What I meant was, this is a bike and it cant recover over time. In simple terms, you've kick started the bike 10Months before, what say if the damage happened then... or worse.... the SVC guys have misused the kicker even before the bike was in your hands. So that doesnt validate that there might not be a chance of your decompressor going kaput since you havent used the kicker in 10 months.

Sir are'nt the above conditions the same???
The decompression mechanism in the cam, causes the exhaust valve to remain open, right???
So that means moving the bike in gear will cause the cam to rotate and disengage the decompression mechanism, thus helping the bike to regain compression.???

I've heard of dead kicks , but only connected with old gen ( read that as RE or Yezdi) bikes . But I guess it's OK for ZMA . BTW should the clutch lever be pulled in while doing this is something I'm not sure of .

Some people tend to literally KICK the kicker, and its wrong, it should actually be gently pushed with the leg. If instead of gently kicking, the kicker I would've kicked hard like some people do, instead of the kicker seizing, it would've kicked back and gave me a hyper extended knee. So be careful.
the kick starter is supposed to be gently but steadily pushed by the leg.
+1 . In smaller cc bikes it doesn't matter to a layman . But in bigger cc bikes it does . Even Bullet can be started without any strain to your muscle if you know how to do it . Actually you can start it with your hand !!
In the beginning I didnt know about this, and I believe thats what has resulted in my decompressor going kaput.
It's never too old to learn !!!

Query

Am I running my Engine at Right settings?

That's for you to decide . In a general way , 3 - 4 turns out is considered optimal . You may vary it as per your bike's condition and as per your needs . You can go upto 4 if you're rev happy/economy go to hell type of guy or you can go below 3 turns if what you want is mileage at the cost of smooth riding comfort and power ( see Ashwin's sign).

4. Now turn the screw ANTI Clockwise by 3.5 full turns.
This is a starting setting.If you have hesitation in acceleration with cold engine till 1 or 2 Kms it is ok, but after warm up ,if you continue to have the hesitation as well as the engine turning off when accelerating,turn the AFR screw another HALF turn ANTI CLOCK WISE....this should give you near perfect setting..
That setting will give you decreased mileage as well . But you'll enjoy the ride !!

Nice to have you back after a short break sir .

Murphy's law - if anything can go wrong , it will !

. In the meanwhile , enjoy the best sports tourer in the country .

BTW , my 235 ZMA-R hasn't given any trouble so far . Have ridden only about 150 km since the heart transplant . The in-gear acceleration is pretty good . Have gone up to 5k rpm on occasions - mainly just to experience the raw power !!

For sure SVC guys had not done funny since it is always serviced right in front of my eyes. Well, there might be some manufacturing defect or even something was done to my bike before took delivery then. Anyways, thanks to my bike that it had always supported me till now for all my tours. Less worried, munching more miles thus earning more smiles!

Hope you complete your runin soon. Would really love to know the difference in top end.

Thats the way it should be. Ride safe.

@ACS Sir,
What's it with the clutch being pulled in???, in the ZMA the kicker moves freely when the clutch is pulled in i.e in neutral.
The dead kick I was referring to was just by turning over the engine, till the pistons at TDC. In my case if I want to turn on my engine its mandatory to do dead kicks, else the bike wont start this is why I suspect the decompressor to be faulty.

No difference is expected in the top end since the gearing is not changed . Well , there may be a slight increase due to the increase in the ability to push the final drive to the max . Without sprocket-ing , there won't be much difference in the top end . The pick-up/roll on times will show a difference though .

Yeah, want to know how much into the red zone the bike goes in final gear before the engine stalling. So that sprocketing can be done in respect with that, hence you can get a higher top speed, with the same stock acceleration.

A ZMA crossing the 150Kmph barrier on GPS would be a dream come true.

But there are other factors to consider such as the transmission holding up to the added pressure from both ends etc.

And about the CBZ cat-less pipe's have a narrower bend pipe than the ZMA, also take that into consideration while going for it.

And sir, please read the last part of my previous post regarding the clutch being pulled in while dead kicking.

Do you think a Karizma will be stable at 150+kph if other parameters are kept stock, I don't think so. "not safe"
moreover, the brakes are not "perfect" for speeds above 120kph, so we MUST think about how the bike sheds off speed while braking once it is traveling at such high speeds, before dreaming about it crossing 150kph mark.

@ACS Sir, congrats that your mod found the practical way finally.
General details like acceleration timings, max speed per gear and FE would be appreciated

Are they the same ? if moving the bike in gear will actuate the cam so will the self starter or the kick starter...
The Kick starter is there to start the engine ,and no abuse can possibly harm the interior of the engine through this, unless you ride around with the kicker pressed down.
There is an internal technical note in Honda about the sticky throttle slide and sticky valves .Google and you will find it.

Happy to note that your mod is working without hitch so far...Normally you shouldn't face any probs, but to be on the safe side,when you are taking the engine to above 5 K RPM, listen if any strange sound comes from the engine ,and back off throttle if it does...

Do not go for sprocket changes...as it is the ZMA has 0.8 ratio in top gear,which is the tallest amongst the class..
Good luck to your bold experiments

Sir, then I guess the something else has messed with the decompressor in my bike.(Hope you've seen the video I've posted.)
And another thing I've noted is that, when my bike was new, whenever I turn of the ignition, I hear a gunshot kinda sound, but recently it only happens once in a while like 1 in 5 times. Is that gunshot sound, the sound of the decompressor working???

Yeah, but most of the articles are related to cars. According to google there are'nt any CRF230 owners who've experienced this.

Without sprocketing top speed would still stick at 125Kmph.
Guess the acceleration difference is what matters when doing this mod.

@Acs sir,
Please do post the 0~60 and 0~100 timings after running in.

17k is too high u can always get the swing arm frm the junk yard here and rtr pads will do...might cst less than 4-5k for tht set up including labour

update on tyres
yday went to a very known tire shop here and got changed to sirac street on my frnd's unicorn as the stock tires were done above 40k +.
GOT SIRAC STREET 100/90-18 for 2200 wit tube and
sirac street 2.75-18 for 1800 wit tube total cost 4000 wit fitting and got 300 for the old tyres and tube as it had 7-8 punches and 2 paches in rear..
psd 110-80-18 was quoted at 3000.
planning to put 1 b4 rains...

any one here tried MAK NXT oil...want grade does it hav saw one at a shop bt it didnt had any grade written on it bt it is semi synthetic for sure ...and it is also meets API SL performance and requirements of JASO-MA2 standards..

Hey guys...does anyone know about whats the cost of the brake pads of Karizma?

Just checked out the list of spares on ur site, one in ur signature, it shows price of RTR pads too. So that means its a direct fit for ZMA? If so, how good are those?

Please use Search Option,Already Discussed before.

Nissin pads may not show heat fade and will last longer,whereas the RTR pads may wear out faster...Apart from brand value, the material used for the pads also contribute to the cost..
