Hi Psr/Divya Sharan


My name is Anoop and i am following this thread for the last one year. I am ownimg Karizma ZMR (hero honda version) which completed 17000KM within 20 months. Recently I have changed the spark plug, airfilter (@ 14000 km) and use to change the oil every 2000Km. (Mileage about 42-45)
Everything was fine until my roommate brought the same Karizma ZMR (hero version) just 3 weeks back. I felt my roommate's bike is very smooth from the day he bought but the same is missing in my bike. :-(
Is the new hero ZMR bike is better tuned? I would like to have the same smoothness in my bike as well..
Can you please suggest any thoughts, so that I can guide the mechanic in hero showroom to do the same.....

Once the bike is used, and in your case, 17k kms, do not expect the smoothness of it to come back as it was wen new. Several factors are responsible for it. You can only minimise the vibes but not make them as they were when the bike was new. Also you would have been habituated with your own bike and hence riding a new one wil make you feel so.

Here it is. But I wonder how many SVC are equipped with such a setup!



^^^ +1.

A new ride will have all panels/plastics/engine/exhaust/chain/sprocket etc tuned in factory spec condition. It is as perfect as it can get.

Now, mechanical parts deteriorate with the mileage clocked. Plastics start rattling on use. We can only aim at achieving near factory efficiency from age-ing bikes.

Get the plastics damped with double sided tapes/tube to reduce vibes/rattle. Since you're at 17k, sprocket set may need replacement sooner or later. That'll smoothen out the ide to a great extent. Use xW40 engine oils for better performance of the engine. Keep proper tire pressure, clean air filter and spark plugs every 3-4k kms and replace them @ 10k and 12k kms respectively.

I am facing the same issues on my Black Pearl.. Still Haven't found a solution to it.. I am taking a guess its the charging relay at fault in my bike.. yet to get it checked as they said it will cost me some 2300 in case i have to get it changed.. if I keep the headlight turned on for some 15 odd mins.. then the battery would drain out and I will need to push start her.. which is pretty hectic

Dude, the electrical system in our bikes is tuned such that,the headlight wont drain faster if you use 35w bulb when bike is off.Now ,i guess you have upgraded your headlight bulb to 55/60w.The dynamo is capable of providing the sufficient current if the bike is on and hence you may not face much problem when you are on move (Provided you don't run your bike "only " at night).But with 55/60w bulb, if you keep the headlight on when the bike is switched off am sure it will drain the battery.If you have any problem of battery drain during riding,then you need to check the relay and in few cases need to check the dynamo.(If you need to keep headlight on for longer time when bike is off, upgrade to 9amps battery.)

If the Bike is able to start with push start, and runs normally with headlight, horn(S),turn indicator etc., without showing any electrical problem, then it is the battery...
to Trouble shoot do the following..
1. Check battery Voltage when engine is off, and in the morning before starting....it should be 12.4 to 12.9 Volts DC.
2. Start engine and measure the voltage across the battery...it should be 14.2to 14.8 Volts.....if it is above 14.8 ie., 15 volts, then the battery is suspect.
3. Switch on head light , when engine is running at idle,and check batery Voltage...If it dips to 12. then battery is suspect...on revving engine to 3,000 RPM, if the voltage increases this further confirms it.
4. If the Voltage does not come up to 14 Volts at Idle RPM or when RPM is increased to 3,000 RPM ,then the RR unit connections to be checked...and if it is ok suspect RR defect or stator coil having shorting turns...

If the battery is sealed Lead Acid Type, and not AGM type, then the specific gravity of the Electrolyte will show if any of the cell is defective...the sealing is temporary and the battery check guys will know how to do the job..

A new bike will have comparatively closer tolerance in moving parts, and so likely to have less vibes....that said what is the oil you are using ? engine oil and the way the owner uses the engine will make all the difference between a good and average engine feel....

Thanks for welcoming me back bro though most of the time I was here only as a silent reader
yes I was using HID but once my battery got drained once,I stopped using it n had only low beam as working light since then which is a normal yellow bulb..will take the bike to service centre & battery to its service centre to know what's causing problem frequently..my night ride is of just couple of kms that too not everyday so its not a lot but still then its creating a problem..

yesterday my friend took my bike n while returning from the destination,the bike didn't start so as per he told me,he tried the basic push & start process & it started..so that means most probably the battery is at fault..will check it by other methods as you suggested as well..

Thanks guys for your valuable suggestions

Not really mate.. I am not facing this issue now.. I have been facing this issue right frm the time I purchased my ZMR.. when I take it to the ASC.. they just charge the battery and gave it back.. this happened with the stock headlight setup.. i understand what you are saying.. but many people are using Osram Night Breakers and I don't see them complaining so I am just guessing its the issue with the Charging Relay.. Gonna go down now and do what PSR sir has said.. I will give it a try.. if its the issue with the battery.. then i am gonna for sure go for a bigger battery.. else I will have to get the Charging relay checked.. But thank you for your valuable reply

Follow exactly PSR sir's instructions. I have been using Osram NB 55/60w bulb for the past 5 yrs without any issues.

Hi PSR sir and Ravi.. i checked it out just now.. I noticed that at Engine Idle.. the voltage across the battery was just 12.86V.. when I turned on the headlight.. it reduced to 11.56 to 11.96V.. when engine at 3000RPM.. it was somewhere around 13.60V..

What should I do now?? Please suggest.. during night.. I am not able to keep the light turned on for more than 15mins.. maybe even less than that.. This is worrying me now and its just 2 months left for my Bhutan Trip..

Check :

1. Loose Terminals
2. Rectifier alongiside the battery ( chances are its kaput and not aiding in charging the battery)
3. Battery Kaput itself and needs replacement, how many years have u used this battery?
4. Are you running HID? if yes higher voltage battery will help

The spark plug and airfilter needs to be changed every 10000 kms. Wrt to smoothness, depends how your ride, thrash it often across rev range or drive in power band. Also changing oil at every 2000 kms is not a sensisble thing, the manufacturer may say so but ideally the HH oil is no ggod than 1200kms, the advice is to change the oil every 1000 to 1200 kms.

The filter can also ideally last 10k kms, but dusty environments can lead to changing filters at as early as 7k ams.

To ensure good performance, clean chain and sprockets with diesel , specaillay the front sprocket
look out if u need replacing the acceletor cables and clutch cables changed as well

spot on , please follow this. change if closing to 8k to 10k kms

this is not the right method to do things..ravi and myself have higlighted how to clean air filter and chain
