Re: Yamaha FZ-16/ FZ-S

Wow, 12k and my chain hasn't stretch a bit

Re: Yamaha FZ-16/ FZ-S

My bike is at 22K+ on the ODO as well and I'm still running on stock Chain Sprocket kit , never changed so far. My next service is due sometime next month and I'm planning to replace it then. AFAIK , the life of chain sprocket is usually 20K-25K KMS , although one may prolong its life with proper care and timely cleaning / lubrication.

Look for Motul C1 , C2 for cleaning and lubrication ; bit on the expensive side but they are worth every penny.

Re: Yamaha FZ-16/ FZ-S

I own a fzs v2 (2015). I had upgraded my rear tyre to 140/70, since then the rear drum brake efficiency has reduced quite a bit, no matter how much I adjust the rear brake its not the same as before, even I have replaced the old brake shoes but its still the same. I think it is because of the higher profile tyre. Has anyone with the old fz have upgrades to a 140/70 tyre and face the same issue? Is there any way to solve it with aftermarket brake shoes or can brakeshoes of any other model bike be a direct fit to fzs v2 to solve the issue?
And one more issue is that after getting the 140/70 tyre the bike has become tall geared and the pickup has reduced quite a bit which results in frequent gear changes in stop and go traffic. The new tyre (140/70) is 14mm taller than the stock tyre (140/60). My bike has a 41 teeth rear sprocket, can I get the same stock performance by installing a 42 or 43 teeth rear sprocket?

Re: Yamaha FZ-16/ FZ-S

This is the problem with the FZ that the rear brake is spongy and if there is something feedback you get from rear drum, you are lucky. Didn't you stop with front brake? Actually front brake of FZ is one of best brakes in 150cc in India.
You have to see whether 42/43 T rear sprocket P.C.D. (Pitch Circle Dia.) is matching with the older rear sprocket P.C.D.
If not, then you have to rev 1k rpm extra to reach the torque band e.g. 4k-5k in 4th gear & finally 6k in 5th gear, like R15, tall geared motorcycle.

Re: Yamaha FZ-16/ FZ-S



Earlier with the lower profile tyre the rear drum brake was just about ok , at that time I used 60(front)/40(rear) braking, but now the scenario is that the rear brake is quite useless now the ratio has turned out to be 90/10, if I apply the rear brake either it will lock or will provide 10% braking. Ya the front disc is a life savoir it really has good feedback as well as stopping power.

And as far as the gearing is concerned the higher profile tyre is a boon on the highway as the taller gearing keeps the revs low on higher speeds, but its a pain in the city traffic especially in kolkata where I stay , needs frequent gear changes.
I am planning to install the 42 teeth rear sprocket from yamah sz. Hope that its a direct fit.

Re: Yamaha FZ-16/ FZ-S

Before going to Sikkim I short-geared my fazer with 14/41 set-up. After Nathula-Zuluk successfully ridden, I installed 15T front from R15V2 & 40T rear (Stock) from FZ. It was direct fit and cost 100 bucks. Then I went many places like Bolpur twice, frequent Kolaghat Sher-e-punjab. Overall tall-gearing is very good when cruising in HIghway but somehow I felt that the gearing can be better. So, I changed the rear tyre to 140/70 pilot street 5600 bucks. The bike feels sluggish while stop-n-go traffic, but once I get any flyover, the speed crosses 90-95 easily without straining the engine. I have recently done 860+ km massive run from Kolkata to Vizag in 15hrs just for the tall-gearing. Bike felt lots smoother in higher revs. i.e. 6000rpm = 88-90kmph, 7500rpm = 111-113kmph. This set up is now front biased and lacks rear braking. Stops only with the front brake.
Coming to the point, I don't think the SZ rear sprocket will fit because the chains are different on fz and sz. So get checked while buying.

Re: Yamaha FZ-16/ FZ-S

Thanks for the info, will the 42 teeth sprocket from R15 v1 be a direct fit to the fzs v2 or would it be better to go for a 13 teeth front sprocket with the stock 41 teeth rear sprocket combo? Well i am really a noob in calculating gear ratios and all so really confused.
Are you running 140/70 tyre on 15/40 setup? then your gearing must have become really tall

Fz Yamaha oil leak

i have brought second hand bike last week. i gave service and got it back.
Now there is oil leak from the bottom of the bike near the gear pedal.
i dont know whether its a engine oil or some other thing.
kindly suggest something to do next.

thanks

Re: Yamaha FZ-16/ FZ-S

Guys I'm owning a new fzs fi v2.0 , it is giving some grinding noise i feel it is from timing chain, can anyone help me with this and how-to reduce that?

Re: Fz Yamaha oil leak

Visit your service centre again. Sometimes the engine oil drain nut doesn't fit in again after service.

Re: Yamaha FZ-16/ FZ-S

Please don't mind brother, actually there is no info in the web about the PCD of Yamaha FZ/SZ/R15. Even while I was buying before sprocketing 14/41, I kept my fingers crossed and hoped that it wouldn't mismatch. So, you have to buy the sprocket (42T from R15 V1 separately, from indiaspares.in). If it matches then good and if not then olx is the last option.
Yes. Gearing is very tall. In city, I cannot pull in 3rd gear while in 19-20kmph, I have to shift down then, but in Highway, 90 on 6k rpm just [80 on 6k rpm (stock)].

*shifter (not pedal).
anyways, the chain lube from the front sprocket may be gotten warmed up & started passing thru the gear shifter rod. can you show a picture properly?

(Before Morning Start, I mean before starting for the day) Pick a small screw driver flat end, open the left panel under the seat, then remove the cam chain tensioner knob (rubber knob), now insert the screw driver normally i mean straight, try to turn it into clockwise holding with another finger so that the backward spring force of that screw do not get back to initial position, after 2-3 turns it will be locked at a certain position, then tighten it to further 20-30 degrees or more or less, your cam chain is tightened now, then slowly turn the screw anticlockwise to retain back the ping force and when you feel the spring force is returned, slowly turn with the spring force, don't left to rotate the screw with the spring force, after you reached the original position, leave the screw, then put the knob carefully, start the engine & check. There are hell lot of videos in youtube to adjust the cam chain or timing chain. You can follow them too.

Thank u bro but , do we need t do this each n every day......!

Re: Yamaha FZ-16/ FZ-S

Listen brother. I guess the gearbox magnet cover gasket have to be replaced, because the oil is spreading not from the front sprocket cover, it is from the fasteners and the gear shifter shaft. Gasket may cost you about 150/- and 600/- for the Magnet Cover. Please go to a very good service center and tell the mechanic "I am in no hurry, you take time and fix the issue, but please don't let me come to you again."

Not required at all. Periodic tightening in 12-15k km and replacement in 50-60k km. Costs only 320 INR.

Re: Yamaha FZ-16/ FZ-S

thanks saikatbyte.

i have someother problem too am just figuring out the problems in bike so that i can tell the SVC guy the problems.

Now the pickup is not proper. I mean bike struggles to reach even 60. but the initial pick up is asusual.
I changed spark plug as per mechanic.

sorry for asking too many questions. whenever I went to mechanic they simply saying to replace the part with out even looking at.

kindly suggest the problem regarding pick up issue..
