@lockhrt999 and @Cleaner sirs please include me in your knowledgeable discussions as well and make me your "shishya" so that I too can learn about the engines and stuff and I like to get my hands dirty irrespective of the intensity of dirt coz It rarely happens that we get to interact with people like you (both) who are really knowledgeable and down to earth (its seen in your posts, the language you use... ) and hats off and claps to the way you've sorted out this matter, talking like Educated Adults and matured people sharing knowledge and understanding things coz I have read posts here itself where people are like "bahar milna zara... ham phir toka dikhaib ki ham kaun ba..." (referential context U.P. Ishtyle...)

I don't understand why people don't understand that its a place to share thoughts, ideas, knowledge, help and grow... ELEMENTARY Stuff...!!!

Its really commendable that the knowledge you both possess, especially you @lockhrt999, had I been living in any of the same towns as you, I would have taken regular tuitions from either of you or both would be best...

SO Guruji Guruji Kakshayein kab se chalu hain...???

Cheers to Knowledge and Education... and of course P180 (how can we forget her...)

Oh let it rest already, I was in the schools when it came out and I didn't even know if it ran on petrol or diesel at that time. Everyone said it had kawasaki engine like the eliminator which was launched at same period. AFAIK everyone said dtsi was the first engine made by Bajaj.



Well, I know about what catcon is and the the kat kat noise it makes after shutting the engine.
Like I said previously, exactly like DTSi, the benefits of triple spark plug can only accounted at high speeds or when the engine is under load. It all depends on the position of the throttle. If you haven't find this already then strip dtsi, triple spark plug bikes again till you find it. To put in simple words the ignition map/timing changes with the position of the throttle.
Like DTSi, triple spark tech isn't beneficial at standstill idling so you are never going to notice any difference on CO emissions. When manufacturer design any new vehicle, they and RTO/ARAI test emissions at all of the power range/engine load and not at just stand still. Unfortunately we can't do similar testing with the tools we have in backyard.

On my DTSi I do notice the change in the ignition timing every time. Even bike sound note also changes very slightly accordingly.

If the ignition timing doesn't change at all and you find it dubious then why would Bajaj use digital controller for timing?
If 3 spark plugs aren't needed then why don't people run their P200NS on single spark plug all the time? Why they bother spending money on replacing two of the spark plugs?



I know whom are you talking about.
And I'm not one of the those three. They annoy me too.



I'd love to meet you in real life and talk even a lot more than this. I have been following you almost since you joined the forum. I admire your knowledge and respect your skill set (which I know for sure not just limited to mechanics.)
When knowledge arguments burst wide open, most of the folks(dumb at tech) say 'fcuk off' and run away. I, on the other hand like to get my hands dirty. And when I'm wrong, I've been wrong multiple times and a few times [MENTION=19778]Bibhu[/MENTION] has corrected me, I don't feel ashamed that I was wrong. No ego here.



Second spark plug runs every time after ~4k RPM.



It is supposed to be low tech/ low cost from the start. I hope you didn't expect NASA to incorporate triple spark plug tech in their cryogenic engines.
You're not understanding Bajaj's approach. Bajaj wanted the tech for even more controlled combustion without asking more money from customer(use of Fi)
Triple spark plug isn't a perfect replacement fo Fi but it goes a long way.

Like I said, if you guys find a bike having better specs than this then I'll rest my case.

With a proper digital ignition even the mighty rd350 manages an fe of 25kmpl(ridden sanely ofcourse), where as with a normal cdi, the fe is 15 and on points it is close to 10.

@Cleaner: why don't you like to like posts? you don't see that link or your mouse can't reach there?
BTW have you got your website back online?

If it had digital ignition at that time then it is indeed super cool. Technology was mad in its days and now, we have to deal with sane products only. If you bring rd350 then it breaks the figures for duke 390 too who is supposed to have modern day FI leave alone poor bike like 200ns.

I did catch your point at first instance but I'm not ready to call 3 spark plug crude till I see better model without that tech in 4 stokes only(which I had asked at first time already)

I'm neutral to everything, I neither like nor hate anything. The fact that I do not like anything does not mean that I hate them, it is just that I'm not much interested in this "like" thing. Blame it on Facebook for making me a like button hater. Well, The mouse was actually consumed by a cat (Honestly, the damn cat chewed on the cable), so I'm back to touch pad now

Working on getting it back up, but I don't have the money to pay for hosting right now and from my previous experience I can tell that free hosting is not worth anything.





There was not digital ignition at the time of RD350, it had a points ignition system, later people like Ron Cinnoy made digital ignition system for RD350 due to its popularity among vintage riders. Even with a digital CDI RD350 will not be able to beat Duke 390 without stage 3 porting and expansion chamber as the engine design is old and there is a limit on how much one can milk out of RD350. I think after like 45 Bhp one would need EBC clutch plates and little more than that, gears will jam, to shift gears, one will have to take the motor completely out of powerband which is not feasible. The RD around 40 Bhp would be good for street riding and occasional crack on the throttle. Beware, RD 350 has almost no engine braking as it is a 2-stroke motor and the brakes are just a little bit more effective than that of Raleigh Roadster bicycle.

You should try riding your P180 with one plug disconnected and see the performance and efficiency for yourself I think.

+1 tried to ride my bike with one spark plug removed.
The bike gave misfires while accelerating.
My mechanic told me that below 4k rpm 1 plug is responsible and beyond 4k rpm, the load transfers to the other spark plug.

So far I could not find any reference to the second plug firing only after 4K RPM remark.

This information might be for initial oil pulsars.
On current pulsar second spark runs after ~4k RPM and engine is cut off after 10.5k RPM.

Just wanted to put across the info regarding that 'both plugs are not always on active duty' - there will of course be variation between various UG's ..
Are you sure the second plug fires only after 4k rpm on the current pulsars ? I doubt so, and think it would be much earlier. I'd be happy to read this info from a reliable source like a manual or something ?!

Like I said before it's from current manual itself.
