Re: Karizma/Karizma R Ownership Experience

Hi,

Anyone here using or used the 8Map Racing CDI from NMW Racing ?

Re: Karizma/Karizma R Ownership Experience

New year wishes to all xBhpians !!!

This thread has been dull for quite sometime.

I have been hearing some rumours on the launch of old model Karizma-R and ZMR.

Not sure how far its true, but I have heard it from ASC guys here in Chennai.

Any information on that ? Have anyone come across any news on the old model launch.

Would be more than happy if this turns out to be true.

Re: Karizma/Karizma R Ownership Experience


i dont know its true or not some youtuber posted this on his fb page hope its true

Re: Karizma/Karizma R Ownership Experience

Wow Jet set go

Thanks!☺

Re: Karizma/Karizma R Ownership Experience

Thanx Alot [MENTION=47074]Divya[/MENTION]_Sharan

Re: Karizma/Karizma R Ownership Experience

might be:
1. new bike from old stock
2. well maintained/less used, with a new crash guard
3. don't be surprised, i've seen folks who don't register their bike even after a year (some even more) around here in Hyderabad!
4. Or a restored motorcycle , going in for change in regn # from other state etc..

[MENTION=51034]ankit.traveller[/MENTION] : Hope you are having a good time with your ride !!

My ZMA has slowly started showing symptoms of the issue that you exactly faced on your ZMA - missing / jerking between 4k to 5k RPM.

The power loss / sudden missing is felt only when for harsh throttle inputs from rest and does not occur when I am already at top gear (cruising at less than 4k rpm) and start reaching 4k + rpms slowly.

Had been living with this for almost 3 months now.

Its getting worse day by day, as this issue creeps in even with a little hard throttle input.

Can you detail on the particulars that you have replaced ?

I have attached the page from spare parts catalogue for reference.

Thanks in advance !!

Re: Karizma/Karizma R Ownership Experience

Hi folks, need some precious advice. I have done 50k plus kms on my sept 2013 zma which includes 70% touring including recent ladakh trip in sept 2016. Till now engine/head/clutch never been opened and using shell ultra fs every 2.5k kms but after ladakh trip I am feeling and hearing roughness vibrations and strange noise from engine, upon consulting with ASC and an experienced private mechanic, they both diagnosed that there is piston noise/knocking/slap and new block piston is required. Note that my engine is not consuming oil too much, since last oil change i have done 1500 kms (mixed riding) and oil level is full in dipstick. Both mechanic saying that due to piston slap, cylinder will start wear out soon in future so its better to change block piston kit.

I had ridden almost 2k kms with wire in main jet mod to overcome altitude problem during ladakh ride. Even after returning home i forgot to remove wire from main jet and ridden few hundred kms. Is this the main cause of piston damage due to lean mixture and overheating?

Please suggest should i go for engine rebuild and keep zma for next 2 years or purchase a Dominar 400? My whole touring is on mountains and high altitudes where zma lacks due to its afr default settings. In zma either have to put wire in main jet or remove air filter to overcome altitude problem which have major side effects. During my ladakh ride even my buddies stock unicorn and apache was pulling effortlessly on high altitude but my zma was seriously sputtering and misfiring and was not going above 4k rpm before wire in jet mod.

In some other forum i have read that making few holes in air box cover (lid) overcomes altitude problem upto acceptable levels without damaging engine (can close these holes with duct tape when returning to low altitude) but i have not found anyone have tested this mod in india and reported. If this mod is possible in zma then i will keep mine for next 2 years for spiti, zanskar, sikkim ride. Free flow air filters are also a solution but this also damages engine in long run afaik.

Hi bro.....i replaced throttle grip (part no-12) both throttle cables and problem vanished immediately but to my dissapointment it came back again after 2 months. But during my ladakh trip when i put wire in main jet then again this problem vanished and till now never came back. I think there is some serious quality issues in last lot of zma.

Re: Karizma/Karizma R Ownership Experience

If there is no oil consumption yet, you can wait. Just get the head decarbonized and get new rings. Also, see if the tappets are adjusted right with a feeler gauge only.
You can try adding Nulon to the oil to an extent if piston pinging increases. 50k is too less to be honest to warrant a bore change if the bike was maintained well.

No need to permanently damage the air filter box. You can just remove the snorkel located under-seat (attached to the air filter box). It causes no harm at all and many people have reportedly done that. Phanikar sir had also suggested this as a possible workaround in one of his threads and yours truly has been running without the snorkel (on a ZMR that is) for years now.

Re: Karizma/Karizma R Ownership Experience

Running lean for long can cause damage, suggest to get compression tested.

Re: Karizma/Karizma R Ownership Experience

Divya bro which is the best method to decarb ? I mean combustion chamber, camshaft, rockers, piston head to be decarb seperately with diesel?

Desnorkeling also work but its a permanent thing , while returning to lower altitude it will lean out mixture in carb but in your case fi will adjust mixture accordingly. During tours it will be difficult to put back snorkel back coz whole air box to be removed for this whereas air box cover holes can be covered easily. The whole idea is to increase air volume and velocity going to carb. Correct me if wrong.

Curse bhai how are you? I hv lost your number. Pl pm me. Will get compression test today.

Re: Karizma/Karizma R Ownership Experience

I meant just remove the soot from the top of the piston and clean the ports and valves.
And regarding snorkelling/de-snorkelling, only the seat needs to be opened. It's just plug and play. Air box need not be touched.

Re: Karizma/Karizma R Ownership Experience

[MENTION=41586]Divya Sharan[/MENTION] : Just a quick question bro.. The smell from the exhaust seems to be so unpleasant and it gives an impression as if the combustion is not proper.

This is felt at all times and not only during cold starts.

Had been running on NGK G-Power for close to 4k kms and changed to the NGK OE plugs about a month back. But this issue seems to be present since I purchased the bike, when the Odo was @ 28000 kms and presently it is at 36000 kms.

Owing to a sound in the engine bay, I got the bike checked at ASC and got the cam chain tensioner kit replaced at ASC recently, which was about ~800 kms back.

Still there is some other sound seen, which I am not really sure about. No drop in oil levels seen.

Are these symptoms related to the issue that you had posted by any chance ? I am not sure though.

Seeking your advice.

Thanks in advance !!
