Air fuel ratio has NOTHING to do with the vibes.Originally posted by social View PostCan the a/f mixture affect the engine vibes? Does a leaner mix make the engine work harder and hence produce a little bit more vibes compared to optimal/richer mixture.
I suspect my bike is running lean. I rode a friend's bike and his was way smoother and also pick up in each gear was better. The engine revved very easily compared to mine. And the vibes were very less.
The friends bike felt smooth because it might had cleaner air filter, much better lubed chain, slack in the chain to the right level, play in the clutch to the right level, road, pressure of the air in the tires etc.
Get your piston rings checked.Originally posted by dead_piper View Postbut when it started there was loads of black smoke coming from exhaust.
Your bike is surely burning oil.
NO.Originally posted by psr View PostBlack smoke is Excess fuel getting burnt...
As winters are approaching, richen the mixture by jalf turns and all your starting troubles will be solved.Originally posted by social View PostBut my bike never starts with the choke on at least with the kick. It barely manages to start with the electric starter.
Replied above.Originally posted by dead_piper View Posthelllllllllllllp., GUYS today whenever i started my bike there was smoke n even when i rev hard its coming., what could be the problem??? can rich mixture setting be the prob?



this problem first started 2 days ago when i started bike after a couple of days rest n cold atmosphere.,
NO, NEVER.Originally posted by psr View PostYes leaner AFR will make the engine vibrate more.
YES.Originally posted by psr View PostSetting AFR ,a little on the rich side is always better.
NO.Originally posted by psr View PostEvery early morning start with choke will produce slight smoke initially.
Manual chaoke is always better than the auto choke, cuz over to the period of time, the sensor gets mind of its own in auto choke and forgets to switch the thing off !Originally posted by psr View PostBikes with auto choke will work better than Manual choke
happened many times in my Scooty pep, i removed it.
Crisp brown burnt kinda color indicates perfect setting.Originally posted by dead_piper View Post@psr:
checked spark plug., it has carbon deposit and no oily feeling...
Post the pic of your disc.Originally posted by naveen2cool View Post
The mechanic there says that my rear disc is worn out
The bike can be revved from morning till night without the air filter in an clean environment.Originally posted by social View Post
And revving the bike with no air filter is a strict no no.
It will make the throttle ultra crisp while making the bike sounding more deep at the same time.
No, it wont catch fire, it wont let the exhaust to throw flames.Originally posted by psr View Postif it backfires will catch fire.

[QUOTE=rennycornelius;526245]Air fuel ratio has NOTHING to do with the vibes.
It does renny. I have made trials with it. Running lean results in more vibrations, as the ignition is not uniform. This characteristic is more dominant in single cylinders and even stronger in oversquares.There's lot to it other than saddle....

Thank you
My first servicing is almost up.....I will ask them to do accordingly
cheers

I have never experienced it in my FIERO and KB100 (which used to vibrate a lot too, at par with RTR).Originally posted by nox2505 View PostIt does renny. I have made trials with it. Running lean results in more vibrations, as the ignition is not uniform. This characteristic is more dominant in single cylinders and even stronger in oversquares.
Never had a chance to play with the settings of RTR.
But with already so much Vibes at certain RPM, i fail to get any siolution for it.The Magician"

I have read in other forums of this happening.In fact the rear disk was worn out within 8 K kmsOriginally posted by thmh201 View Posteven my bike has some problem with rear disk, my bike is only 4mnths - 4500kms old and i hear screech sound from rear wheel, and the break is also very weak.. i'm managing with the front break now...
in one case,and the owner had to change disk and pads to-gether. He was told that the rear caliper oil canister was empty,and the brake had held continuously,without pressure for braking..This had worn out both the disk and pads.The owner was asked to pay 2,500/-...Please make a SPECIFIC WRITTEN COMPLAINT to your A.S.S on this.and get it attended.The disc should not bind and wheel should rotate with little friction only.

i had a small accident..slight scratch on the headlight!and my bike isnt even a week old!!
planning to put stickers to cover it up or is there anyway to adda tpugh up?? my bike is still in run in period and one of my friends ripped the bike to 105!
is this okay? or is it going to spoil my engine and what speed should i maintain?i am maintaining about 55 kmh max sometimes i go upto 60 is this okay, but i try to keep my bike below 4 RPM...i am experiencing large amout of vibes at 48-55 kmh will these reduce after first service??? also the engine gets hot very quickly is this beacuse this is a new bike???

Renny thanks for taking the time to respond to the many queries. I had tried to explain based on my personal experience and of some of my friends..
1.Lean AFR had caused engine vibes in my Honda CX 125 twin(Now not with me),and also in my KB which I presently own.
2.Engine back fire has two circuits.One through the Exhaust,and the other through the intake manifold.Many have experienced the Exhaust one,and only a few have experienced the inlet type.Lean mix,and bad Valve timings(sometimes sticky valves) are the main reasons for it.
3. Temporary black smoke at the time of starting,with choke,is attributed to rich mix. I was explaining to a specific query .
4. In Petrol Vehicles, If rings are bad or if there is oil coming into the combustion chamber and getting burnt,the smoke from the Exhaust will be Blueish ...and there will be oily deposit at the Exit mouth of the Exhaust.
Just sharing what I have learnt till now..

Any high RPM running during engine setting time is not good for the engine.If the ripping had been very short time ..say for just passing another vehicle,and then slowing down then nothing to worry.Normally the setting in is done with respect to engine RPM IN ANY GEAR...which is 4,000 RPM.A new engine will get hot as its internals are rough and have not become smooth...which is why the 4 K rpm limit is mentioned.Originally posted by pranav_salieri View Posti had a small accident..slight scratch on the headlight!and my bike isnt even a week old!!

Remember to mention the Vibration problem at the time you give the bike for servicing to A.S.S.When Was The Last Time,You Did Something For The First Time.

Renny elsewhere in another post I read that there are engine anchor bolts near the engine(small) sprocket which should be tightened for decreasing the Vibrations.It seems most of the RTR engine anchor nuts work loose due to vibes and need to be tightened periodically....Since I don't own a RTR I am unable to authenticate this statement.But I guess it is worth looking into.RTR Fi is supposed to have the least vibes of all the models.Since you own one ,what is your opinion....I am planning on buying a Apache 150 and upgrade to 180..so your input will be useful for me.Originally posted by rennycornelius View PostI have never experienced it in my FIERO and KB100 (which used to vibrate a lot too, at par with RTR).

Why you sold it ??!!!!
And good to knw another KB100 owner, it's indeed a great bike !
I never experienced the vibes slowing down in the KB100, but that was my experience, and i would like to add that the KB100 has the most responsive carb i ever came across.

I thought Back "fire" you're talkin about, RTR backfires a lot but it was FIERO which was the backfire champ...

RTR's vibes is in diff league !Originally posted by psr View PostRenny elsewhere in another post I read that there are engine anchor bolts near the engine(small) sprocket which should be tightened for decreasing the Vibrations.It seems most of the RTR engine anchor nuts work loose due to vibes and need to be tightened periodically....Since I don't own a RTR I am unable to authenticate this statement.But I guess it is worth looking into.RTR Fi is supposed to have the least vibes of all the models.Since you own one ,what is your opinion....I am planning on buying a Apache 150 and upgrade to 180..so your input will be useful for me.
i tried all, tightened things here and there but no vail.
FI vibrates as same as RTR carbed, may be more, it vibrates like hell between 5200-6800, and then after 7000 RPM the pillion refuses to keep his feet on the pegs.
I will strongly advise you to buy 180 directly !The Magician"

The honda parts were tough to get..The KB is still with me..and even recently did a total engine revival for it. I also had a Honda MVX 250..A three cylinder " V" 250 cc engine. The Bike never had vibration in any RPM and you had to look at the rpm and speedo to know how fast you are.It had 6 gears,and in the sixth at 1,600 RPM it will do 60 Kmph.In just 500 mts distance in city I had done 120 Kmph.(80's when traffic was very less).Even in highway it will go effortlessly to 140Kmph...Why I sold it ? It gave 15 Kms per liter,and parts were very hard to source,and the forward inclined riding position gave me back stiffness.Originally posted by rennycornelius View Post..........Bolds.
