Re: Yamaha FZ 25 Owners Reviews and Experiences

It's been a hectic 10 days with almost 1600 km on the saddle. Last weekend, my company had an outing in Sakleshpur. I was intending to drive down initially in my car, but at the last minute thought why not take the FZ25 instead. I had a great time on the Hassan highway, it is so smooth that without realizing it, I was hitting consistent speeds of 95-100 with a lot of performance still on tap. The next day, instead of heading back to Bangalore, I decided to explore the area and went over to the Charmady Ghat and returned back via Belur.

I had already planned a trip to Ooty this week, so I decided to give it for service at the Yamaha dealership. After the service, the engine was even smoother than before. I set out on Thursday via Mysore stopping at Masinagudi to watch some ace cyclists climb up Kalhatty ghat as part of the Tour of Nilgiris cycling event. I spent the next day riding near Ooty, visiting Manjoor, Thaishola, Kinnakurai, Avalance and Emerald Lakes. I had seen the hairpins leading to Geddai and Canada Power House so decided to take that route to Coimbatore the next day. Unfortunately, it was raining throughout and the road was not very good and so I didn't enjoy it as much as I would have. I stopped over at Coimbatore overnight and took the highway back to Bangalore.

I just feel that this bike is perfect for me. It is most at ease cruising around 90 kmph, anything more and the engine is not as smooth as I would like. Plus I dont feel confident enough in my capabilities as a rider to handle speeds higher than 90 kmph on a sustained basis, so this just suits me fine. The riding position is just perfect and if required, I can get into a really level aero tuck to reduce the wind resistance. The seat has decent support and it is only at the end of a long hard day of riding that I feel the effects, especially around the back of my thighs. I went through some roads where there were no roads to speak of and the FZ25 handled all that with aplomb.

No more long trips planned for the near future, but with this bike, who knows what is in store!

Re: Yamaha FZ 25 Owners Reviews and Experiences

Rev the bike till red line in each gear , the pistons need to open up , once they open up it should touch 125 easily and depending on road conditions , wind , your weight , tyre pressure , chain slack, it willl do more , I have personally reached 132 as max speed i am 90kgs, thinner guys in our group manage 140+ , Hope that helps

Re: Yamaha FZ 25 Owners Reviews and Experiences

Thanks for the reply. I am 62 kg only! But i have never even once redlined the engine so far in this 4500kms.. I have tried but felt it is too much for the engine to take it! The vibration are too much if I go beyond 8k rpm..
Anyhow I will try to do a redline on each gear..

Re: Yamaha FZ 25 Owners Reviews and Experiences

Got this sweet beast delivered last week. Completed my first 150 kms yesterday and the experience so far has been great.
As it is the break in period, the rpms are limited to 4500. The machine achieves 60 something on 5th gear at 4500 rpms. Will try to explore greater rpms once 500 kms are done.

Till now, the bike always feels hungry and ready to do more. Just a small twist in any gear is enough to make that overtake. The ride is smooth and the sound is amazing. There is no additional noise and even the gear box is smooth till now.

The only problem faced is that the headlamp and display unit wobble a good deal at 45kmph + speeds or even on rough patches.

Re: Yamaha FZ 25 Owners Reviews and Experiences

slight movement is there in the headlight if it is happening a lot show it to the service center and get it tightened mine was also a bit loose when i picked it up from the showroom

Re: Yamaha FZ 25 Owners Reviews and Experiences

The wind blast is a problem. I have Fazer windshield visor and it is not effective. Saw the Pulsar AS200 visor is fitted by many. Anyone using this visor here? Is it effective against wind? Also, how difficult is it to fix it, especially side clamps.

Lluvia visor is very expensive man! AS200 visor costs ₹450 only.

Re: Yamaha FZ 25 Owners Reviews and Experiences

Wobbling of the display unit is also normal?

Re: Yamaha FZ 25 Owners Reviews and Experiences

You can reduce Headlight wobble to some extent by using 2 extra washers in headlight mount. by default the mounting has a lot of freeplay.
look at these pictures where you need to use those washers.



i hope it helps.

Re: Yamaha FZ 25 Owners Reviews and Experiences

To resolve coin rattling noise from engine, today I had given my FZ25 to a Yamaha service station of main dealer some 36kms from my place (Aluva Vijay Auto). The works manager checked and verified the coin rattling noise by revving up to 4k rpm when the bike is stationary. They somehow reduced the noise and returned bike by evening. He is not telling much except that cam chain tensioner was adjusted. They also re-tightened plate breather bolts. The works manager is telling that this noise is present in all FZ25, some have higher noise levels.

He is saying reliability is not affected. But, he said, if I need further resolution regarding this noise, engine head needs to be removed to check the condition of valves, valve stem, rocker arms etc etc. I don't want to do that.

So @Experts here: Why adjust cam chain tensioner to reduce this noise in only 11000kms?

Re: Yamaha FZ 25 Owners Reviews and Experiences

There's no way you can get coin rattling noise at idle or below 4k rpm. the noise you were getting was tappet noise which can be reduced by reducing valve clearances.
they most likely reduced it and reset the tensioner too even if it wasn't required ( it done as required there's no too low/high mileage period for this afaik) . nothing to worry about just ask them what are the clearance values they have set otherwise too tight values will give you troubles later.

no point in opening engine head, there's no fix for actual coin rattling sound that comes around 4-5k rpm. have recently met a fz25 owner who has done 71k kms on this bike. coin rattling sound is present on his bike as well( along with tappet noise). and apart from regular service only thing he changed are - both tyres, chain set, clutch cable and brake pads. no performance issues on his bike. this just further proves that noise is harmless.

Re: Yamaha FZ 25 Owners Reviews and Experiences

I know tappet noise and coin rattle noise. Adjusted valve clearance few times already. Tappet noise is not the issue. Idle is a wrong word, I used in previous post, it should be read as revved up to 5k rpm, when stationary. That Idle word made the confusion. When I tried to record the coin rattle it is not recorded correctly (in reality the kir kir sound is really loud). It is not tappet noise. I had posted about the coin rattling noise earlier also, in this thread.

Coin rattling noise comes at 4k rpm. He checked at by revving to the 4-5k rpm when stationary. I should also tell that the coin rattle noise has increased only after opening the side cover as part of recall job. It is audible even when stationary revving up rpm, albeit more prominent when you ride at 4-5k. Timing chain tensioner adjustment and plate breather bolts glued and tightened again. This has some effect in reducing the coin rattle noise.

Re: Yamaha FZ 25 Owners Reviews and Experiences

display does not wobble , only hedlight on rough patches

Re: Yamaha FZ 25 Owners Reviews and Experiences

This is very reassuring for the brand. Curious to see if they launch a bs6 version and if they have done anything about this rattling issue on it. This is a dream bike for me with the kind of low end torque it's got. The above is a factor that is keeping me confused.

Re: Yamaha FZ 25 Owners Reviews and Experiences

well the noise is irritating for sure (i like it tho) but if you need more proof if it's harmful or not, just look at these bikes which are having same engine as our FZ25-

1. XT250 from 2008 to 2019 also called Serow 250 in Japan.
2. Fazer 250 (Brazil), currently on 3rd generation which is similar to what we have here.

Both of those have this coin rattling noise coming from balancer mechanism @4-6k rpm. and people have done 70-80k miles (110-128k kms) on their bikes without engine/ performance issues.(source- old posts in xt225 forums) this engine is in production since 2008, and in those 11 years it has gained -

1. oil cooling.
2. Fuel injection (Brazilian fazer can run on ethanol as well).
3. 3-5ps power and 3-4nm torque increase.
4. intake and exhaust port tweaks.

That means Yamaha has constantly improved this engine over time, what remained is coin rattling noise, if it was actually an issue they would have fixed it in those 11 years. the fact is, if engine isn't reliable it cannot survive for 11 years in different countries in different bikes through different emission norms.

i don't think Bs6 version will see any fix to this, but there might be some other upgrades as its been 3 years since the launch which is enough for version 2 makeover.

Re: Yamaha FZ 25 Owners Reviews and Experiences

Resetting timing chain tensioner did not work. The coin rattle noise returned as earlier after a short highway ride. I had a talk with the service manager and he says should leave the bike for 2 days to open the head to check. I think I should not do that. Meanwhile, they adjusted the valve clearances which may be why I face the low end grunt reduced but the top speed remains. The mileage (FE) also has gone for a toss. It is giving 26-32kmpl in city conditions.

What can be done? Is it the wrong valve clearance affecting the bike performance?
