Re: Bajaj Pulsar 200NS to get Fuel Injection?: xBhp News

Chill guys, sorry for bumping this thread and create a debate, don't fight, after all, we are a community and we look for each other.
See, I'm Dying - AR15.COM how an online community is helping a member in need. A guy named Dave donated $8,787 and Timothy donated $1,000 Again, motoGP bike builders are concerned about FE as there is limit on the amount of fuel that can be put in the tank and FI does improve throttle response resulting in better handling and with better fueling, improves the smoothness of the engine, also less carbon build up. All at the cost of 10k (estimated) rupees more.

[MENTION=65188]raging_bull[/MENTION]: i used puc word as a shortcut to mention emmission norms as i was typing from mobile...

And yes i am also saying the same thing that fi has many advantages.. However payeng said that its only for emmission control and cold start...

Re: Bajaj Pulsar 200NS to get Fuel Injection?: xBhp News

The Major Benefit is controlling Pollution (as set by Govt. regulations and for cars its currently impossible to match it with carbs without going for Fi), the Tangible benefit is in cold starts..

Increase in performance? Increase in Fuel Efficiency..?? Could be, but by what margin? Seriously, I have never felt it. Specially when you pay around 15-20% more for the vehicle's cost.

The P220F Carb. is faster and equally fuel efficient (if not more) than the P220 DTS-Fi which used to cost about 15K more.


Having used Fi on my P220 DTS-Fi and using the tech in my car, I would definitely go for "Fi" even at 15-20K premium.. but only for the hassle free riding/driving experience it provides and NOT for dreams of getting dramatic jump in power or mind blowing fuel efficiency (which it doesn't).

Re: Bajaj Pulsar 200NS to get Fuel Injection?: xBhp News

The point isn't the level of change in performance in FI vs carb, the point is that there is change and that is undeniable. Ofcourse, this happens if the state of tune is similar in the FI and carb variants of the same vehicle including that the gearing or any other parameters remain same as well. The carb P220, I believe, is in a slightly different state of tune than the FI variant; also, the carb P220 produces slightly more HP as well and hence it performs better than the FI P220.

Otherwise, ride the Karizma and ZMR back to back to know that the ZMR is overall a better performer in all conditions. Similar is the case with Stunner FI and Stunner carb. That marginal increase in bhp and performance is because of FI, where otherwise, the motorcycles are in similar state of tune. The biggest purpose, other than eliminating cold start problems, is to have as perfect fueling as possible. The FI will always achieve this better than a similarly tuned carburetor.

And this isn't a myth that people are led to believe!

Re: Bajaj Pulsar 200NS to get Fuel Injection?: xBhp News

But definitely not dramatic levels of "improvement" as people believe it does. For those who have not ridden Carb and Fi models of the same make back to back.. It is mostly a Myth.

I have ridden the Stunner Carb and Fi back to back. Wouldn't say that the performance of the Fi is better.. but it definitely feels better to ride.. which is also because of the characteristic vibration at around 60 kmph that both the carb. Stunner and the Shine suffer's from is/was absent on the PGM-Fi Stunner.

Fi is tuned differently than a carb. It is much more elaborate process involving a lot of electronics and sensors and therefore expensive. It is tuned it at every stage of the ignition curve, whereas a carb is a simple mechanical device.

The Fi tuning process has to be precise and perfect else one can end up like the first Hyosung GT650R models launched in India which had erratic Fueling issues (don't know if the latest ones are rectified).

Re: Bajaj Pulsar 200NS to get Fuel Injection?: xBhp News


True payeng, definitely not dramatic if vehicles are overall in similar state of tune with respect to cc, bhp, torque and gearing....like in ZMR and ZMA

Re: Bajaj Pulsar 200NS to get Fuel Injection?: xBhp News

Payeng bro.. U r missing the point...

Commuter bikes (read small engines) = Carb (cost being the sole reason)
Sports bikes, cars etc (read big engines and cost not an issue) = FI

200NS has a single cylinder engine. Most of the bikes mentioned here so far also have small, single cylinder engines. I repeat, it's difficult to see the difference in such cases. But saying that this is the case everywhere is nothing short of ignorance. For eg. CB1000R has a 1000cc engine with 4 cylinders. If you compare the technologies on such an engine, the difference will be clear.

And we all know what FI has done to diesel engines . So folks who say that FI has no tangible benefits please add the phrase "on small engines" or try not to generalise their point of view because that can be highly misleading. FI may be unnecessary on the 200NS but that ain't the case everywhere.

^^ very true .. And those who disagree can click wikipedia..

Re: Bajaj Pulsar 200NS to get Fuel Injection?: xBhp News

so guys who want FI on NS I have a question, Basically you would pay 15k more than current version just to have FI on ns considering there won't be major difference in performance or fuel efficiency?

Bajaj had a product with Fi and it then promoted sales of karizma. So bajaj discontinued that product. Now bajaj has a successful product on their hands with triple spark with carb which has been known for being more efficient than its FI twin and you guys would like to have bajaj to act stupid (again) to scrap that tech and go for FI to create a niche model which won't be any more profitable to company.

This reminds me of another debate not from long ago. DOHC vs SOHC. Many came around wearing smarty pants and started saying R15 2.0 is dead as CBR150 has better tech and one more pony in the engine. Today, I still don't see a lot many CBR150, hell, they are even rarer than CBR 250, where I live. But R15 2.0 is omnipresent.

I'm missing something, please please please please enlighten me how FI ns is a good thing from both customers' and Bajaj's point of view?

----consecutive posts auto-merged-----

--------- [MENTION=10465]payeng[/MENTION]: can you tell me how triple/double spark tech saves silencer? I'm really interested to know.

Re: Bajaj Pulsar 200NS to get Fuel Injection?: xBhp News

Exactly.. very few according to me, provided it doesn't have a Full Fairing strapped on it.


I presume you must have checked a 1000cc 4 cylinder Motorcycle with carb and also a 1000 cc 4 cylinder Motorcycle with Fi (back to back) to be making that statement.. since honestly I have not.

When did Diesel engines ever have Carburetors..??

Re: Bajaj Pulsar 200NS to get Fuel Injection?: xBhp News


What FI twin?

Re: Bajaj Pulsar 200NS to get Fuel Injection?: xBhp News

We don't have to drink poison to know it's poisonous. With EFI you have injectors for each cylinder. Fuel delivery can be controlled for cylinders individually. This of course has many advantages. Edit: This easily explains why a single cylinder engine is not the ideal example for comparing FI and Carb. And the sensors used help adjust the fuel supply and thereby help achieve better combustion. That's why FI systems don't need adjustments for altitude changes(generally), unlike a carburetor.

Generally, the bigger the size, the easier it is to note the differences. This is common sense. Please don't argue on this too.


Back in the ooold days diesels had carbs. Don't wanna write about it since it's OT.

Payeng buddy, you are fighting a pointless battle here. We've already reached the conclusion that using a FI system on 200NS is, to a certain extent completely pointless. And that's the topic of this thread. You are trying establish that the whole FI system is stupid and that it doesn't make any difference to the rider/driver at the end of the day except smooth riding/driving and easy cold starts. And I can tell you, that 'smooth' feeling is what makes FI so much superior and, performance gain, better fuel efficiency, lower emissions etc are the byproducts of that 'smooth' running. I also wish to point out that lower emissions basically mean better combustion and we know what advantages it has. The whole auto industry knows it, uses it and one 'payeng' on xbhp refuses to agree. Well, I don't see any point in continuing this debate.

BUT what I don't want to see is some MOD deleting our posts and marking it as 'unnecessary' or 'OT'. It was a necessary debate and it definitely helped us reach a conclusion.

Re: Bajaj Pulsar 200NS to get Fuel Injection?: xBhp News

And how long back were these Good ooold Days..?? The credit of starting the "OT" belong to you.. own it.


The "Whole" auto (motorcycle) industry started and came back to carbs.. well not all (Bajaj, TVS and even Honda did.. with the stunner).. some still continue with it (Hero, Yamaha and Honda).

The "Whole" car industry have to stick to it as there is no option but to go for Fi.


I am not against "Fi".. its a modern tech and definitely the way forward.. In fact I would choose a model with Fi than a model without Fi.. even at 20K premium (and with no full fairing). I am just amused at the guys who believe that "Fi" would boost performance and fuel efficiency like magic.

Re: Bajaj Pulsar 200NS to get Fuel Injection?: xBhp News

200NS with FI and ABS is already there, they are just not available to Indians. There should be both version, one with FI and ABS and the other with carb and without FI. The best I can suggest.
