That video was quite explanatory . In my bike the choke doesn't jump back like that ( 100% sure ). But when I checked today morning I noticed on thing, when we push the choke lever back to close it the choke lever moves with far more less effort than pulling it to open it. So I think due to constant use or a loosened lever Ashwins choke pulls back automatically. Whereas my choke lever doesn't go back the reason is too much friction between the lever and the fiber thing just before the handle grip where we connect the mirror and pass switch etc are placed ( sorry don't know the name I hope you guys understood the thing I meant ). With constant use I think it will smoothen out and choke lever starts to jump back like that or else its some kind of defect.

How can you spoil the Iridium by taking it out - unless you are that sloppy ??
Is there a minor lag when compared to other ZMA with normal plugs ? I haven't noticed any particular lag - other than the one that comes with a long stroke bike . I think what you've mentioned is typical of long stroke bikes .

Now , that is something I've to see to believe . To my knowledge turbo boosters for small capacity engines don't exist currently . Even if you can fit one I'd seriously suggest decreasing the engine capacity or modding the entire chasis setup along with a rear disc conversion .
Well , may be you said it in a light mood . But I think some sort of super charging is possible . ( My friend once retro fitted a turbo to a Contessa - diesel - said he enjoyed it when he could leave 'powerful' cars behind him ) .
@ashwinprakas-The popular opinion seems to be that 'your' bike is/may be defective . Next time at ASC check whether any spring/stopper is missing or broken .

Sorry for the late post

Day before yesterday I had a short trip of 450 kms. It was a one day trip from my home to Ernakulam and back. Went to see my GF .

I set out at morning 6am and the got quite an opportunity to test the top speed of the bike. There was no traffic and I opened the throttle and leaned down on the tank. The top speed is some 128 or 127 kmph (The needle was a tinge below the 130 kmph mark). The road was flat, no wind factor and what I said is the speedo reading. The bike easily pulls till 120 and then moderately to the said top speed. Got a feeling that the bike can even do more but its lazy.

During slight crosswinds at speeds of 110 kmph the bike tends to be unstable. I was travelling at speeds between 85-100 kmph most of the time. Bike is quite comfortable in that speed range.

What impressed me the most was the impeccable handling. The handling and stability is the best. Wherever I want the bike to go it just obediently goes there. And cornering its good too, I was satisfied. Can't lean too much but still quite satisfactory.

I filled 10.32 liters of petrol (normal petrol) and covered 394 kms. The suspension is good but the bike tends to dive when applying brakes. The front suspension needs to be bit more stiffer (wish it was adjustable too like the rear shocks ). Riding over potholes and speed breakers was comfortable.

The little disappointment was when cars overtake me even while I was at speeds of 100kmph. And all the trucks and cars doesn't bother to dim the headlights . And it was easy to overtake vehicles the bike can easily pull ahead with just a twist of the throttle. Good acceleration even when after 90 kmph.

And above all my GF said she loved to sit on the bike and it was very comfortable . That comment made me damn happy. I set out back at 7pm and reached back at 10:30 pm .

I am using SAE90 oil for lubing the chain and almost after covering 250 kms at these speeds the chain started to make noise. The oil is good for city use and not for long hours of touring, better shift to grease. Or else have to carry a can of oil along.

The helmet was a total piece of sh*t ( vega moto cross model) . Really it was paining my head and the visor was a total pain, causing a lot of glare . Honestly 1600 rs gone waste.

The headlight was good on both beams (55/60w). Not the perfect one but still its anyways better than other bikes on Indian roads. When vehicles come on opposite direction the light is not so good but when alone on road its awesome. Even in rain you can see the road .

Checked the reflector for any burning issues today morning. Well very very minor issue . For those who want to use 55/60 as headlight try using bosch 55/60 without relay. I am using this brand and relay might increase the output so better don't. Just put the bulb in the stock relay.

Overall the bike is worth every penny I paid and of course the 20w 40 is the best for touring. The bike had its refinement all day long .

Ashwin yesterday and to-day I had been exploring the Auto choke return symptom you had noticed....My bike has this..ie., the choke returns to rest automatically when I let go of the lever and my ZMA is 2007 April.. I tried the same with a friend of mine's 2008 ZMA and it was stuck in actuated position,till it is pushed back...when I opened the left switch assembly and checked the choke lever, the one Marked difference was a steel ball with spring in the choke lever which was missing in mine.....Since my friend wanted the "Auto-return" choke, I applied heat on the steel ball (with soldering iron)and removed it and the spring , and now the choke lever is auto return....

So the stock choke lever has the ball while the ones opened and closed may not have it....Here is a picture....

Wow sir, so that means its actually a flaw.

Hmmm... Anyways here's what we'll do... Lets delete both our posts, and claim the rest of the bike's are damaged . But jokes apart, my switch assembly is still untouched. My choke used to retract from the first day of purchase. When I noted that Aneesh's doesnt retract, I remember checking it with other bikes at SVC during first service and all bikes from my batch had auto return. Thats why I once again claimed all 2011 ZMA's to have it.

And comming to think of it, its not a big flaw, infact its an international innovation, IIRC N250R's had auto retracting choke as opposed by the earlier versions which had choke that stuck.

Anyways its good HH people didnt come to notice it before us, if they had then they'd surely print it in their brochures. Does any one remember the 2011 ZMA's brochure stating that the new model has all the new Red Colored Distributor Cap.

Can't say that....HH might be saving the cost of the ball and spring, and also getting auto return which will ensure users don't ride with choke "ON",and report poor FE and bad bike performance. In our country More people handle other people's bike while waiting ,or on the mobile ,or just having a smoke..ie., you would have seen them twisting the throttle,actuating choke,brakes etc, also sitting on it,...and most irritating thing of all,adjust the rear view mirrors to see their face and do hair styling..
In such circumstances the auto return of choke is a boon...

Amen . Could'nt have said it any better.

Sir, you're right about the opening of switch assembly, take a look.

Choke Lever Problem - Won't stay open, springs back

rev limiter


Ashwin, Could you elaborate on the rev limiter. Sorry, if its been discussed before, I must have missed it.
I recently rode from Mumbai to Banglore (around 1000 kms) with speed mostly above 110, not once did the bike stall or give any issues as such. Mine is a 2010 model and had completed 20K kms then.

Rev limiter on Karizma comes on about 9K+ RPM...

installing hid to zma

hey guys can i install hid bulb in my zma without projector will it affect my reflector plzz help me with ur rep

Come to think of it, my bike never went above 8k (even if when tried)

You cannot touch Rev limiter RPMs on 5th due to taller gear ratio,but in 4th you can..though I wouldn't do it..

Like every ZMA owners, I had an issue with cracked front mudguard and side panels. I had tried using feviquick, but it would not last.
With the advise of one of my friend, I filled the cracks with feviquick and cotton. It has held strong since, even through the pothole filled NH66.
Has anyone else ever tried the combination of cotton and Feviquick before?
