Re: Karizma/Karizma R

While the bike looks good externally, if the engine is damaged or needs work, only a good mechanic (or the ASC) can reliably inform you as to the scope of work involved.
The ZMA's engine is one of the most hassle free engines around, and if you can get a ZMA with an engine in good condition (doesn't matter how many kms it's done), you'll be set.

Re: Karizma/Karizma R

You are absolutely right brother... I got a Karizma with 43k on the odo and the engine is still running smooth.. I did changed air filter to K&N and planning for some performance upgrades.. but the bike it silky smooth.. Bike can easily reach 130 KMPH within a stretch of 150 - 200 mts

Re: Karizma/Karizma R

Thanks for your reply bro
I have one question.Can a bike engine be completly useless because of some damaged unreplaceable parts.
I read in a DIY section about rectifying a messed up engine oil drain bolt.Is there any such chance.?

Re: Karizma/Karizma R

An engine getting 100% useless is very rare. One can always rebuild. Drain bolt getting messed up is due to improper torque applied while tightening the bolt and consequently losing the threading. Ultimately, any more pressure would break the bolt as posted in the DIY. But, nothing to worry, a hammer would save you.
Been there, done that!

Re: Karizma/Karizma R

My friend told me once a bikes engine has been rebuilt it can never be as good as a brand new engine no matter how good the work done, is this true?

Re: Karizma/Karizma R

That is absolute rubbish. What if you have all new parts and then it is packaged by an experienced hand, wouldn't it be as good as a new engine? What do you think they do at the factories? They don't have wizards there.
But generally people replace only the necessary parts, so how can you expect an engine to work like new with some old parts in there? Also some other factors like proper tightening torque for every bolt etc come into play. Still, a good mechanic can do wonders.

Re: Karizma/Karizma R

Depends upon the workmanship. One needs a highly skilled professional for the rebuild to get a near perfect job done. Matching factory finesse is near to impossible but one can get to 90% at least. There are people on this very forum who have done 1L+ post rebuild.

Re: Karizma/Karizma R

@sinnez2000- Whoever said that has no knowledge about engines or have been duped by a mechanic.

Regarding engine re-built then let me tell you that my Joy engine has been re-built two times first time at 1.25 lacs and next time at 2.45 lacs. Now it is nearing 3.30 lacs and still running like charm, The first time my mechanic re-built the engine and second time i with the help of my mechanic re-built the engine.

Re-building an engine is actually not tough but what all parts need to be replaced is what is tough to determine. And believe me a re-built engine performs as good as new or sometimes better.

Actually its not the engine re-built but other parts which damages the re-built engine like chain kit, carburettor, suspension, e.t.c. If these parts are not right then a re-built engine will not last and if these parts are good then engine re-built will last longer than new engine.

Re: Karizma/Karizma R

When the quoted person speaks on the topic himself, I need not give any more explanations.

OT:
sibun da, BTW, I'm still waiting for my dad's bike to get a rebuild lol. Damn, the engine is not wearing out!

Re: Karizma/Karizma R

Man you will get old but that engine will never get old. That will just chug alone. Man the name is not only a Hero but it is actually a Hero, infact all Hero bikes are Hero in real life as they are like those sons/daughters that take every burden of there family without any mumur and are actual hero in life. Similarly our Hero bikes are like that they take every burden of owner without any worry as you get time to spend time with family without caring for maintenace of the bike.

So it is a silent hero which we never realises.

Re: Karizma/Karizma R

Its a darn good engine, I must say. Here in this thread (rather every ownership thread) we keep worrying about cone sets/forks/sprocket sets/head lights/cams/rockers yada yada yada; but I have seen that:
1. Sticking to just one oil brand and grade helps. Any brand and grade. Gulf in dad's case - 20w40 mineral.
2. No matter how recently you changed the oil, draining it within 1600-1800 kms keeps the engine healthy even post 2.5 L kms.

I have been employing the same techniques on my bike from day 1. I hope it lasts at least half as my dad's work horse. Touch-wood, my engine is in prime shape till now.

Re: Karizma/Karizma R

So basically one needs to make sure which parts needs replacement and get it done from a skilled Mech, got it :thumbup:. Thanks for the replies

Re: Karizma/Karizma R

Try out the workshop and do put your feedback here...

Re: Karizma/Karizma R

One other contrast I would like to bring up here to the current topic of factory vs local workshop finish is.. tools used, methodologies followed and quality control.
The factory guys use the torque wrench while tighten the engine bolts and that is a big difference in the run.

Re: Karizma/Karizma R

Hi everyone!
I need help in taking the decision in changing my Karizma R's rear tyre.
My bike is 2.5 year old
has clocked just 14k. (it was hardly used in last 2 years as I was away for studies)

Concern: The stock MRF Zapper Y 100/90 18 tyre does not give me enough confidence on the curves and also, have had multiple bad experiences of the tyre slipping and locking up while braking in wet conditions. I want to upgrade my tyres to a bigger size, probably 110/90 18 or 120/80 18 (preferred as I've used TVS's jumbo 120/80 on my previous pulsar Dts-i and it was good). I know a larger sized tyre would not fit in directly in the small width swingarm so I am ready to remove the chain cover (and take more care of chain later) for a meatier look of my ZMA R.

My need: A soft or medium compound tyre which provides excellent grip and confidence on curves and in both dry and wet conditions. do not wish to compromise on wet conditions. Note: I would love to go for a Tubeless tyre.

Tyres Found available: I have been searching a lot for 120/80 18 tyres (or 110/90 18 as well) but could hardly find much options. some I found were -

1. TVS Jumbo Poly X 120/80 18 (already used and bored of the same tread pattern so dont feel like going for it)
2. MRF Zapper C - 120/80 18
3. MRF Zapper Q - 110/90 18 & 120/80 18
4. Dunlop (the tyre which used to come on old CBZ; seems to be a proven tyre running since long time but I'm not sure of its performance)
5. MRF Zapper Vyde - 100/90 18 (no 120/80 available in 18 but only in 17 inch rims )

Now I've been reading and reading about different bikers' experiences on xbhp with Zapper C and Vyde.
1. Zapper C: read & got mixed responses. and it seems to be a little better than stock Zapper Y in terms of its tread pattern. but some complained that its not so great in wet condition roads.
2. Zapper Q : looks good and is very WIDE , but does not seem to be a dual purpose tyre. So I am worried about its performance in gravels and sand situations (read: our typical Indian roads).
3. Zapper Vyde: seems a great buy. but I want a WIDE tyre! it is 100/90 18 and has a round curve shape so does not look wide at all.

Guidance Needed:

1. can you guys please suggest good rear performance tyres (also apart from above mentioned options) for ZMA based on your experiences??
and comment on the above available tyes??

2. If these are the only options I can have for ZMA, please help me chose.

3. Also, Which are the best tubeless tyres??? [ the MRF dealership owner and employees near Aundh-khadki regoin seemed idiots with no knowledge about soft medium and hard compounds, and blankly said, only stock tyre (Zapper Y) is available in tubeless. ]

4. and is the idea of removing the engine cowl (for change of looks) ok or should be kept for engine cooling performance (if at all it helps!) ??

Help!! urgently as my 2 short trips are pending coz of this stupid confusion! Sincere apologies for the never ending Long post!
Thank you!
