not related to tubeless tyre.. irrelevant

our rim is 18" there are lot of options available for 18". Ceat vertigo is good too... if you have any doubt about tyres.. go to universal theard-- tyres... Mr. Go Green will help you with that...

i never exp this issue... if you know that you not gonna use the bike for sometime.. then try following storage procedure given in our manual.

Better change the battery... i always try to start my bike morning with kick only... my bike starting in one kick.. and at times i will also feel the vibes... its better to start the bike run in idle for 1-2 mins.. then ride in average rpm for about 2-3 kms.. then race.

i was busy with work... no times at all... last sunday i went to my native in my bike... 160 kms up and down... awesome trip. engine was very smooth.. return journey was cool even.. as i came in direction with wind.. pick up and top speed for amazing.. i was able to cruise at 90 kmph. Guys you shd really try gulf oil... (im not working for gulf) from my exp its good to use in our bike

@akf... i replied to ur message... dont trust SC guys..

what do u mean by irrelevant dont u know that the first model of honda stunner came out with tubeless tyres?

Thanks bro, by the way what happened to your GS?

Iridium plugs are not yet manufactured by NGK for GS. I had enquired it the moment the bike was launched,so you need to use the stock NGK plug which IMHO is not at all bad.

I think Iridium plugs will increase the economy in high engine rpm. But its sad to hear that NGK is not launching one for GS.

The GSR needs to be high revved if not hard revved.........after 2000kms only.Its max power comes out at 8500rpm(higher engine speed so high road speed) like the Shogun.Yes GSR can carry speeds past 119km but if given the road,no crosswinds and a bit of crouch.Also GSR will kill most crosswinds bcoz of its heavy momentum.The bike redlines at 9500 I think.Its not logical carrying it beyond that.Also the engine oil here becomes the decisive factor.More Viscous the engine oil more better are redlining speeds.

120 would be achievable, above it would need some mods rite

. My friend changed to fully synthetic after first service

, I tried to stop him but in vain

. GS's red line is from 10K.

Dyno charts indicate that torque starts to decrease after attaining its maximum value (@6500 rpm)

, but the Bhp is product of torque and engine rpm. So even if the torque is decreasing the higher rpm will compensate it and maximum bhp is achieved

(@8500) after maximum torque rpm. Theoretically its the perfect time to shift as the torque will be more in the next gear and can provide better acceleration. When a vehicle fails to accelerate means, the aerodynamic drag is equal to the maximum engine output. So as you mentioned there is no good by revving past 8500 rpm ( not 9500 )as the engine power will only decrease after that point. It's really confusing, I dont remember what was the rpm when I clocked 113 it was around 9K i guess.

PS. If anyone is interested to see the dismantled engine of fiero, check this link

Welcome Back Vishal... I had a plan 4 months ago to change the engine oil... But did not do since it did not cross 10K on the ODO then. But after it had crossed (It is 11.5K on the odo now

)... the engine is too good in terms of refinement... So now I never feel the need to change the oil...
Probably we can go for a different brand like Shell, Motul, Elf,etc.. but I second the opinion to stick to the 20W40 Mineral oil grade...

Thanks mate.Great to hear you have crossed 10K on the odo.The engine really frees up post 10K mark.Yes you can try Elf Motogold Pro 20w40. I use it in my Fiero & its a good oil & costs only Rs.200/- per litre.

Plus always change the oil filter on alternate oil change & always pour in 1.1ltr of oil.

Thing to note here is,Once you switch to FS oil & use it regularly & enjoy the ride.Someday if you switch back to Mineral oil,you will feel roughness in your engine & wont enjoy the ride.So its your call people.

I did not buy any other bike but spent some amount on my Fiero & made it run like new & now I am in love again with it,covered 98,780kms on the odo.Will post a pic soon.

I have tried the Iridum plugs on my Fiero for almost 30k on the odo.Had got them from Dubai when they were quite new in the market & not available here.They hardly make any difference(from my point of view & riding pattern).I never felt any increase in economy nor in top end or any other thing.

@Joshee, if we were to change oil filter than do we need extra 200ml oil for it also?

Elf Motogold Pro 20w40-----is this mineral oil?for how many kms it wil last......currently i have the castrol active in my gs..but once 1000k is completed it seems that it has lost its.....viscosity.....gear shift becomes hard....and engine become more rough when compared to earlier....

Hi Nageswer,

You do not extra 200ml if we do a filter change.It still remains 1100ml only.This is what I am doing in my Fiero & use to do in my GS which has the same oil filter & same volume of oil.

Elf is mineral oil. My daily running is around 60-70kms & occasional long rides.So I change my oil every 2000kms.Keeps the engine in good health.My advise would be the same.

I would stay away from Castrol.Off lately it has become a bad oil(as per my experience).I had put fresh oil & been for a long ride for 800kms.Upon reaching my destination,I checked the oil & to my surprise not even a single drop in the chamber.It bloody vaporized

. From then not using Castrol.

You can write to Elf India enquiring about dealers in your area. Here is the link. Engine oils, Greases, coolants, lindustrial lubricants, elf oil - ELF oils India

Guys I need to ask a favor

, is there any chance to improve the braking by replacing the brake pads with a high performance brake pads

. Is something like that available

? B'lore guys

you people have highest probability for a hit, please inquire ........

If the economy remains unchanged

, that means our stock plug is already damn good

. I think since Castrol is a popular brand, it have more duplicate versions and finding real one is real difficult. Currently Im using Castrol Activ

, will be very happy if it lasts up to 1500 km

.

Thanks buddy

, if it runs 1500 km I'm more than happy

. No synthetics before 10 K mark

, it may will cause glazing and the engine mating may arrest

. After 5K we can go for semi synthetics and after couple of changes

, if still not satisfied one can go for synthetics

. Im not that of a high revver

, so I think semi synthetics will be good enough for commuters like me

Vishal

hey Vishal, long time.

I was so close to buying a bottle of petronas sprinta but after reading these comments about synthetics i'm back to square one

I had even asked the SC and they said ok, get the bottle, using FS oil is ok, we'll change it and give etc etc (my bike has covered only 4500kms)

The problem is, 10,000kms is just too long.. it may take 1 whole year for my bike to reach that mark

Does semi synthetic give the same smoothness feel of synthetics ??
and what engine mating could be there beyond 5k kms ? isnt everything set in by then ?

I got my bike back from servicing yesterday. they've put some stand by battery and sent my battery to exide for replacement.. finally !! (had problems with it right from the start)
I'm keeping my fingers crossed that i get a new one.

Hi guys my small ride report after doing 400kms on Odo doing 70kms everyday now on the Greater Noida Expressway. The Gears have become smooth but the engine does feel rough and sometimes i feel that when i shift to a higher gear i feel a kind of jerk as if after i increase my throttle a bit the bike responds a second or two late.

Overall i am mostly driving at 6th gear due to the highway and around 52-61 Km/h sometimes i do go over 62 as well this is around 4.5K RPM so i want to know is this fine i never maintain constant speed like not more than 5seconds on same speed usually i apply a little braking slow down and start up again.

Only disappointment so far is rear brakes they are really worthless the discs are good but off late even they have started making some noise. The mileage i think i am getting around 50+ will give a report in 2days time.

One thing really important i want to know when i accelerate there some kind a click sound i don't know if this is coming from chain or something else. Also click click sound coming from engine which anup said was normal. But when i started my bike today morning and went into 1st gear there was a click click sound when accelerating can anyone clarify about this.

hope after 1st service the roughness in engine goes as most of people have said

**MSN1** · 06-09-2010, 10:52 PM

The same thing happened for me before the first service
i think the roughness is due the the new engine small dust like particles will settle down in the engine oil as all the new parts are settling slowly
i would say it is normal will be cool after first service
do try to change oil again at 1600 kms

regarding the back break ask SVC guy to look in to it am sure even though it will not be good coz

Back Break will bring down speed it wont stop the vehicle
combination of front and back will do the best job try 60:40 method

occasionally crossing the run-in speed limit doesn't harm but always crossing does

Adi, you dont need to be so cautious while riding when people say not to maintain constant speed they mean for some minutes and not just few seconds. It will be so tiresome to vary the speeds all the time. You can do some short bursts of speed past 5K mark and then reduce the speed it will lead to loading and unloading of engine.

When we open throttle air flow to carburetor increases and this will suck more fuel and form air fuel mixure. But there will be a small lag to form the right mixture, that why you experience that sound while accelerating.This also happen when you try to lug engine in top gear. Shift up when you reach around 4.5K and shift down when you go below 3.5K then you wont get that sound.

The other click click is very normal, when engine is cold the oil is thick and the idle rpm may drop below 1000 rpm depending on the air temperature. If you are getting the sound every time when you roll of throttle just increase the idle rpm to 1500 rpm when engine is warm. Its not advisable to adjust the idle rpm when engine is cold as this may lead to increase the idle rpm past 1500 when engine get into operating temperature.

Ride safe........

I am talking about Top speed here.........maximum top speed attainable for any bike at anytime is at redline.For the fifth gear......you will reach a maximum top speed.Then if one slots to sixth gear......which is meant for cruising,Rpms fall and then increases but not till redline for sure.RPM in cruising gear never fully redlines......hence mildly reduced TS

Though like bigger GSXRs,if the bike also fully redlines at 6th gear it will surely do around 122kmph.

Your info above is more relevant to drags........

If you dont have any problem with pick up, top speed, vibrations past 5K or so, then don't worry its running in optimal tuning. Creeping of vibrations as you rev engine is a sign of bike running lean or rich. The other method to check is to examine the electrode of spark plug, remove the plug and see if its tip is light brown in color its running in optimal mixture, if a white gray tint lean and black if the mixture is rich.

Have you decided to go for NGK Iridium

, please post the number of the Plug

. Our GS have NGK but its not Iridium

Stock Plugs are NGK in our bike but that conventional. Not Iridium.

I think you didn't get my point

. This is just my logical reasoning

, in 5th (or 6th) gear the maximum power is attained at 8500. On revving past 8500 rpm the power will only reduce

so do we need to rev past that mark

, the best will be to keep the rpm at that point and see how far the bike accelerates

.

! Since he is my best friend, I believe him. He did it with two of his friends P180 UG3, P150 UG3( My friends own bike), they did 122 and 118 resp. GS smoked them with a 130. Initial lead by P180 ,shortly followed by P150 and GS. GS covered others shortly reaching around 100 and then slowly pulled away

. Seems like he is mentioning about his dream

.

This will be an entertainment for us, the only thing I didnt like is that he actually owns P150 rode his friends new bike which hardly covered 1500 kms and hammered it past 10K rpm ( His friend wanted to know the top end speed

and asked him to drive it

).

omg!!!!!130 wid a pillion!!!

it sure is entertainment for us!
one cannot resist the desire to hardly revv a bike if the owner agrees........
