Dude, I had a 200 cc bore on my Pulsar 150V1 with porting and polishing. On top of that I was running 210 psi compression, close to 12.xx:1. Used to ride down non-stop at 120 during trips and tours. Always used 20W50 semi - synth or synth oils. Only Speed or Speed 97 would work. Any other fuel and it would start pinging. Never faced any problems with over-heating etc. Only improvement : truckloads of low-end with marginal improvement in top-end even with a 40T rear sprocket. But the clutch would give up in around 15K kms.

Errr....can we hear something new

BTW, are u running a freeflow filter?

There is something called as plug rating, which will determine what plug will work for you. A plug can make ur engine run hotter, normal or cooler. If your engine is boiling there is a reason to it. Its running too damn lean. Its not cos of DTSI or VTEC in the pulsar engine.

**Joel** · 11-05-2008, 05:45 PM

^^who is stopping u from upjetting the engine if its over heating. yes the stock bike is lean. And thats the only reason why its over heating.
Aparajith's bike was running a really huge mainjet and the mixture was never lean. No wonder the overheating was far lesser. But would need strict high octane gas to stop pinging.
But the point is, is it really worth it? It indeed had loads of torque, but where is that much needed outright performance?
Thats where bikes like the RTR and even R15 for that matter takes the cake. Everytime u work on the engine, it SHOULD lead to a propotional improvement in power and performance. With 50cc more, if the gain is only 2-3bhp, is it worth the effort? Frankly the P200 does not produce anything more than 15 odd bhp. 18hp is crap. Who is willing for a dyno test, we can prove this. And a p220 does nothing more than some 17-18bhp at the crank.

@Apar - never, even if I get one for free.

**Aparajith** · 11-05-2008, 05:48 PM

^^Yep. To make points clear I was running a 120 main jet.
Joel : Really waiting and expecting for that stock RTR vs stock P180, P200 speed test photos and videos man. That will clear up LOTS of doubts here.

Wow..never thought the post would grow so quickly..!! anyways lets see what happens when the bike comes out...Im prepared for whateva is gonna happen..i wanted to try it out on my bike n ive done so now...n im sure Mr Rajkumar knows what he is doing..!!

...n yeah il keep an eye out for the heat issue...but since Aparajiths bike was running a 120Main and didnt face that prob im sure i should be fine as i was already running a 125Jet with just the exhaust and the filter...as for the clutch..it was already modded by Vivek aka tectrac but lets see how it all goes once I get the bike tom...n give me about a week to run it in..!!

And to all the guys who had asked me about the performance gains and stuff...The bike is not in my hands yet..i just opened to thread to give you guys a heads up..will post all the figs as soon as I get them...cheers

Think u missed someone on that list, Aparajith?

**Samarth 619** · 11-05-2008, 06:54 PM

@ Joel: But dude, doesn't Dyno reveal figures @ rear wheel, then how do you think you got that 17-18 bhp @ crank for P220 ...

You aren't saying the company cheated us .. are you?

Agreed that all companies exhibit output at crank. But there is a typical transmission loss of 2 - 2.5% IIRC which means the rear wheel output is normally that %age less than at the crank.

Once Joel tested the P180(no idea which version) on the dyno, it was putting out something around 12.xx bhp at the rear wheel. U do the math!

That percentage somehow happens to be huge number for the entire Pulsar series! Especially compared to the other bikes.

**EL LOCO DIABLO** · 11-05-2008, 07:26 PM

Can it be because of the 120 sections on the rear??

**Aparajith** · 11-05-2008, 07:47 PM

@El loco : No yaar! The difference between the output at crank and wheel is no-where connected to the tire width. It is the difference between output of bhp at the crank to the effective power transferred thru' the transmission. The wheel is not part of the transmission.

Agreed at rear wheel it will be less due to losses but at the crank was there any difference, what was the calculated bhp ???

**Aparajith** · 11-05-2008, 07:56 PM

I do not think we have the right equipments to measure output at crank. So essentially we can conclude that either the crank output is less than what is claimed by BAJAJ or there is a HUGE transmission loss in the Pulsar compared to other bikes of similar config.

**rossiter** · 11-05-2008, 09:55 PM

@Apar: What you say is true.. but the normal (read: optimistic) losses are close to around 10-12%, according to what I studied a long time ago

That's the reason the R15 actually is a very well engineered bike, the transmission losses are very low relatively, and from what I hear the newer Gladiators are also very efficient in the transmission.

@prashant benz: Keep us updated with your before and after feedback(s).

As for me, my V1 is happily stock, with a tyre change done half an hour ago. After 37k, have shifted to M45s at the back, and M62 in the front

**Aparajith** · 11-05-2008, 10:29 PM

^^Never knew that. Thanks for the info. Either ways, with or without transmission losses I miss my modded V1 for all the hooliganism I did with it!!!!
