Hai all .. I need some help.
I am using a 2007 April model Karizma (19 k kilometers) for last three months ..i bought it second hand ..
The bike is fully in stock condition (except the 55/60 w Philips extreme power headlight I fitted).
After i got the bike I had to change many parts including clutch plate , clutch plate assembly (full), cam tenser and some other stuffs (and some body parts too including front cowl ).
Now The bike is running smooth and fine and got a max mileage 42 , min 28 and giving me constant 35 avg mileage . I really love the bike and now addicted to it especially the way it cruses on 80 at 5 k RPM .
I am now working in Chennai and I went to Pondicherry , Bangalore and some other Road trips with the bike and it is simply awesome for touring .
But now I am facing a problem the bike is not getting a good top end . I have touched 130 on it but the problem is the bike is showing variable top speed. Most of the times it is not crossing 110 (with pillion)
And sometimes it got stuck at even 100 (Rpm around 6k not going above) . The Rpm is not going above 7 most of the times (at 5 th gear) . But the initial pick up is good. it will touch up to 100 easily but after 100 the performance degrades .The confusing thing is that in my pondi trip I touched 130 with pillion(Rpm 8) and on for first two hours on the Bangalore trip the bike was touching 125 but after two hours it refuses to go above 110 whatever I do . These days the bike is stuck at 110 top speed . I am really wondering what’s wrong with my bike . I took it to one Mechanic, told my problem but after servicing also the problem exists After that I tried two Hero Honda service centers but no change.
Can anyone tell me what will be the problem? (or which part of the bike wil be the probably cause) Can any chennai Xbhpians help me to find a good Karizma Mechanic ?

your bike has clocked 19000kms degrade in performance is normal

Jithu

i agree there will be performance degredation as the bike is gettign old
but

1. My freinds karizma 2.5 year old stil crossing 120 with ease .
So we cannot say its becuase it has done 19 k .
2. My bike itself crosses 120 ( it had tocuhed 130 ) sometimes but mostly it is geetign sucked at 110 , so my exact problem is not only less top end but Varibale top speed

so there must be soemthing wrong with my bike and i would like to know what is it . i hope experianced bikers and other ZMa owners here can help me sort this out ..

If it is difficult to figure out what the problem is exactly from the details i gave , Zma owners please reply to the following questions .It will help me to find out my problem

1. In 5 th gear whats the maximum Rpm attained by your bike?(how old is ur bike?)
2. Whats the top speed you are getting? and at what RPM?
3. Does wind affect the top speed? (the thing is that when i travelled in opposit direction of the road i am getting more top speed)

2.5 years old what does its ODO displays.
may be it is problem of clutch plates and you need to do decarbonisation it will have huge impact on engine

Jithu

the 2.5 year old karizma already done more than 25 k .

Regardign clutch plates i already replaced not only my clutch plate but the
full clutch assembly.

Stil i have to do decarbonisation??

you may opt for decarb, but pls also get checked your speedometer it may also have some problem which was sorted out in mine p150 showing variable speeds at same rpm's.
pls also check air filter,carboretter

Jithu

Thank you for your suggestion ..

but my speedo meter is workign fine i cross checked it many times ,
plus at one RPM it will show only one speed whenver my max top speed
changed the Max RPM is also changing ..so it wont be the same case of your speedo meter i hope.

Will Hero Hond service centre guys do this decarbonisation? Is it effective? (sorry for the repeated questions , these terms are entirly new to me )
How much it will cost?

yes HHSC should do the job. yes it is effective one of mine friend did opt for decarb in his 2005 karizma and got wonder results.
the bike was smoothened alot and started giving decent fuel economy.you would also exp. the difference soon after it.
i donot know about the charge.

i would like to know at what price you got the bike. as another of my friend is going for 2nd hand karizma today we saw a 2008 model for 65000

Jithu

Then i will also go for it .. Can you ask your friend what is the top speed he is gettign on it??


i have sent you a private message .
