KTM Duke's Rear View Mirrors fitted on my Fz
Many saying they look good.

Re: Yamaha FZ-16/ FZ-S

Yup, it is very easy. My bro's handle was almost broken. No clue about the cost. Get it done at the SVC.

Cheerz!!

Re: Yamaha FZ-16/ FZ-S

Guys, facing a strange problem. My bike starts with a single kick, i give choke and idle it for sometime before moving on. Now, since yesterday i am facing strange issue. The idle RPM just does not set in properly, it fluctuates a lot. Sometimes it goes below 1k RPM and sometimes it suddenly jumps upto 1500 RPM (happens even of the engine is hot) . Also, while riding i feel jerks and have to press the clutch to keep jerks at bay. But, it resurfaces again after riding some distance. I tried changing the setting of idle screw, but is of no help. As said above, the RPM keeps fluctuating even after setting the idle screw. Oil changed recently, sufficient fuel, cleaned the spark plug wire, tyre pressure perfect.

@nadz.. You were facing the RPM issues recently. Any recommendations for the same? I guess its the same with me also.
[MENTION=32641]shv18[/MENTION].. Can you please help me out.

Re: Yamaha FZ-16/ FZ-S

All signs lead to the carburettor. The possibilities i can think of:

* The air filter or the air intake path might be clogged with dust, dirst or obstructed with something.
* 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.
* The carburettor needs urgent attention and clean up along with the jets being thoroughly cleaned.
* 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.
* 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.

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

Cheers,

Re: Yamaha FZ-16/ FZ-S

its the same with me man rpm fluctuation.. jerky ride.. happened a lottt last week, but for the last couple of days, its really fine now.. didn't do anything..
maybe as @shv18 has mentioned, it might be due to altered fuel.. i take this the case for me as i tanked up from a distant unknown pump for the first time.. started having this problem..
and then i filled at my usual pump and the problem is not bothering me much.. but still there..
apart from that, didn't had time to get the carb cleaned.. i know after almost 20k, it much be clogged or worst damaged..
as the rains slash us most of the time.. a few drops of water with dust particles from the tank surface can go into the tank and then to carb, which could block the minute jet holes..
do get the carb cleaned and so will i.. hopefully the problem will be resolved.

> 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.

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.

Cheerz!!

Re: Yamaha FZ-16/ FZ-S

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..

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..

Re: Yamaha FZ-16/ FZ-S

Thanks for the reply.

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!!

Re: Yamaha FZ-16/ FZ-S

ditto.. same with me.. and this won't go away on its own.. we need to show the bike to a mechanic (or svc)
yesterday i kept the rpm at 2000, and it came down till 1200-1300 and its there till now..

Re: Yamaha FZ-16/ FZ-S

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.

Re: Yamaha FZ-16/ FZ-S

hello Heisenburg (Meth Master)
don't know about the valve clearance..

its slightly on the leaner side.. checked yesterday.. will get the bike fully checked/serviced by the weekend..

Re: Yamaha FZ-16/ FZ-S

I take it as compliment !

@all : Please help me with valve clearances

EDIT : Got valve clearances from some other thread.

The Inlet is 0.08 to 0.12mm.
Exhaust is 0.12 to 0.16mm.

Re: Yamaha FZ-16/ FZ-S

you can get any information from xBhp.. every little detail has been discussed.. it just gets lost in the stack.. needs a little bit of searching..

Re: Yamaha FZ-16/ FZ-S

Damn!! This surely is a carb problem. The AFR has changed. But, how can the AFR change suddenly?

Cheerz!!

IMO, these figures are almost correct. Have read about this in a forum.
