Before it was nearly 4k rpm,guess it happens due to AFR tuning.

Will do that see, what it does good to the overall performance.

You guys have a good city,Here i cant go above 40-50 in cities.

Yup.. Roads here Delhi are pretty good, so can easily achieve such speeds.

Another issue has just clicked in this morning, before going to office I thought to tune in the AFR. Before doing this, I went for a small ride and found that my bike started to feel heavy as from the last night adjustments to throttle slackness.
Now, what could be the issue here

, I was not able to zero it out. So, thought to discuss with you guys before going in for AFR tuning..

PS:- Vehicle zooms once past 5k RPM. It's a bliss! With Deva at back seat she was comfortable doing 90kmph.

Although was careful on the return journey at night. Did not face engine kill this time after idling adjusted, however, it was brought to my notice that once the engine is warm is was around 1.5k RPM. Is this expected?
Happy to note you are enjoying your new bike, and like I said the power after 5 k will be different,than stock.A difference of 300 RPM between hot and cold is ok..honda recommends idle 1,400RPM ...but says nothing of hot or cold engine.Since your's is a new bike heating up will be a little more than a set in old engine of 10 k Kms.As you cross 5 k Kms the engine will start becoming more smooth.
Ride safe.

Its normal for the engine rpm to idle slightly(extremly small margin) above 1.5 on the tacho after extended warmup. But cold idle rpm also has an influence, so whats yours when cold???

If experiencing engine kill problem do the 4turns thingi... It worked fine for me, bike starts with single push(Credits psr).
Mr.Sriram's bike is new and in warranty, so stock settings are not changed..and he is in touch with me .

And have you noticed that with pillion even if you slightly apply front brake the pillion starts to take flight, is it due to soft front suspension, If yes is there any possible way of adjusting it like done with rear shocks???..
This problem is because of the sharp downward angle of the seat, and seat cover material being slippery.

According to psr,an idle rpm difference of 300rpm between cold and hot idle rpm is normal,So if you cold rpm is nearly1200 or 1300 rpm,then guess its normal.

I think the difference in RPM to speed rests with the change in oil grade to 20w40. New bikes manage this even with 10w30 but as it ages clutch slip starts to set in and a thicker oil is able to stop this for the time being.

From my little experience its caused when you dont properly warmup your bike, i had experienced this with 20w40 in mornings.. But will go away after riding sanely for about 30mins or so....

Sir, I think you've forgotten, But I was experiencing this from day one of purchase and you advised me to do the 4 turns and after that my bike works well,
What i meant to say is that the SVC people have a habit of meddling with things they are'nt certain about, as proof, I had my AFR screw marked with a blue marker when i got my bike, and i dont think the manufacturing plant did it. Btw one more thing to notice is that, 4 turns is'nt the stock settings... It was different, sorry I dont exactly recollect by what margin though(cause i was in a hurry to fix my new baby, yeah and mine done 550kms as of now).

This problem is because of the sharp downward angle of the seat, and seat cover material being slippery.

Yup sir, The silly guys even teflon'ed(so called) my seat.

In my case, the AFR was never touched. Also, the idle RPM at cold is around 1.3k (approx). The only that my pillion got me point out about the RPM when he was getting dropped.

FYI.. The factory setting remains the same and I was present during the entire service, so assured of any tampering with the settings.

Did discuss with PSR with the regards to FE as I was getting only 33kmpl. However, did not bother much. I usually take my bike during weekends and would not restrict myself to 100kms radius. So it is!

Front brakes:- I don't do brake and go ride. Most of the time it is accelerator cut to allow engine do the braking a bit and then negotiate if hard braking is required. As far as I know the front brakes are feather but effective and will not make me or my pillion dive unless I stand on the brakes hard!

Yes I do know that your bike is new, and facing cold start problem...I suggested the 4 turns to help you out...since your SVC was of no help.......Mr.Sriram's bike does not have this problem, so there was no need to adjust his AFR.....and the way SVC looks at warranty is different in different places....
I do not wish for any member to try out anything unless they have faced problem, and I post my suggestions when it is of use and welcome.
I had also repeatedly been posting that the ambient temperature plays an important role in the bike's cold idle RPM. In chennai it is very hot now so no body will have cold start problem...see the same thread in December, and you will see many posts from Chennai to Delhi and northern parts of India on this subject..
As for SVC most of them are good for water washing and oil change only.If you ask them something more they will either say it will not suit the bike or will void warranty....how many of them know of AFR ? and how it is adjusted..I must say members in this thread are knowledgeable and open to sharing..

Your lucky, Anyways just as a precaution observe the AFR screw and see if there are any marking or anything, Im repeating this cause me and aneesh have seen how they handle our bikes at SVC.

LOL.. Bro your getting 33 and still complaining??? Mines almost 20 days old and I'm only getting 29kmpl..What say? But still the shocking fact is Vineeth is getting 44kmpl. , So guess theres only one thing left to do, TONIGHT GOING TO SLIP INTO HIS GARAGE AND MESS UP HIS AFR...BUHAHA!!!!

Front brakes:- I don't do brake and go ride. Most of the time it is accelerator cut to allow engine do the braking a bit and then negotiate if hard braking is required. As far as I know the front brakes are feather but effective and will not make me or my pillion dive unless I stand on the brakes hard!

Thats good to hear, guess Im the only one facing this issue cause of teflon'ed seat

Oops... Sorry.. When he said engine kill i thought it was cold start, Now my question is, what did he refer by engine kill???

**ashwinprakas** · 06-27-2011, 03:28 PM

@PSR,

Sir did you see my post in which i showed a pic of my bike leaking oil??? Sir is it okey if they use used oil(nt sure but it was blacker than my bike

) for lube'ing front sproket???

And what do you think abt the carburetor hole modd i.e on a pre run-in bike???
And is there by any chance a possibility that you'll make a detailed guide with pic's based on the above...?

Mr.Sriram faced the problem of engine stopping when he decelerated from speed and stopped...his idle was 1,000 RPM cold, so this was raised to 1,200 and now he does not face any problems.

**SriramEfunds** · 06-27-2011, 03:38 PM

@Ashwinprakas

I was not at all complaining on the mileage return from my bike, I don't recollecting posting any. I'm sorry if your school of thoughts meant discuss means complaining. It was only a find what the FE because just happened to check else would not have bothered. I have already clocked 1300kms and planning another 1000-1500kms ride coming weekend. So FE is not a concern but to check a good health of the bike.

Engine kill:- I addressed the issue with PSR as '@PSR' just that he knows what happened to my query. I know this is being discussed OT and Online. Sorry about that.

What really happened the other night was, taking off from a deserted signal (i always stop at red even at midnight), the engine shut down with a twist of throttle. And once when on the move slowing down at a particular point when the throttle closed. So discussed with PSR sir and the idle was corrected (+).

Yes as per pic you posted it was excess oil that was dripping as black goo.I had, and still using Castrol Bearing Grease and it is good. It reduced my chain noise by 50 %, and chain rotates without clicking noise.

And what do you think abt the carburetor hole modd i.e on a pre run-in bike???
If you mean hole in carb slide......It can be done, and it will not affect bike negatively, since it will provide richer mix.The FE will go for a toss, but the response will be addictive..
And is there by any chance a possibility that you'll make a detailed guide with pic's based on the above...?
Possible, but needs a thin precision drill bit, a machine with accurate chuck, and a good knowledge about Carbs..The mod will necessitate disassembling the carb's internals, and is not a easy DIY to re-assemble correctly without damaging the slide, needle,and rubber skirt....Definitely not a easy DIY, and wouldn't advice any one to attempt,without precision equipment and knowledgeable person to do it.If you want to know of the procedure I had already posted about the same...

I did warmed up my bikes for 4-5 mins but still it felt on the heavier side.

@ psr sir : Your say, on the post I had made earlier on the heaviness that I felt after warming up the bike adequately this morning ??
