Re: YAMAHA FZ 16 Jerking Issue (carburetor model)

Thanks for the advice. Between when the mechanic tried to adjust the carb air screw, it got broke. Need to replace the carb now [emoji20]

Re: YAMAHA FZ 16 Jerking Issue (carburetor model)

Backfiring from exhaust will not harm engine parts.
Maximum they will charge 500-600 bucks excluding GST :P

Re: YAMAHA FZ 16 Jerking Issue (carburetor model)

Re: YAMAHA FZ 16 Jerking Issue (carburetor model)

It is called Backfiring. Normally backfire occurs when there is some unburnt fuel inside the combustion chamber and ignited by the heat of the chamber.
Remedies:
1. Check Carburetor setting (rich or lean) and adjust the fuel screw (brown screw) by rotating 3 complete counter-clockwise turns or slightly more from the locking point. If you cannot, then don't screw it up, go to Yamaha Authorised Service Center and request the mechanic to adjust it and clean the jets carefully and not in hurry.
2. Check the fuel tank if there is water or not, normally water inside a fuel tank will look like round bubbles just below.
3. Last one. Change the petrol pump. Always opt for company owned pumps than unroof petrol pumps.

Your issue is related to non-adjusted valve clearance or tappet clearance. Did your mechanic adjust valve clearance with filler gauge? In FZ series, the valve clearance is 0.08-0.12mm in Intake & 0.12-0.16mm in Exhaust. Take minimum clearance otherwise there will be noise. And, while doing the clearance make sure your bike piston is in TDC (top dead center) and verify the alignment at the magnet cover (engine cover at left side) whether they are misaligned while adjusting.
To check AFR settings, you see there is any black carbon deposit or white ash like deposit in spark plug, the first cause is for rich AFR and later is for lean AFR. Adjust the carburetor as I said in the above thread.
P.S. Don't wash the carburetor so often, because it is very sophisticated thing in vehicle, any damage can burn more fuel or heat up engine.
BTW, What is lathe work for valve adjustment?

YAMAHA FZ 16 Jerking Issue (carburetor model)

Hi,

I own a YAMAHA fz16 from 2013 and I got the bike as a brand new . I left the bike unattended for 6 months recently as I traveled abroad. When I came back, I found my bike starts jerking at lower gears and even it was getting switched off. I gave the bike for service to a local mechanic near by and checked the following

1) Valve seating adjusted (Lathe work) - Done
2) Carb cleaning - Done
3) Air screw adjustment ( Not able to adjust as the screw has been pasted after previous adjustment, only way is to give it to the lathe and remove the air screw, put a new one and adjust again) - Not Done (Tomorrow I am going to proceed with this)
4) Air filter - Changed
5) Oil Filter - Changed

Mechanic Suggestion:
3rd point

I still face the same problem again the bike jerks at lower gears and switches off every now and then. I would like to know the exact reason/ things which we would need to check. I would say there were no problem with my bike experienced with respect to the engine till now and this problem looks to be weird .

yamaha fazer 150 2012 model Exhaust pop on deceleration

the story is simple but bit complicated,

bought a second hand fazer 2012 model 3 days back
50k+ km finished ,looks neat
while test driving noticed the popping sound from exhaust while deceleration, consulted a local mechanic though, said will be minor thing air filter related can be fixed nothing to worry,

apart from this the bike is nice to ride perform well, finally i bought it.
second day given to the local mechanic to fix , regular serivice, oil change oil filter change done,
carb cleaned, spark plug changed, said the sound is reduced and will be fine in few days.

i felt the same fire cracking sound on the way back, only while accelerating bit high and after sudden declaration the sound is coming , some times sound or sometimes a simple burning noise.
carb cleaned, spark plug new, air filter is ok.
now what should i do to rectify this ?
i am thinking of visiting yamaha service centre.
i would like ti know the reason. and is it harmful in any way??
please spread some light ..i am in the middle of nowhere
thanks

Re: Yamaha FZ-16/ FZ-S

Okay I shall do the required. Thanks for the input.

Re: Yamaha FZ-16/ FZ-S

1. Check the rubber-gasket on the oil filter cap. Most likely its not been tightened properly or the rubber gasket is leaking. Replace that if need.

2. Looks like the drain bolt has been cross-threaded or over-tightened. In any case check the crankcase for cracks. If the leak is minor then you can use plumbing tape around the drain bolt to temporarily seal the leak.

Re: Yamaha FZ-16/ FZ-S

I am facing this issue everytime I change oil with oil filter. I went to ASC and they cleaned and reapplied the O-ring. But still I see oily surface around following parts:.


1.below oil filter bracket.
2. somewhere near to oil drain bolt - it seems oil leaking from the engine body itself.

Is there any proper solution to this?

Re: Yamaha FZ-16/ FZ-S

Won't affect acceleration much. The tyre itself will form a curved profile, it won't look as wide as it actually is.

Re: Yamaha FZ-16/ FZ-S

Tire would fit, but acceleration would go for a toss in favor of better handling.

Re: Yamaha FZ-16/ FZ-S

hello guys,
i have 2009 fz 16,
i also have a spare tyre with me mrf revz c1
150/60 would the tyre fit or give any problems during cornering or so if i fit this in my bike.

Re: Yamaha FZ-16/ FZ-S

Spent 13k on engine overhaul, but my bike still eating engine oil. The best part is that yamaha refused to give warranty even after 1.5 k kms only because i use motul 7100.

Re: Squealing sound coming from engine

brother just check the chain sprocket and rear wheel damper
