However, I feel he should should revert to mineral from the FS Veedol he's using currently.

Sir.

Since last refill i was using castrol activ mineral 10w30. The problem was same at that time also.

I thought the heating problem was due to bad oil and after reading lots of post here i switched to synthetic.

The bike do well at lower rpms but after lots of accelaration when bike goes above 5k rpm heat is emanating from engine and after a long ride i.e. something 100 kms some kind of burning smell is coming from the engine.

Thank you.

If the engine heats up, then it should be the problem with clutch plates.. Like you suggested..

It can be compression loss, say it has gone down a bit from 9.2 to 9.0 . You will difference in acceleration and increased vibrations.
You can get it checked at BIG SVC , ask them to use compression gauge , it should show 180-190 psi as per my calc.
ZMA boring at 60k? Nope not needed , since its 7.5 yr old chances are rings are worn. If needed get new block and ring set.
Run it in for 2-3k kms and then you are free of troubles for next 1L kms .

3 days before i've checked the rpm on 5th gear, the rpm needle was between 5 and 5.25 at 80-85 kmph.

Though i will test the rpm according to margin reference provided by you and upload the details soon.

Tappets are adjusted by mecahnic 3 weeks before by hand. But sometime it makes noise in 2nd gear.

Thanks a lot.

Bike not smoking even at high rpms like 6k+ rpm.

Oil level is at max level.

Bike is 7.5 yrs old and have done 58k+ kms till now.

Thank you.

Most of the things have been covered. Unless it's an engine issue, you could try these two simple things.

1) Adjust tappets to 0.12/0.12 with a feeler gauge and with piston set to TDC. Please do not do this by hand.

2) Basic thing - did you try adjusting the AFR? Since you said the engine is heating up, it can be cause due to a lean AFR and also deposits/varnish in the carb.

To adjust the AFR, turn the AFR screw in clockwise till it stops (don't force it) and then turn out by 3.5 full turns anti clockwise.

Since your bike is not smoking, we can rule out bad/damaged rings or wear in the sleeve. However, the valves might need a polish or need to be reseated (and/or carbon deposits cleared out from the head).

All of these things are relatively easy to do and should be done before you go in for a decision to replace the piston/cylinder block.

Re: Karizma/Karizma R Ownership Experience

Guys...I have observed a new issue in my zma. Many times I posted that there is missing/jerking/misfiring between 4k to 5k rpm on aggresive throttling just after an up shift. I tried many suggestions like slide cleaning etc, but every time issue reappears after some time.

Last time while riding on highway, when missing/jerking started I immediately removed spark plug and installed new plug, to my surprise all missing/jerking/misfiring went away immediately and bike run smoothly till 1500km but again misfiring/missing started, then again I installed new spark plug and problem went away again.

That means there is some stator coil/voltage/cdi/electrical problem which is causing spark plug to short/fail again and again. This missing/jerking problem I m facing since I purchased my bike in 2013. Last year I replaced my ignition coil with new one just for ruling out a cause of missing/jerking.

What is your opinion guys?

I asked a mechanic regarding the speed gaining issue he also suggested me for valve maintenance but before going to final workout expert advice is must thats why i asked suggestion from you people.

I will go to mechanic for clearing the valve issue and upload the results.

Thanks a lot to all who gaved me a valuable response.

Thanks again.

This is a Keihin slide type carb. As you say, you're doing some aggressive throttling while shifting, it means the slide hasn't yet had the time to adjust to the new position. It's hard to explain this, maybe refer to google for slide functionality in a Keihin carb. There is increased throttle response by drilling a hole in the slide, and I believe it's been done within this forum itself. However, it's a risky proposition and you can end up with a ruined carb.

Maybe no aggressive throttling while upshifting will help your issue i.e google rev matching.

Listening to mechanics is a sure fire way of getting your motorcycle ruined. The ZMA/ZMR engines are capable of taking a lot of abuse, but it's better to approach problems in a consistent way and determine what is happening with the bike. Then, solve ONE thing at a time, till the problem disappears, rather than do a bunch of things and then face other induced problems (as has been indicated time and again by Mr [MENTION=32286]psr[/MENTION]) .

Thanks for explanation bro. You are referring to sticky slide common problem in zma? Well, I have cleaned slide twice in span of 5-6k kms after going through psr sir posts. But why after changing spark plug missing problem went away immediately? If it is the sticky slide causing missing then missing should come with new plug also?

I approched to a mechanic regarding this issue 3 weeks before he done the full service and suggested me following on my demand.

1. Air filter is in working condition.

2. Carb. Is tuned well. Idle rpm is 1100.

3. Chain set is in good condition and lubricated.

4. Engine oil refilled is veedol Synthetic 10w40.

Though the above service is done the bike is not going easily 60+kmph and when trying to accelerate more lot of heat is feeled on the legs.

May be it is a time for rebore as my bike has done 58k+ kms. And its age is 7.5 yrs with optimum condition.

Check for water in the fuel tank or rusting which might have clogged the fuel pipe.
I too had the same issue on my previous bike (apache Rtr 160) - bike not moving at the speed according to the rpm and heating up very quickly. Issue was the jets and tuning on my bike. When the mechanic tries to tune it is mostly done in neutral. And it used to Rev fine but once you put it into respective gears the bike used to struggle. I am not sure if its the same issue but sounds similar. I had changed to a new bore, piston, valves, headwork, new clutch plates, chain sprockets, new cam shaft and what not.
I don't think rebore is required.

May be just killing the engine for a while makes the issue disappear for sometime?
And in that sometime, fuel gets time to flow good?

Just my guesses..

Re: Karizma/Karizma R Ownership Experience

Guys,

My Zma is making a weird (kat kat)noise in the engine(cam chain+valves area). The noise comes while starting the engine as well. It is way louder than the kaput tensioner noise we normally notice. SVC guys replaced the tenioner as well. However, the problem still persists. There is no change in the riding experience but noise is so loud I fear if it will cause a serious engine damage. The SVC guys are not able to find the root cause. I have all my hopes from this thread as I dont wanna damage the engine and want to fix it before the monsoon starts.
Mileage: 54000 kms
Oil changes done every 2500-3000kms

Thats right solving the issues one by one is a good way to resolve the problems rather than doing bunch at a time.

Thanks

May be the same problem will be there in my bike as well.

I will let it to be checked by mech.

Re: Karizma/Karizma R Ownership Experience

Guys i found one more issue in my ZMA

In 2nd gear when trying to increase the relevant speed after reducing the speed for bumping the speed breaker or for some other reason engine logs too much and the speed is not increasing suddenly but takes some time to get normal.
