Can the Iridium plug be the culprit?
I want PSR Sir's input here, not regarding what a Karizma has got potential to do, but how is Ashwin's bike shutting off at that point...?

Here's my wild guess. Assuming your cousins still running on stock speedo cable he might be needing speedo calibration i.e if the speedo cable has anything to do with the speed indicated. Mine was replaced a few months back. If you have any doubt then try keeping the bike beyond 8.25K in any gear and after a while your bike'll shutdown

Also, Ashwin bro, you mentioned somewhere (I couldn't collect where) that, Karizma cannot do higher speeds (140+) with the current CDI unit, so do you want to say that if we replace the stock CDI unit with something else, from any other bike from Honda (say VFR 230, doest it have one?

) then the performance will be enhanced???

Yes, I believe so. The current CDI's limiting ZMA's performance to a great extent, its also not zen percent accurate, cause as I've provided before, even since we all own ZMA's each of our bike shows different max rpm ranges. Though I also remember vishnukmd/punarvasu stating that the tacho's not always correct, so thats a topic which is still undergoing debate.

And about alternative CDI's, I've once asked Vineeth bro regarding the BBR Rev Box and he said many rides in Bangalore are using it without any issue. Theres an earlier debate regarding the CRF's CDI being AC since the bike's AC, but I guess thats ir-relevant since theres a high chance the CRF's CDI's DC inspite of the bike being AC, just as in GS150R' case.

Plus, in your pic, FE is written as 20-55 kmpl!!! 55 kmpl???? Are you sure? When and how? Elaborate. :O

The FE of my bike's still a mystery. My least mileage is actually below 20Kmpl, but I dont post it for the sake of respect towards my ride. And regarding the 55Kmpl, its not exactly 55Kmpl, its a round up figure. I travel to college daily to and fro, one side distance is abit over 40Km so total we can say 80Km's. And daily my travelling budget it 100rs, with the petrol costing, 68.20 I get about 1.47L, and with that am able to cover a total of 80Kms, meaning 80/1.47=54.9 Kmpl, (due to constant change in fuel costs am abit confused, cause at the last exact time I checked it, it was 56.xxKmpl).

Sorry, couldn't read all posts due to lack of time. I'll be back to xbhp from 20th onwards. Happy riding.

I don't know either, this is how I did to find neutral during my long road trip. At times it was difficult to get the Neutral, so would release clutch just a bit and it falls right in place and green on the console.

Are you sure you're not calculating this on a weekly/monthly basis?
What I'm trying to say is:

Suppose monthly expenditure on petrol is Rs 3000, i.e. Rs 100 / day, but actually you're not going to college all the 30 days! So, if that is the case how you've calculated your daily fuel expense then obviously it is wrong and you have to calculate how many kms you exactly traveled and how many litres of petrol were filled.

You are definitely not filling Rs 100 fuel daily and then running 80 kms, are you? No, then please next time when your bike hit reserve, do post here for how much you filled and how many kms your bike ran before hitting reserve again, as simple as that!

Yes Sir, that works on most bikes.

And regarding that "positive neutral finder" thing, please refer Positive neutral finder?

Will it be exact 80 kms when you hit reserve? You hit reserve when you reach your home?

**shubhamAT** · 01-06-2012, 07:36 PM

I did try the clutch-release-pull method of finding Neutral and it kinda works for me. I am able to get N from 2nd quite easily now. Does not work from 1-N though. May be i need little practice.

Also, not to sound blasphemous i feel Apache 160 (carb) seems to have better pickup though the first 2 gears than my ZMA. Is it true ?

1. Similar from 1 to N also, just a slight nick-of-tap needed with slight release in clutch.

2. " i feel Apache 160 (carb) seems to have better pickup though the first 2 gears than my ZMA" I don't know about your ZMA, Sir

, but what I can say is:
Maybe you felt this due to the weight factor, but if we launch the Karizma correctly in first gear, even R15 won't be able to catch us till atleast 60-70 kph!

Ashwin and his bike are one of a kind....his young & new bike had already seen the bore, piston etc., changed...so i am at a loss to explain the specific phenomena.All I know is that ZMA has a rev limiter in it's CDI set at 9K + RPM. I don't think anyone would have tried so many things on their NEW bike as Ashwin had done on his.. That said a Karizma on 5th gear can never reach the RPM rev limiter ,unless there is a clutch slip.So if engine cuts off at 8+ K RPM there could be other issues,including the spark plug.
The HH ZMA is a copy of Honda CRF ,but the CDI and it's functioning are totally different from it's Ancestors.

About the relation between the Lag and the Iridium which discussed here a few pages back, yes I do feel it too..

I have fitted Iridium in my ZMR, and since then I could not go above 120kmph how hard and which method I try.. Are these factors relate each other??

**shubhamAT** · 01-06-2012, 07:56 PM

@sunny: Will practice more for 1-N. Might be due to the light weight that i was perceiving speed more in Apache.

It is possible that the thin electrode is not able to build a strong enough flame kernel at higher RPMs,like the stock plug.When I had the side gapped plug I could easily touch 120 kmph....I am presently on a G power with smaller sized electrode, and found it to be good at RPMs below 6K...When i take the bike on the highway I will know for sure.

Well I got the same feeling when I rode an rtr 180

. Bike zooms like a bullet. Don't worry mate its only a feeling. ZMA always feels lazy but the bike pulls off and you won't even feel it. I realized this when I had a dog fight with an r15. I could see him as a dot in my mirror and my bike was already past 120 kmph

.

If I get 3k per month then I'd be the richest teenager alive, I get 100Rs per day, i.e for food(50) & bus(50) fare, but since am lazy to catch the bus(have to walk 2 kms) I usually take my bike to college. The exact distance to college is a bit above 40km's not much just x.1x or x.2x so am not considering that.

Nope, I hit reserve near that hotel owned by Madathil Raghu. Everyday the same spot +/- a few meters.

Right on, if launched 100% perfectly then nothing beats the ZMA in a drag, not even the RTR180 or P220. But the thing is you need balls of steel to pull a feat like that, cause past 5k in 1st gear the torque is so much that we feel like the insides of the engine are going to rip apart and we get scared and back out. Mine was normal with stock plug, but the iridiums have a slight lag so when we whack open the throttle for a millisecond there wont be any repsonse, then all of a sudden the bike drags you to a wheelie, once it caught me unexpectedly and the result was a torn ligament in my right leg.

Yup Sir, me and my ride are special .
And haters can hate all they want, but at least when my riding days are over, I can proudly say....
BEEN THERE, DONE THAT!!!

(There is no mandatory rule that the below information should be considered, if you want it take it, else leave it, cause am tired of the long senseless process of "B-ing".)

Have been thinking, and I've got another wacky theory.
Normally there are two types of limiters right, physical and electronic. What if the ZMA had both.???
1. Electronic - My bike's proof that the electronic limiter exists, cause as I said, be it any gear, post some time in the 8.25K mark and the bike dies.
2. Physical - Suddenly rip the bike in 2nd gear and the bike nearing the 9.6K mark just hits the brick wall, there are no RPM bounce backs.

Have'nt faced any issue's with high end yet. At first when my bike stalled between 125~130Kmph I doubted the iridiums, but when another guy also reported the same with his ZMA(Pure stock.) then I understood it was common be it iridium or stock.

But I'm facing issue with initial pickup, the smoothness is lost to an extent, when we drag the bike wont respond for a few millisec's but when we're off guard its like WHAM!!!, the bike pops. And I'm 100% confident its the iridiums, cause when switched back to stock for trial, the issue was gone.

First of all please don't use bold my eyes are getting sore.

Beating an rtr 180 is ok but I don't think you can beat a 220 on a stock ZMA not at all. Even if you ask rossi to do it.

. There is a chance if you are dragging a 1+ year old 220 or a not properly maintained 220 ( the thing is majority fall in this category

)

I hope when you were typing this you already knew that RTR180 kicks P220's ass in a drag???

Maybe on paper P220 rules, but on the track, the RTR180's the quickest Indian around.

**shubhamAT** · 01-06-2012, 08:55 PM

the insides of the engine are going to rip apart and we get scared and back out.

Exactly!. However 3rd gear onwards there no drama. I had my first ride in heavy flow today on OMR. Overtaking three wheeled parasites was a breeze. I rode carefully never ripping the bike though i did get to 5th on 40+ speeds. I am shifting around 3.5K mark. Is it right ? RVMs some how dont look adequately sized to me.

I guess i may need few tips of riding the bike from you guys now. As there are numerous speed breakers on my route to office, some less than 100m apart, what i am doing is as i about to touch the hump i quickly shift to 1st (speed is about 5 till this time) with the clutch pressed just in time to prevent knocking and then tackle the hump with the clutch still pressed. Riding the bike in 2nd gear between the humps looks like putting undue strain on the engine that is why i shift to 3rd.

Is it right ? I guess not. But how would one tackle short spaced humps then ?
