Re: Hero Karizma ZMR (2014 version)

Looks like a manufacturing defect in engine parts....The crankshaft ,Valves, and Cam do not get damaged with bad petrol...unless it is diesel or kerosene adulteration...Even then cam does not come into direct play...My gut feeling is Upper cylinder lubrication had starved., ie., less than required leading to valve,rocker,cam,stem seal etc going bad.....if valve sticks then it will hit the piston and damage the small and ultimately big end of Connecting rod...along with Piston .
Bad engine Oil, with poor circulation is what comes to my mind which alone can account for all the failed parts...
Sad to see this happen to your New Bike...but now you have a complete new innards ,which should give good reliable performance in years to come..
If in case you have to open engine in future, change the High Lift cam to older Cam with lesser lift, which has proven track record.
Good Luck.

Let's not jump guns brother! New products do fail at times and that's how the product keeps on improving. I agree its sad to see it happen on a new bike, but mechanical components do fail at a certain age.
Let's hope the new parts turn rock solid for the years to come.
Peace.

Re: Hero Karizma ZMR (2014 version)

Manufacturing defects are inevitable. Companies offer warranty to cover these. Its unfortunate to have got a defective bike. I am sure things would be fine once the defected parts are replaced with good ones.

Re: Hero Karizma ZMR (2014 version)

Ravi, it depends on your perception. It was a general practice with Bajaj to replace parts under warranty as it is the customers who did actual testing of the bike. Hence general mindset is to avoid first couple of lots until issues are ironed out. Hopefully Hero is not trying to follow the same path.

You have no option but to accept it and move on hoping that replaced parts are good, but you can do your bit by spreading awareness on forums like xbhp and facebook about your ordeal.

It is not wrong to support a company, however when the same company is at fault, we shouldn't be patronising. Why should we be loyal to a company when we are paying from our own pockets? It is company that should be loyal to the customers by providing good products and service.

Honestly I have been in a similar situation and felt helpless. You got no option but to accept parts replacement under warranty. Taking company to court is an option, however it is time that seems more valuable in such situations.

I have hopped from Hero Honda to Bajaj to Ktm, and quality isn't that different. Finally I own a Ninja 300 now and I hope Kawasaki does not let me down.

Re: Hero Karizma ZMR (2014 version)

Thanx a lot PSR sir [MENTION=47074]Divya[/MENTION]Sharan Ravi@17bhp anna.

It really pains me to see the bike in such condition. This is not the first time when I have manufacturing defects in a very trusted product. To name a few : Dell XPS and Sony Xperia LT26i
I have become superstitious now. Also, I am optimistic that once the product is repaired... it proves to be rock solid. BUT, No more big budget Item on my name!!!...

Re: Hero Karizma ZMR (2014 version)


I can feel you bro.

Re: Hero Karizma ZMR (2014 version)

Sometimes it happens due to bad servicing too..In my case I had to replace rocker arm,tappets and piston at 17k km since the tappets weren't adjusted properly during initial runs despite of instructing them to do so.But after the parts replacement, the bike is again smooth as new one..Have done 10k so far without any problem except tapet adjustment.All the parts were replaced under warranty.

Re: Hero Karizma ZMR (2014 version)

Don't worry bro everything will be alright soon..!!...

Re: Hero Karizma ZMR (2014 version)

Saw the new ZMR up hill towards Rohtang Pass. Pulled effortlessly. Looks amazing on the hills..

Re: Hero Karizma ZMR (2014 version)

Guys, I have an issue with my ZMR (don't know weather its small or not)..

Sometimes when I get stuck in Bangalore traffic, cant even get into 3rd gear.
At that time I have to ride in 1st and 2nd gear for long time (no other choice). If I rise my throttle in 1st gear little high, RPM is mounting to 4k whenever I press my clutch or whenever bike come to neutral.

The only solution I found is taking my ZMR to roadside, starting and leaving it. It raises to 4k rpm and stays there for 1-2 min and comes down to 1.5 and behaves normally.This repeats every time I travel in 1st gear.

I reported same thing to service center guy and he suggested me to start the engine and leave it for 5 min every morning. Even though I am doing this daily found no change in it.
Can anyone help me on this so that i can argue with hero service center guy as I am giving my bike for second service this weekend.
Does this effects mileage?

Re: Hero Karizma ZMR (2014 version)

Thanks up not good too much vib tappet sound poor fittings not worthy sorry for this but truth after 1200km bike tappet opened

Re: Hero Karizma ZMR (2014 version)

Did you check the accelerator cable? It could be tight. Loosen it a bit. If it prevails keep the bike at svc and tell them you wont pick unless it is resolved. If they still say it is normal ask them to give that in writing.

Re: Hero Karizma ZMR (2014 version)


Sure Bro..

There is an issue with my Throttle too (Don't know it is related to above mentioned issue or not).
My throttle is very loose, I can rotate it freely till some extent before it actually accelerates my bike.
the free rotation is very less in other bikes in comparison to mine. Last time when I went to showroom, they told me they will fix it when I give my bike for servicing.

Does this matters?

Re: Hero Karizma ZMR (2014 version)

Any one suggest me that any loss in my bike life or performance after tappet open for tic tic sound cure. My bike only 1200 km running, is there any thing for worry

Re: Hero Karizma ZMR (2014 version)

Same problem with my bike its only 3500km run ......
