Re: Yamaha FZ 25 Owners Reviews and Experiences







Actually I used my cousin's 2010 Apache RTR 160 for a long time which has a digital speedometer & it showed all the numbers (0,1,2,3,4), even a UG4 Pulsar 150 did the same. I think it's Yamaha specific that our speedometers jump from 0 to 5 kmph & back from 5 to 0 kmph.

Re: Yamaha FZ 25 Owners Reviews and Experiences

Hello folks. I've been facing the following issues since about 20 days now:
1. Sluggish acceleration in low RPMs. The gears seem to have become taller. Takes more time to upshift through gears and requires more downshifting after braking.
2. Increased harshness at speeds above 100 kph.
3. Whirring/buzzing sound from lower part of engine, around the front sprocket area.
4. Squeaking sound from engine after it is hot.

I have checked my tappets, adjusted my spark plug, done a diagnostic test and also cleaned my injector. Everything seems to be normal.

Odo reading is 18500+ kms.

Re: Yamaha FZ 25 Owners Reviews and Experiences

Well, your issue is really a strange one for sure. maybe try cleaning fuel pump (although i doubt it will help). check clutch plates if they are also fine, shoot an email to Yamaha as the bike is still under warranty. apart from that i don't really know what should be done as i don't have enough experience.

Btw, bike was ever involved in any accident ? or fell down ?

Re: Yamaha FZ 25 Owners Reviews and Experiences

Why don't you change the engine oil to a fully synthetic engine oil, if you're using Yamalube?
I don't know if it voids the warranty, please check with the service technicians before hand.
9/10 times changing engine oil to synthetic does the trick for such issues with no apparent mechanical fault.

Also check this website by Mr.Sagar Sheldekar (Ex-Powerdrift Employee)


He used Motul 7100 10W-50 grade engine oil on our 10W-40 recommended for FZ25.
He claims that the engine runs a lot smoother & cooler due to the higher viscosity of the oil he replaced with.
Any experts on engine oils & manufacturer warranty can way in their opinions.

Thanks & regards,

Re: Yamaha FZ 25 Owners Reviews and Experiences

Bike did fall, twice. Once, it bent the clutch lever. The other time, nothing happened.

Re: Yamaha FZ 25 Owners Reviews and Experiences

I'm already using Motul 7100 10w40. The issue is mechanical.

Re: Yamaha FZ 25 Owners Reviews and Experiences

was the engine running both times ?

Re: Yamaha FZ 25 Owners Reviews and Experiences

Oh ok, I hope you get it solved quickly.

Guys,

On a side note, I'm taking in my bike for first service as it's been a month exactly (560km ODO). I know the service mechanics use Yamalube engine oil as default.
Can we make a request to change the oil to synthetic (by giving them the oil ourselves) or change the oil from a local mechanic?
I wanna stick to fully synthetic from get go.

Thanks & regards,
Narender

Re: Yamaha FZ 25 Owners Reviews and Experiences

Hi I remember you mentioning before about a clutch cable that failed or something like that which happened after a fall. To me your symptoms sound like your clutch plates are worn. Did the SC have an opinion ?

Re: Yamaha FZ 25 Owners Reviews and Experiences

Kindly stick to Semi synthetic oil (even with different brand) atleast till 5k on odo, which ill help in proper engine bedding. After you can opt for fully synthetic.

Re: Yamaha FZ 25 Owners Reviews and Experiences

Not sure why within 560 kms you are taking bike for service. My bike is almost 1 month and 940 kms. I will pass 1000kms within 2 days as my daily running is about 35 kms. I was supposed to take my bike for service last weekend but because of out of city travel and all the kms were not reached. You need to note the recommended oil for FZ25 from Yamaha is Yamalube fully synthetic 10W40. See below. This is from Yamaha website.

Hi guys,
I need some advise here. As stated in earlier post my bike is 940 kms and in next couple of days it will be due for first service. I am going for Yamalube Sporty Premium as dont want any risk in initial period. As I have seen with my bike for past 1 month (940 kms) - the first 100 kms were very rough. The gear shift was hard as rock and used to hurt my toes.


Untill 500 kms the things were little smooth. Gear shift (up and down) improved a lot. Down shift is still little hard. I use 90W gear oil for chain lube for 300 kms. Post lube the gear shift is very smooth. In about 200 - 250 kms its hard again. Having said this, I see constant need for clean and lube of chain.


The headlight shakes crazy and its irritating in night time on bad roads. I am having this checked.


IMPORTANT: Recently I see the rev range reduced and kind of limited to 5000 unless I want to go very rough on bike. 99% times I dont go beyond 4000 - 4500 revs but sometimes i see the bike gets very rough and rev is about or above 5000. I am attributing this to engine oil and expect this corrected after service.


When I ride for more than 30-40 mins in Pune heat (I usually travel to office by 12:30PM) the engine seems to be different as compared to when I ride in the morning or night. I think the 42 deg. cel. heat is killing the integrity of Yamalube quickly and there could be need for XW50 oil in summer (X should be less than or equal to 10).


Please let me know what else I need to check with service team for first service.

Re: Yamaha FZ 25 Owners Reviews and Experiences


It hasn't, I have a couple of videos to try show the noise.





I personally think this is ABS being too intrusive, I could be wrong though. Also, if any one can advice which service centre in Gurgaon is the best with properly trained mechanics for the FZ 25, that would be great.

Somehow the video isnt coming up in my post

Re: Yamaha FZ 25 Owners Reviews and Experiences

Hi everyone. I got around to working on overhauling my rear brakes this week. I changed the caliper piston seals and the master cylinder kit. As they don't just sell the seals for the master cylinder. Welcome surprise was even after 2 years and 24000kms in dusty environment, the fluid was in good shape. The front brake fluid was very dirty. I feel the tolerances on the Nissin are so much more precise that it doesn't allow dirt to get in easily.

Taking apart the master cylinder correctly needs a 2mm drift punch and good wrenches. Would be difficult without good tools. It was not a need as the seals were in good shape. The front cylinder seals whereas had become hard. But since I was anyway doing the rest, did this also.

Used half bottle Motul fluid Rs 202 (405 full)
Caliper seal kit 3JD-25803-50 Rs 182
Master cylinder kit B97-F5808-00 Rs 403

Extra because during an earlier company service they misplaced them and I failed to notice. These usually don't go although the service manual recommends changing them for every pad change. SC doesn't change them.

Shim, Caliper 5XT-25827-00 x2 Rs 674 (Rs 337 each)
Support, Pad 3SP-25919-51 Rs 484

All the parts are made in Japan and they are costlier than the fronts equivalent.

Re: Yamaha FZ 25 Owners Reviews and Experiences

Ok, thank you for the tip. Appreciated.

Sorry, I thought it is either 1000 km or 30 days. It is 60 days. Thank you for making me check the manual for clarification.
Actually I have a trip planned from Hyderabad (My hometown) to Coorg via Bangalore. Which in total is a 1700 km trip. I will have to get it serviced in Bangalore as my ODO will reach 1000 km by that distance.

Re: Yamaha FZ 25 Owners Reviews and Experiences

Hi regarding your chain situation, spray lube like Motul lasts in dry for 700-1000km approx for me. Yes bit time consuming. The entire sprocket kit is around 2100. So have to balance how smooth you want it all the time vs lube cost vs time spent lubing vs chain life/cost. Gear shift smoothness also related to clutch lever play kept as tight as safely possible.

You can check with keeping the tank cap open and riding. If the engine is performing smoothly after, then it's related to the emission control or pressure valve on the fuel pump. If parked in sun for a while also sometimes engine won't start and you need to open the fuel cap. It's an irritation but learnt to keep more than half tank petrol usually.
