thanx Noor.

Heating in a new Bike is normal...it takes minimum 1,000Kms for the engine to settle down into smooth operation.....which is why at this time you are required to drive the bike at lesser RPM and speeds.
Black smoke is because of Rich AFR, and your mileage also indicates that you are running Rich...which is good during run in period.So nothing to worry about...carry out all the required services with the A.S.S, and follow the recommendations as per A.S.S.,and the Owner/User Manual.

thanx PSR. how many Kms more should I wait for this rich A/F to be normal. Its now 850 Kms. hopefully by tommorow it will be 950 Kms. And kindly shed some light on the vibration issue as above 3.5K rpm its vibration starts. i'm feeling the vibes in handlebar,footpegs,tanks (where my thigh sits).

I had indicated in my previous post that it takes at least 1,000Kms for the settling down...It is an approximate indication and so at 950 Kms the engine should start to feel better and relaxed at higher RPM.
However Vibrations are not a welcome sign...Please do mention it at the time you leave it for service...and also request for a change of Engine oil.It will be better if you are present to see the change of engine oil, to ensure it is changed and not just topped up. Otherwise after getting the bike from the A.S.S. change the oil , with the help of any known mechanic...Recommended Engine oil can be bought from outside ..Ensure the oil you buy confirms to JASO MA2 spec..it will be printed on the container.

till now i changed my engine oil two times. Once at 250 Kms,again at 750 Kms from ASS (both the times in front of me ). Planning to change it again at 1500 Kms. But vibes are the thing that is bothering me. I hope they rectify it or else I'm going to meet the regional manager. Anyways thanx PSR and anymore suggestion

one more problem I'm facing in my new hunk is when i'm engine braking, frequently while shifting down from 3rd to 2nd (say) the gear is moving freely downwards. I can't find any gear down that.then putting the clutch I have to move the bike back n forth so as to come down to 1st gear. it happens in mainly 4rth to 3rd or 3rd to second. I don't know what this problem is called. Any comment?

Hard Gear shifts are a part bike being new...still if your clutch cable is not adjusted properly then also this problem can arise...bring it up with your A.S.S. SPECIFICALLY and they will do the adjustment for you.

Hello papan , which is your HH dealer in kolkata ? Anyway take up the issues with them ... one thing I can predict certainly is that they will try their best to convince you that everything is ok with your bike . This is an HeroHonda dealer's usual first step to solving a customer's bike problems ; deny that there is a problem at all ! So go prepared and with some time in hand . Definitely complain to the regional manager until they solve it fully .
Black smoke is caused by excess fuel that has entered the cylinder area and cannot be burned completely. The burning of excess fuel is also referred to as, "running rich." When black smoke is noticed coming from the tailpipe, it is often coupled with the complaint of poor fuel mileage. Although excess fuel will usually effect engine performance, reduce fuel economy, and produce a fuel odor, black smoke from the tailpipe is not, as a rule, a great cause for alarm. Get them to properly tune your Carburettor .

As an personal opinion , I am convinced that the HH 10w30 (MAK) oil is unsuitable for longer rides in kolkata summers . Hence the heat engine-vibrations gear-slipping etc . You can quietly change to a good mineral 20w40 oil yourself after your problems are serviced , without telling them . Since you have already changed oil twice in 1000kms , you can skip oil change at their service too .
I was having similar symptoms during longer rides on my new splendor+ until about 1500k , when I switched to Yamalube 20w40 SL ( from Leaders yamaha , PA Shah road near south city mall ) , that solved it nicely . Yours is even higher capacity 150cc so my suspicion is oil .

thanx pinaki da. Going 2mmorow. let c.will post the experience

Yes. What PSR has suggested, was exactly in my mind. Check your spark plug, it should be in dark color.
I am keeping the P-200 bulb for you, whenever you drop in, please collect it from me and see the result.

thanx bappa da..I will collect it from you

today's Visit to SVC regarding the problem of vibration and smoke

today went to service center morning 7. when the service engineer came I told him that previous service center didn't do anything rather i'm getting black smoke,vibration and heating of engine. even my mileage dropped to 37". I had ]complained to HH REGIONAL office and they asked you to do the proper checking." the moment I said that the SVC guy started saying SIR to me and offered me to sit in the AC room and asked me to wait until the senior engineer comes. Within 15 mins he came and I as pillion went for a TD for 5 kms. He recognized the problem and said OK. it will be done by the best(experienced) available mechanic. in the job card following were mentioned:

1) valve clearance
2) carburettor checking and proper tuning
3) removing and replacing and tightening all the main nuts & bolts.

My bike was on the bay for 1 and 1/2 hrs and there were two engineers tuning the bike. even during the lunch time they completed my bike. to my surprise they mentioned that that there is a bushing where the tank sits on the chassis. that was was misplaced by the previous service center during my first service. after that vibration has reduced to some extent but not fully. they added two additives , one in engine oil and one in petrol. it is from Germany called nano oil booster and nano valve clearence and fuel injection cleaner. After adding it I rode the bike for 25 kms and really the acceleration increased a lot. just a small twisting in fifth gear and the bike is moving at 60. vibes are less but it is still prominent in lower gears at 4K rpm. didn't try above 4K rpm still.
the additives are marketed by mtf automobiles. check this out in Google. But once I'm in fifth gear the bike ha sbecome very smoth than previous. Mileage yet to check.

So, any comments or suggestion please!!

To get such hard work from these lousy HeroHonda boys is an achievement . Great work . Do pass on the contact number of the regional office and the service center where you got this all done , I am on the hunt for a better service centre for my overdue free service . else I will skip the services .
As you were present when the work was done ...
1) what was the findings when the valve clearance was checked ? was it tight , loose or alright ? did you ask ?
2) same about the carburettor .. was it tuned to richer or leaner mix now ? How was the plug looking when checked ?
They aren't supposed to put additives into your fuel/oil to solve a problem . I mean do they mean a new herohonda bike needs those additives to function properly ?? no way !! The bike should work perfectly just on standard unleaded fuel and HH 10w30 oil & a little grease here and there . If there is a dirty injector or improper valve seating or dirty carb , they should disassemble and clean forthwith , no shortcuts like that . Anyway if your problems are reduced to a great extent , do consider moving to a good 20w40 mineral oil as u complete your run in . Honda runs that engine of yours on 20w40 only , they designed it .
