1. 90 grade oil for regular use. 140 grade oil for high speed cruising.

2. After completing free servicing, use shell advance ultra 10w 40 or ZIC fully synthetic 10w 40 oil.

3. 3M dashboard polish or Motomax shiner (works on both glossy and mat finish but makes matt surface glossy !)

Hey [MENTION=98329]#bpk[/MENTION] and others

I just completed my 20k service. I changed the oil at svc itself and I assume they've put Yamalube. My riding is 90% in the city. Are there any other oils that are better than Yamalube for FZ25? If yes, is there any issue in filling such oils or is it safe to stick to what Yamaha recommends?

Cheers!

Re: Yamaha FZ 25 Owners Reviews and Experiences

U dont have to assume,it is yamalube only,do you face any sort of problems with yamalube?

Re: Yamaha FZ 25 Owners Reviews and Experiences

I don't have any issues neither with the oil nor with the bike, touchwood. As it's been 3 years of ownership, I was just curious to change the oil, hoping the synthetic ones from Shell might be better than Yamalubes. It's more of a want than need sort of thing. What are your thoughts? Should I leave the current oil as it is performing just fine or should I go ahead and change? If change, any recommendations?

Cheers!

Re: Yamaha FZ 25 Owners Reviews and Experiences

Bro if u dont have any niggles then y to change and use some fancy engine oils,keep it simple as u have done till now,use yama lube and keep changing oil in periods between 2000 km to 2500 kms, and do check waether they are realy using yama lube sporty premium or optima,recommended grade for oil is 10w40.

Re: Yamaha FZ 25 Owners Reviews and Experiences

Hi, Yamalube will do just fine.

If you want to try other oils, Motul 7100 10w50 is the best one, you even get a 1.5L pack.

At city speeds (assuming 30-80kmph) though, there's no major difference. At higher speeds (90-120) and higher ambient temperatures, Motul performs better.
I assume you have read my posts about having to set valve clearances frequently. Others don't have any issue, some people just tested valve clearance values to see which one fits their bike.

You don't need to worry, as mine is a one off case. I have ridden many other FZs, and they all perform the same (mine is completely different due to this problem). I rode my bike somewhat hard when tappets were tight and continued using the bike in that state, which probably caused something to go wrong.

Just remember one thing, make sure the SVC doesn't touch the valve clearances upto atleast 7-8k kms on the odometer. It only needs adjustment if you hear tappet noise (not coin rattling, coin rattling only comes between 5-6k RPM) when the engine is cold.

Re: Yamaha FZ 25 Owners Reviews and Experiences

Hey guys, even I had the confusion whether to go for 10w-40 or 10w-50, and then I saw this video: https://youtu.be/ASAdkJydBFU

Here is some part of the reply to the pinned comment on this video:
"A 0w20 will flow better colder than a 0w30. You will generally find the Pour Point to be lower and the viscosity at -40F/-40C (if given) to be lower (flow better). As well, you will also generally find a higher base weight to have better high temp performance, so a 10w50 with stay a little thicker hotter than a 5w50 would. There's very little data on this aspect though, no real specs, and only some graph data floating around drawing more extended curves vs temp."

"Two things to note, generally speaking. Thin oil flows high volume. High volume flow means great cooling. Thick oil offers higher protection from metal on metal contact. At the same time, the engine design and clearances between parts defines flow rate and oil pressure. As was pointed out in the video, you can go too thin and loose oil pressure. You may need a higher performance oil pump to compensate. There is a balance in between protection and cooling that oil must do. If you go too thick, you may find that the flow volume is not there, and you may get heat build up in parts of the motor due to low flow and lack of oil collecting and evacuating that heat away. I have not seem much for data on this stuff personally, so I can't comment on specifics. Just understand that some of the recommendation of the oil viscosity is based on the balance of the two aspects. It's just a very fuzzy area for consumers because there is very little test data. Most of the knowledge seems stuck at the manufacturers."

Kerosene can damage the O Ring sealing and the lubrication within it. Continued usage of kerosene may not be good for the chain itslef. For cleaning, it's always better to use a chain cleaner. Even WD40 contains kerosene. So choose a cleaner without kerosene.

Re: Yamaha FZ 25 Owners Reviews and Experiences

Kerosene/wd40 doesn't damage o ring. proof . no need to waste money on cleaning spray. either use wd40 alone or gear oil for lube. both are overall cheaper than cleaner+lube spray combo.

Re: Yamaha FZ 25 Owners Reviews and Experiences

People all over world are useing kerosene for cleaning thier bikes chains,so it does tell something about kerosene,how good it is.many manufacturers tell in thier manuals to use kerosene for cleaning chains,its an tried and tested method all over.so dont bother spending your hard earned money on those fancy cleaners.

And bro afaik complete chain set of pulsar 220 cost about 1600rs,nd those chain cleaners nd lube set combo cost minimum 7 t0 800 alone,so i would like to replace my chain set better then spending so much money on those fancy cleaners n lubes.

Re: Yamaha FZ 25 Owners Reviews and Experiences

Bro,still did not you get a buyer for your as200?

Re: Yamaha FZ 25 Owners Reviews and Experiences

i never had as200,

Re: Yamaha FZ 25 Owners Reviews and Experiences

K,my mistake bro.

Re: Yamaha FZ 25 Owners Reviews and Experiences

Yes,
I was confusing tappet noice with coin rattling and somehow thought that pretty much every fz25 needs frequent valve clearence readjustments since coin rattling is present on pretty much every bike .
