Unless you damage the asbestos sheet by scraping/scrubbing, the fibers are unlikely to go airborne.Originally posted by SparKot View Post

Re: Karizma/Karizma R
Hi Techies,
I have got my zma's noisy tappets tightened 15 days back. I got it done from a local mechanic since the HH service in Thane is bad and they barely look after problems told by riders and also expensive. The mechanic adjusted with his bare hands. He said he has done it lot many times so knows how to set it to ideal.
The noise is gone and engine is lot smoother now. However, I have noticed popping(no misfire) out of the exhaust recently. The sound appears when throttle closed at 40-60 kmph speed. Is it because the tappets are over tightened? Please suggest.
The AFR is set at 3 turns and engine oil is fresh, Shell AX7.

Re: Karizma/Karizma R
You seem to be running a bit lean or there is a leak at the exhaust/exhaust gasket. Try adjusting the afr in increments on 1/4 turns and check.Originally posted by PTushar View PostHi Techies,

Or sometimes it could be bad fuel causing this.. try emptying your tank out and drain the carb and try with fuel from a different petrol bunk.Last edited by s1d; 05-28-2014, 02:23 AM.

Re: Karizma/Karizma R
First of all i would advice you to get the tappets checked as i think it is the tappets that is causing the problem.Most probably your intake tappets will have been tightened more than required which is causing the valve to remain open for longer duration causing the popping sound.Get both the tappets adjusted as per company specs.Originally posted by PTushar View PostHi Techies,I have got my zma's noisy tappets tightened 15 days back.

Re: Karizma/Karizma R

Splendor Classic front brake pads, 119/- had bought it a month back for ZMA. Still need to source a few more parts to get the bike running, so thought once I set the internals right, I would just ride her to nearby mech and get all the remaining work like brake, suspension, swingarm bush etc done by mech.

Re: Karizma/Karizma R
Popping sound from Exhaust in ZMA is invariably caused by failure of the Vacuum actuator in the SAI unit. Due to frequent movement the rubber skirt ,bonded to the Fresh Air plunger , the skirt and plunger separate and SAI no longer works. This leads to the Popping sound in Exhaust....If you are DIY then you can open the unit and stick the rubber skirt back with Fewi-Quick .... The unit is bolted to chassis under the Petrol tank on the gear shifter side..Originally posted by PTushar View PostHi Techies,

Re: Karizma/Karizma R
Thanks PSR sir. The mech didn't touch the SAI unit since it was evening and getting dark yesterday. However, he has slightly loosened the tappets and asked me to monitor differences. If it doesn't help, we'll check out the actuator. Will update you.Originally posted by psr View PostPopping sound from Exhaust in ZMA is invariably caused by failure of the Vacuum actuator in the SAI unit.

Re: Karizma/Karizma R
You can check SAI unit working by temporarily disabling SAI ,.... by removing the SAI inlet which is connected to the AIR BOX ( Part No 6 in Pict )and put a tight rubber plug to close either the Air Box outlet or the SAI inlet tube and then check.If you are closing the SAI unit inlet tube, Remember to close the Air Box tube also, otherwise dust will get in to the Air BoxOriginally posted by PTushar View PostThanks PSR sir.

Remember the SAI unit is there to keep the Pollution under control, and removing/or bypassing will increase the Exhaust Pollution level...When Was The Last Time,You Did Something For The First Time.

Checked by closing the SAI inlet as well as bypassing the SAI to the engine, the popping sound still appears. Also checked the plunger and rubber valve, it is intact and operating very well. However, after loosing the tappets, the popping sound somewhat reduced but not gone completely. The air filter is also recently changed. Probably my zma gotta live with it, hope she does not create any harm to my pocket in future.
Any more inputs from you are welcome. Thanks for your prompt help.

Re: Karizma/Karizma R
Hi Guys,
Having a problem in my ZMA. Its 8K Kms, 8 month old now, done 4 free service.
For last 2-3 days bike is jerking/missing for a moment on accelerating and while shifting gears upward.
Bike is also not pulling smoothly.
There is no jerking/missing while riding at constant speed.
Checked with SC today, mechanic first changed the spark plug but problem persist, now he is saying he has to check wiring.
I am assuming carburretor or petrol quality issue.
Pl help.

Re: Karizma/Karizma R
Check for Carb slide free movement...Does your bike go above 60 Kmph on top gear ?if engine struggles to accelerate beyond 5 K RPM on top gear, then suspect throttle slide stuck...otherwise check for adulterated Petrol or Water in Petrol...Originally posted by ankit.traveller View PostHi Guys,

If the engine is running very lean then this problem is likely to occur...though invariably it is the SAI unit malfunction 98% of the time. I have no clue what else may be the problem, since I am doing remote trouble shooting....Originally posted by PTushar View PostHello PSR sir,

Re: Karizma/Karizma R
Clean up the fuel tank and drain carb.. try with fresh fuel from a different bunk. And as i mentioned you can also slightly richen the mixture by 1/4th turns and lastly replace the exhaust gasket and check.Originally posted by PTushar View PostHello PSR sir,

If its not the SAI , its probably one of these.. not expensive but just need to spend a little time to do them one by one and check
