue was there.
ANS: The spark plug needs to checked and if the ignition cable is attached properly then it is not the culprit.

This is all i can think of.. sorry going for a "Wolverine" show hence, a quick write up.

> I personally did not like the movie

(need some break from too much of tech knowledge

)

ANS: That's OK i was just doing timepass

Cheerz!!

The rain water does seep in from the tank. But, the rains are lashing since long time now. So, i am scratching my head in this matter. Also, when you press the clutch, was the RPM reducing? I noticed this quite a few times today.
ANS: Rain water does more damage then one can imagine, if the fuel is contaminated with water then the water will settle down the tank being heavier thus your bike is being fed more water instead of fuel. Its like you being in a swimming pool and instead of coming up for air you get to breath in some water.. you know what will be the result.. you will be coughing your guts out.. Check the tank.

Cheerz!!

the whole carb is to be opened and jets looked into for any type of blockage.. the mech cleans it in petrol.. blows into the jets to clean them..
the valves need to be checked for any type of damage..
i don't know much about it, but have seen the mech do it when i used to get my HH ambition serviced..
ANS: Blowing into jets will do nothing. The carburettor cleaner spray has to be used to get rid of the minute gum formations.

ya, there is always a decrease in rpm when the clutch is pressed..
when the bike is started for the first time in the day, the rpm is way below 1000.. and only after a min or so it gets to around 1500rpm..and while stopping at red-lights, its the same sometimes..
as i didn't got the time to visit a mech. to get the carb checked and cleaned, i think this prob will stay by my side..

ANS: If the rpm is fluctuating then that is a sign of wrongly tuned AFR... The RPMs once the engine heats up will remain static or will slightly increase by a few hundred rpms.. if it keep on going up and down something is not right with the fuelling.

Off lately, even my bike starts at RPM less than 1k and it stalls if i don't throttle it. This was not the case initially. Even after setting the idle screw to a spcific limit, the RPM hovers up and down. If the problem resurfaces again, i will have to visit the SVC.

Cheerz!!

ANS: Clearly a carburettor issue either tuning or the carb needs to be cleaned.

Hi All

Can somebody tell me yamaha recommended valve clearances for FZ engines ?

nadz11.ns : RPM fluctuations can be due to leaner AFR mixture. Do have a look at what spark plug looks like.

ANS: Inlet/Intake : 0.08 mm and exhaust valve 0.12 mm . One has to ensure that the camsaft is set at 0' and also that the valve adjustments are only done when the engine is cold.. or else the nos. will go haywire as the valves by properties of metal expand and contract.

Hope this clears your doubts...

Cheers,

Well i have never seen anyone clean the carb with any type of spray.. Will visit the svc in the weekend and get it cleaned there.. Matbe they might use it..

As for the AFR, mine is little lean.. Not much though.. But lean mixture should give me higher mileage, but i'm getting only 33-35 km/L

its been this forma very long time now.. Sometimes only 30-31 km/L..
I mostly ride in the speed range 65-70km/h.. I know what rash n hard riding is, and i don't do it..

still..

Re: Yamaha FZ-16/ FZ-S

[MENTION=32641]shv18[/MENTION]... Thanks for the reply. I will check the spark plug and post a pic here to get your and other member views. Also, how to drain the fuel? I will drain the fuel and check for any water contamination. If so, i will refill with fresh fuel and check for the problem again.
[MENTION=60608]nadz11.ns[/MENTION]... If you are running on lean mixture, the engine is suffering a lot. It is not advisable to run the bike on lean mixture.

Cheerz!!

I know this.. I just git to know about me running lean a couple of days back.. I had also posted about it with pics in the other thread.. Will get everything right during the weekend..

as for draining the fuel, put the fuel know on OFF and take the pipe out from the knob.. You would be needing another piece of pipe to be able to collect the drained fuel.. And then place the know on reserve till att the fuel comes out..

Yamaha Fazer Headlight Upgrade ! Kindly Advise....

Hi ! I just purchased a Yamaha Fazer 3 months ago. I am extremely unsatisfied with the stock headlight illumination at night, even after getting focus adjustment. As both the headlights cannot be switched on simultaneously as it would lead to battery issues. I was thinking of upgrading 35w stock halogens with 35w Philips Xtremevision or 35w Osram Nightbreaker. Where can I find the above mentioned bulbs in Mumbai/Navi Mumbai? How to improve lighting without doing any changes to the internal wiring?

Re: Yamaha FZ-16/ FZ-S

I am from Pune. My FZ-S was brought in May 2011. It moves me about 25 kms, both ways combined, to office , Monday to Fridays. Weekend use is variable. It has endured rides in all hours of the day, two plus years of pothole riddled shabby roads, about 12 months of those with added rains, about 18000 kilometers on the ODO, and three major accidents till date. (fortunately, I was not on it in each case, although I have had a few close shaves). Nothing could stop it.

Only thing that stops it is the bloody rear tire

.

It first got around 5-6 punctures at around 6700-6800 kms. One was so catastrophic that it had to be filled with a mushroom patch. The next was a couple of punctures on the 8500 kms mark. After that, the problem started cropping it's head again at the 17K mark. The leak is very slow, or I'm guessing the puncture guys are not able to find it.

Is it time to replace ?

Regards,
Aditya

You change the things when they start giving you troubles..
change the tyre and enjoy the 'potholled' ride

i also had to change the tyre at exactly same duration.. A puncture so bad that it couldn't be fixed.
also stick to the stock tyre.. Its really good in all conditions..
ride safe..

My first set of tyres lasted 30k km, but the second set have already had more than 20 punctures within last 2000km. the bike's odo is almost 40k

Help me to upgrade components for Yamaha Fazer 150

Hi All,

I am new to XBHP, I have Yamaha Fazer 150 which is almost 4 years old. I intended to upgrade some of its components, I need your expertise on finding the right products.

First and foremost its time to change tyres

1 Tyres
Are stock tyres of fazer /fz16 are highly prone to punctures and do not provide good grip in wet conditions. But there aren't any other options available in 140/70 R17 tyres. So is it ok to go for 140/70 R17 tyres from other manufacturers what are the advantages and disadvantages of 140/70 over 140/60 tyres. Please suggest me a stable pair of Tyres. I occasionally go for touring and every day city commuting is around 25 kms on average. I stay in Bangalore so roads are not guaranteed of their condition.

2 Spark Plug and Air filter
When I have asked in the Panache Yamaha Show room, they said they will not install K&N air filter and Iridium spark plug as they are not standard. Are they are any issues by installing these. If they are no complaints or issues with installing them, Please let me know where can I get K&N air filter installed in Bangalore.
Shall I go with NGK or Bosch or iridium spark plugs and where can I get them in Bangalore.

3 Battery
One reason I wanted to upgrade battery is I wanted to install projectors as lamps. So Battery up-gradation is not necessary, but If there is an really awesome battery available for Fazer I would really like to change to.

4. Head Lamps
Another problem I am facing is night driving, I have calibrated my head lamps good enough but still I am not very comfortable driving at night. So please suggest me powerful and stable lamps set for Fazer 150. I am interested in installing projectors but afraid that it will drain the battery since my bike has no kick rod.

Are there any other upgrades necessary for a bike which is 4 years old

. I am open for suggestions.

Thanks for your valuable time

20 punctures

. Replace the tyre. Are you riding with low air pressure? How often you check the tyre pressure?

Cheerz!!

No. actually the tyres were fine till they run about 6000km, but suddenly started deflating frequently without any punctures. due to deflation and the pressure getting low, later came the punctures. after about 10 punctures or so, I went to the svc and they told me to go to the tyre shop. I went to the shop where i bought the tyre from. they inspected the tyre and said the punctures were due to low pressure. even after rectifying all the punctures there was slight leakage and it was from the rim walls. there was some dust and gravel trapped in between the tyre and rim which was causing the leakage. they told it was a common problem here. the tyres are fine.
