Topic Moved to Help Section.

Quite a funny and strange case you got there. Please give more details on this topic, including the queries asked by members.

Did you get her serviced from time to time from the official showroom of Hero MotoCorp? Did you get oil changed in the services?

hello xbhpians,
This is my very first interaction after being a member.
It's been an year since i bought my HH karizma R.I am fed up with the problems i am facing.
Problems faced:
1: gear is much on the harder side.Especially shifting from 1st to 2nd.It gets stuck in the neutral. - Common problem. - Need to adjust the clutch and probably shift to 20w40 grade oil.
2: Starting in mornings is a nightmare sometimes.Need to depress the choke.Is using choke common with all the karizmas. - Reason could be AFR is lean. Adjust to AFR to optimum.
3: Sometimes the bike wont start upon cranking.Need to open the seat and crank.(seems funny!).Trust me, i am serious. - Funny indeed! AFR adjustment will do away this. Also for your satisfaction, check the Air Filter path for any blockade.
4: The engine sounds smooth in the mornings(or rather during first start of the day).But after some 15 odd kms it tends to be quite rough.And i feel the power to be dropped a bit.(again seems funny).But please trust me.
- This is heating issue. This could be because AFR is lean and 10w30 grade oil inside the engine (blame HH service center). Adjust the AFR and changing engine oil to to 20w40 grade might resolve the issue.
5: I am getting a FE of 29 which covers 80% city and 20% quite open stretches.And mind u,i am a sedate driver.I keep the revv counter below 4000rpm max in any gear. - There are several factors affecting the mileage. Concentrate on the other stated issues and we can look into FE concern later.

I request you guys,if you could lend me with a solution to my problems.And suggest me with a good mechanic in bangalore who could address the problem(he should be a bike enthusiast).Because i have showed my vehicle to 5 mechs who failed to rectify.Thank you

- Note the above points and you can ask any eligible mechanic to check. This forum is more than just a google-find for mechanics. Here we identify and provide you solution closest to the issue.

Welcome to the forum bro!
Quite a few niggles there. Don't worry.

Come down to Dream Machines, Ashwathnagar

1. How many kms done? Get engine oil replaced. Use Mobil1 10w40 FS. Awesome oil. Costs some 1.2K per liter, but it is superb.

2. It is common. Use the kick in the mornings though.

3. Get this issue checked.

4. Get air filter replaced/checked. Engine oil may be the culprit too. Change it.

5. Needs servicing.
a. Get the AFR checked. You may be running rich.
b. Post a pic of your spark plug.
c. Engine oil change needed.
d. Chain lubing needed.
e. Air filter change/cleaning needed.
f. Keep optimum tire pressures. Don't fall in the 25 front 35 rear funda at petrol bunks. Insist on 29 psi front and 33 psi rear as prescribed.

Seniors, please add.

**SriramEfunds** · 08-25-2012, 01:15 AM

@Divyasharan - Help him to check the points I've asked him to stated and probably you guys can resolve without service visit.

Problems faced:
1: gear is much on the harder side.Especially shifting from 1st to 2nd.It gets stuck in the neutral.
Use good quality engine oil. Also adjust the free play of clutch as recommended in manual.
2: Starting in mornings is a nightmare sometimes.Need to depress the choke.Is using choke common with all the karizmas.
Set the Air mixture to optimum. If your engine is running rich or lean,in both case starting problem will occur.
3: Sometimes the bike wont start upon cranking.Need to open the seat and crank.(seems funny!).Trust me, i am serious.
It is because your engine is running rich. The engine is flooded with petrol and thus needing more air to start. Sometimes when the engine is excessively flooded with petrol, mechanics open air filter and crank so that excess petrol will get burned by more air.
4: The engine sounds smooth in the mornings(or rather during first start of the day).But after some 15 odd kms it tends to be quite rough.And i feel the power to be dropped a bit.(again seems funny).But please trust me.
Power loss when engine getting heated is a sure sign of rich mixture. When a engine runs rich then it will feel smooth when cold and on warming up will feel lazy to rev.
5: I am getting a FE of 29 which covers 80% city and 20% quite open stretches.And mind u,i am a sedate driver.I keep the revv counter below 4000rpm max in any gear.
Again your mixture is rich.

All your problem has one solution. Your bike is running rich. See the reason in bold.
First check the air filter and the passage to air filter. The air filter should be clean and the passage shouldn't be blocked. Sometimes some put a piece of cloth under seat which blocks air.
First make sure the air passage is ok and then set the mixture to optimum. Do not run rich or lean, both have their own problems.

**SriramEfunds** · 08-25-2012, 02:13 PM

@Sibun:- HH no way sets it up rich mixture at all atleast what I know from my ZMA. How do you conclude it is running rich?

@Pritish:- Here is what you can check yourself.

1. Pull the spark plug and see what color the porcelain part in the center looks now.
2. Turn the AFR screw clockwise to close it till hand tight. Now the bike is running full lean.
3. Then slowly turn the screw ant-clockwise upto 3 turns. Run the bike and do check the spark plug for color. Ideally the bown tinge depicts running good (optimum) and whitish means running lean. Check the plug color after say 50 odd kms.

The factory tuned bikes do not have any problem. The problem is with mechanics in service center. They just like to fiddle with the mixture setting screw uselessly even if the customer doesn't complain.
During the first service most mechanic fiddle with carburettor if you do not check them.
I concluded that he is running rich because:-
1. low mileage
2. Performance decrease when bike is heating up. A rich mixture will always bog down the performance as the engine gets warm.
3. Opening of seat as it indicates flooding of engine and thus requiring more air to start.
Another thing i forgot to mention, check the choke as in most bikes the choke remains slightly open and thus cause the bike to run rich.

It's been an year since i bought my HH karizma R.I am fed up with the problems i am facing.
Problems faced:

Please mention year of make, Kilometers on ODO,and Service History

1: gear is much on the harder side.Especially shifting from 1st to 2nd.It gets stuck in the neutral.
Check and change your engine oil to any good 20w40 oil
2: Starting in mornings is a nightmare sometimes.Need to depress the choke.Is using choke common with all the karizmas.
A lean AFR setting will warrant use of choke..Pleae read Mr.Sriram's reply
3: Sometimes the bike wont start upon cranking.Need to open the seat and crank.(seems funny!).Trust me, i am serious.
You might have CDI connector loose contact, or have something blocking the air inlet hose under the seat
4: The engine sounds smooth in the mornings(or rather during first start of the day).But after some 15 odd kms it tends to be quite rough.And i feel the power to be dropped a bit.(again seems funny).But please trust me.
Thin /used up Engine oil can cause this kind of problem
5: I am getting a FE of 29 which covers 80% city and 20% quite open stretches.And mind u,i am a sedate driver.I keep the revv counter below 4000rpm max in any gear.
How many Kilometers since you changed your AIR FILTER, Spark Plug and engine Oil ?

I request you guys,if you could lend me with a solution to my problems.And suggest me with a good mechanic in bangalore who could address the problem(he should be a bike enthusiast).Because i have showed my vehicle to 5 mechs who failed to rectify.Thank you

karizma

First of all, i would like to thank all you guys for the quick respnse

The screw that adjusts engine rpm is the AFR adjustment right??(sorry, i am new to this)
And there is one more problem

As the engine gets heated up after running and power slightly drops which i mentioned before, there is a loose sound somewhere near the engine or the bore head.I showed to a mechanic regarding this issue,he said there is something called knucle(pardon me if i am wrong) on top of the bore head which needs to be checked or there might be problem with the timing chain. The is sound which is quite noticeable is annoying.

Here are the pics of odo reading and the sparkplug.
And if i quote for individual person,i am getting message is too short.

No, that idle rpm is different from AFR screw. You may need to adjust both AFR and idle rpm screws.

First identify the AFR screw. In the below picture of P180 (as example only), screw below the brass spring, is the Idle rpm.
In the picture with an arrow at the top is pointing towards the "AFR Screw":

For your Karizma it could be a different carb.

As for the sound, we can't understand what sound it is. Maybe, its the tappet which should be adjusted with a guage for best results, ok? Remember to tell this to the HH Mechanic.
I suggest you get the noise rectified first, before touching the carburettor.

**SriramEfunds** · 08-26-2012, 12:28 PM

@Pritish:- What we want to see is the spark plug removed from the bike and post the picture as shown below.

**Pritish rajashekar** · 08-26-2012, 12:32 PM

Bad experience with HH Karizma R

thanks samarth 619 for your response.

Here are the steps i will be following now:
1: Check for the sound, with the mech.
2: Adjust AFR screw and idle screw.
3: Shift to 20w40 grade oil.
4: Check the air filter.

Is it proper?
