Indeed Yamalube is light years better Honda's OEM oil (10W30), losing smoothness by 800 km. CBR means SS, right ??

To be safe stick with W40 or W50. W30 becomes nonexistent when too hot AFAIK

Hi,

Yes the cone set up tightened a bit now & knocking sound is gone..but the steering has become a little stiff..but manageable, will be doing the greasing of the cone bearings soon..as suggested by the technician..
Also somewhere in this thread I posted the issue earlier with the same remedy..

Bent Alloys

guys I need your help on this.

I hit a pothole/bump on Chennai Bypass road .Both of my rims were badly bent.

Took it to a local mechanic and he fixed it for me for around 2k but recommends me to change the Wheels.

I agree thats it mistake to take it to a local mechanic instead of SVC in the first place.

My question is that if now I take the bike to Yamaha SVC and change the Wheels can I claim insurance??

My bike is 7 months old 4k on the ODO and have gone for 3 services.

Please help me guys

yes, you can claim insurance. At what speed did you hit the pothole

wat does SS stand for???? I am referring to Honda CBR 250R...the 250cc bike they launched few months ago....hope u r aware of it



ThanQ for ya input



Rim Bent!!!!! omg m surprised such a thing happened.....cos i know that alloy wheel is very tough.

ya plz tell wat speed were u doing....let it serve as a warning to other FZ users n may they avoid such a situation.

Hi Iceman,
Although I reckon that the "upper" number (viscosity @ 100 deg.) is not as crucial as the "lower" one (viscosity @ 0 deg.) in our regions, I would not recommend to lower the high temperature viscosity: the pressure will be reduced, and your engine not well enough lubricated, resulting eventually (air cooled engines go easily to 150, even 200 deg.) in rupture of the oil film and it's unpleasant consequences.
An oil "weight" of 40 is already quite fluid. Less is for racing bikes built with very small tolerances and whose engine has not been worn. Unless yours is brand new, it will need a thicker oil than 30 if the manufacturer says so.
I want however to attract everybody's attention on the lower number: when the maker says for example "10", it can be 5, or less but not higher or you will face difficult starting and even total lack of lubrication until the engine has warmed up...which may be too late.
These numbers have been carefully worked out by the manufacturer: do NOT improvise, please.

A last correction, Iceman: from 40 to 30 is not plus or minus 10 percent= 20 but 33% of the lower number and 25% of the higher one.

Enjoy your rides

That I know man
SS means semi-synthetic. No way they are gonna use their mineral crap in CBR

Thanks very much for the response abhijit.
That's the solution they generally provide when complain about noise in front fork . It reduces/removes the noise bit it'll be back withing few days or weeks if you are lucky (just as Arnold keeps coming back in Terminator )

It is definitely not normal for a 3 month old bike, unless your riding style is in such a way that it damages the fork. I'd suggest you call up yamaha back office and complain about it.


Yes sir, the first time when I called even I was very surprised to get through them so easily and more surprising was their demeanor, very ready to accept complaints and they see that it gets resolved. Got to know that ASC will be screwed royally for the complaint.

Have to say one thing here, once the complaint is resolved the ASC will ask us to sign a satisfactory note... got to know through back office that we dont have to just sign it, we can mention a comment in the note that we will monitor it for a X months or some period and only then they can confirm with us that we are satisfied.

I happen to have my speedo replaced for the same problem after complaining to the back office, had to complain as the person at ASC said digital speedo is just for show and its not supposed to show exact reading and guess what..... he was ready to put that in writing and provide it to me .
BTW, wrong fuel indication is back in new speedo too, I guess we 'll have to live with it


My update:
Yamaha service engineer called up and asked for the problem with my bike, told him the story again, to check the job cards as I had mentioned the same problem in all services it comes back within a week or two after service is done.
He came with some theories what might be causing the sound and he asked when will I be free and available at the ASC so that he can check the vehicle.
I was adamant, only if he is there I'll come to ASC else there is no point as ASC guys couldn't resolve the issue till now and I don't think, just because you called they will be able to resolve. He promised he'll be there to check the problem in person and resolve it.

Met him after office and we went for a test ride on some bad road and he got the point, the noise was coming even if we use the front break real hard.
He doubts the issue can be with ball bearings, and it can happen with many reasons

1. over tightening the fork (resulting in shape change of balls over a period of time)
2. No proper greasing (which should not happen if the bike is serviced regularly, he specifically pointed to the points mentioned in service manual and guaranteed that all the points will be done by any ASC without fail )

I can only remember these too...sorry

He was mentioning that they are taking very special care of this case as they haven't had any complain on fork noise till now. I was like.... WTF.... a lot of people here at xbhp have it and they are not even aware of this problem?

Will be going there tomorrow for the service as it was bit late. Will update tomorrow on what they find as the problem is.

Hi Khan,

That is what I mentioned above & in my earlier post. When I tightened the cone assly/fork last time the noise was gone completely till I met with an accident. Now also after tightening the noise is gone completely. May be in your case he did not tightened the assly properly.
Also ball bearing loosing shape is very rare there may be normal wear unless the bike is very old or if it is a manufacturing defect. As I mentioned my technician also told me to get the bearing lubricated properly in next service.
Don't drive long with such a knocking noise get it fixed...

nice info , what will happen if we increase the second number ie from 20w40 to 20w50

I haven't signed any satisfactory note here at Hilton svc. But I do remember signing a few at Pearl Yamaha, when I was in Hyderabad. But back then, the bike did not have major issues.
And almost all of us had this tak tak sound issue at some point of time or is going on non-stop.

Nothing much that you can notice but perhaps (?) a couple of clicks lower top speed, (and how can you know that it is not the conditions in which you are driving wich affect your top speed?) but your engine will and increase it's temperature. A balance will then be reached where the increased temperature will fluidize the oil a little more.
Since we are on FZ16 ownership thread here, you will notice that Yamaha recommends one or the other indistinctly.

Ahaaaaa yes....i had completely forgotten that CBR250R has a liquid cooled engine and it can do away with a 10W30 type oil......a big error on my side
and i was not sitting down with Calculator to find the exact 10% tolerance level
m an ENGINEER and i know how others find the number game to be boring....it was just a figure given to state n make understand a layman that the engine can be pushed beyond its current working state

Anyways thanQ for lighting up ma tube-light.....it def shows i didnt give it a full thought n consideration

PS - buddy waiting for u to shed the details on rear disc brake.

Hey guys,
Been riding around on COMPLETE trash mode..shifting gears at 8-8.5k rpm every gear and my bike returned 40kmpl In stock form it would go down to 28kmpl Hope this trend continues

Cheers

did you test the top whack ?
