My mileage now after the carb cleaning stands at 44kmpl, ride is sport type average 70kmph on highway and rush hour traffic in city. Which is pretty good, but still there is slight misfires.

User @Sudipt24 PM that Yamaha SVC personnel told him that SZ-R air filters were faulty and replaced it free of cost. I had to pay money for the airfilter last service and i was not told of this. Can anyone else confirm this so that I can see if I can indeed get the money back from SVC.

Also yesterday my clutch retension spring, one that's on the exterior right above the clutch box, (spring spray painted in white) got cut. I think they will have to remove entire clutch box to replace the spring, I can still run the bike. But is it imp to replace it immediately?

from discover 135cc to yamaha szr 153cc

how is the pickup to reach 0 - 80km?
I had discover 135cc. In terms of performance will i enjoy any difference..?
pls reply. I m almost ready to buy.

Even I get 44-45 kmpl of mileage with sports type of ride between 60-70 kmph and yes my bike also misfires after I release the the throttle which is acceptable i think, if it misfires during you accelerate then you have to get it checked.

As far as air filter is concerned, I had to change it since first one was 1 and half year old and completely clogged, after air filter change the bike is back to its original shape.

And whats up with faulty air filter? Is it in new batch? or in the old ones?

Cheers!

Yes, I couldn't wait till next service interval with a bad clutch. So while leaving the bike to get the clutch overhauled I confirmed this that its the ones sold in 2011. Also spark plugs too are to be changed in few fz and SZR. They confirmed that the faulty ones will be know by the batch of the Bike chassis number and month. So I was indeed entitled for a new one, but since I have already replaced it.
She will try to deduct that in the next bill if I purchased after the date they got memo to replace faulty ones. But in case I purchased before that, she said I can get one replaced in future whenever there is a next filter change due free of cost.

Hi Prajnyan,

so you went to the SVC and confirmed it.

by the way to which SVC you went? i didnt knew that spark plugs are also to be replaced. is this one also a faulty one?

if you have any info then please tell me so that i can also get it changed.

Yes indeed its at an Yamaha SVC - Bangalore Wheels, Rajajinagar.
I'll get further information from them regarding spark plug change.

By the way sudipt24, you had asked for a good choice of tyres sometime back and I had mentioned against Lalit's above comment that Pilot sporty were poor built for Indian roads.

Guess what? They have now come out with a special reinforced tyre type for India. Not the Korean kind which wear out fast and get punctured frequently.

The exact model number is as below(remember to look out for the exact details coz any other without this would be the regular old model). I don't know price details. I am not currently planning on upgrading tyres. But if you do, please let us know its price and performance without fail.

Front: 2.75 - 17 Pilot Sporty 42P IND F TT
Rear: 100/90 - 17 56P RE-INF Pilot Sporty IND R TT

Does it mean that misfiring occurs due to faulty Spark Plug? Even I hear misfires sometimes, when I shift gear holding clutch, the moment I hold clutch the RPM drops to idle and i hear a misfire but that too very rarely not always.

Earlier when I asked about this occasional misfires the SVC guys told me that the air intake for SZ-R is quite big and not all the air gets mixed with fuel, the additional air comes out when we release the throttle. Not sure how true it is.

Any one can put some light on it?

Michelin Pilot Sporty

Is there any one using Michelin Pilot Sport 100/90 17 56 P TT for rear tyre and 2.75 17 42 P TT for front tyre Are the tyres tubless or with tube, as TT stands for w/ tube, bt many says we can use them both ways.

Thanks a lot Prajnyan,

even my bike misfires too. but not regularly.this happens when the bike is in Higher RPM and suddenly you apply clutch and brake to slow down then there will a sound like the bike has Pharted.

but this happens occasionally.

regarding the tyres which you mentioned any idea where to get them and are they soft compound tires

because the stock tires are also hard compound ones. so even if it runs for 30 -40k KMS the tread will be ok.

therefore buddy can you please tell me the place where to get it and the compound of it. Price hardly matters to me. i don't want any more accidents as i cant see any more scratches on my Bike.

Regarding the small misfire, its common, I have had it in my bike from day1. That happens when there is compression exhaust release gases when at same time you take off from the throttle suddenly then , at times when you dont give throttle but are going down steep gradient you can sometimes feel this too. Just make sure that it doesn't emit a loud thud sound nor should the engine switch off when riding. Then that's called actual misfire and a problem to take care of.

As for above mentioned tyres Yes its a relatively soft compound and gives good grip in rain, but it's not a off road tyre, ment only for city streets. It should last you less than 20k km, I don't know any tyre dealers.

Thanks a lot buddy for the Info.

will check in JC road this weekend if this type of tyre is available now.

if i find any will tell you the price as well.

Guys,

Dont you all think that not having tubeless tyres is a huge minus in Yamaha SZ bikes?

No, I dont think so, the price it comes Yamaha could only fit tubed tyres. The huge minus in tyres is the brand, they could have used any brand other than very hard compound TVS, but they didnt. But yes the current tyres serves its purpose well.

Well, TT stands for TubeType.
They are tubeless tyres that are designed to be used with a tube (inner tube) if fitted to a tube type wheel. You can use regular pilot sport ver. with much soft compound, but they dont last on indian roads well. Say 10k-15k km only and start getting punctured sooner than you think! Plus I am not really sure that our normal alloy wheel rim is sufficient enough to hold the air!

Yes, absolutely, considering an tube type and tubeless is almost same price. But the catch is an TVS tyre+tube pair costs around 3.5K, whereas a tubeless pair sets you back by atleast 5K. So the bike cost escalates by another 2K.

The main thing is this bike is intended for those who travel at speed limit of around 40-60kmph and travel a lot, so in order to give more mileage and tyre life they chose hard compound tyres which are best suited for the bike. Yamaha will think twice before doing any wrong decision, even Pulsar 150, Apache, Hero Ignitor etc comes with TVS tyres(Eurogrip). Seems like company doesn't want to burden ppl much, those who want other tyres would naturally change it!


Sorry Bro, infact when it comes to marketing the pathetic tube type is infact closely priced to any tubeless. But getting a good rubber of tube/tubeless is what's not possible due to cost factor, which I completely agree with you!

One of the problem if they went tubeless would be :
1. Running Life of the tyre (in km) will be less.
2. If there is a puncture and air leaks, mileage and pickup vastly gets affected.
3. Considering where the bike is used in Indian roads, a little dent on the alloy and the tubeless tyres wont hold air, and people wont be willing to give 6to7k for a new alloy and blame company for that!
4. You can see that many people who infact suffered such fate and were penny wise pound foolish with tubeless in their cars/bikes have now adopted to insert a tube in the steel belted radial tubeless tyres, this is very wrong. You must change a tubeless tyre if there are more than 2-3 punctures which can let water and elements leak and damage steel radial threads!
