Re: Pulsar 220 DTS-Fi
well...the chamber connected below is a connected by a l-shaped pipe.....basically the box/chamber is a resonator unit which is electronically tuned before fitting it on the silencer/exhaust pipe/assy....since its a rectangular box and flat...the exhaust produces a lean sound compared to free flow exhausts...while the engine is running and u put ya hear chose to the unit(without burnin ya face) ul hear mild sounds.....similar to what u hear when u put a shell to ya ear.....that's the swirling ...since its a resonator...it has to make sounds...this in turn changes the entire function n flow of the emission...so since the gas is trapped in the chamber and manipulated vis-a-via swirl characteristics...it provides a pull torque....by which the engine does not need to provide that certain torque to move...therefore great movement at low speeds on high gears....its not exactly a pre-exhaust chamber....but its a resonator...a tuning unit(not electronic.....but analog{obviously!!}).....................

By the way...was riding to the main city....a 20 mins ride...when the bike suddenly stopped and wouldn't start again....the ignition would crank up but wouldn't start the bike....then realized that the fuel pump wasn't working...so I checked the spark plugs.....tried shorting off the starter relay...still no progress...this was at 9:00 am...(and at that time...in goa...there aint a single shop open) ...waited till 9:40...walked the bike to the village market.......spoke to local mechs....well..they readily denied to try their skills on a 220...(I was both happy{THESE ANADI'S AND TOUCH MY BIKE??} at the same time exhausted and dismayed....plus pushin the bike took its toll on me....) then called my friends to pull the bike to the Bajaj workshop(more of garage) close to where I live....was a 15 min ride...friends come by 11:30 am.....and they tried "dhakka" starting the bike....but whell....still no progress....then reached the Bajaj mech....he tried all he could....realized the starter relay was not supplyin current.....had to be changed....but didn't have the part...went to a friend's garage....local one..they had the avenger relay...which is a single socket...and apparently the same fit for p220 too.........ignition was a bit better....but still no progress with the bike...I kept tellin the mech to check the pump and the injector...but well..........."nahi saab....aapko kya pata hain?? who problem nahin hai...." then I called the senior Bajaj engineer from the north region of goa....and he told me that...there are 11 sensors for a 220 fi.....so even if a single sensor has gone kaput due to water or anything(note...I had washed my bike the prev day) the ecu senses a engine failure...n to protect the engine from further damages....shuts down the startup thru other methods.....then the mech gave up sayin tellin me to take it to the workshop or the bigger outlet of theirs.....then by the time it was 4 :30 pm...we had to take the bike back to the city...so another half an hour ride thru "dhakka" movement...(can u believe...a cd dawn could pust athe p220 to 60 speeds?? wow :P ) ....on reachin the centre.....got a job card done...n now the bike lies there like a cancer patient for its mri scan n further diagnosis.......................
...ps....the display console kept displaying " ecu 3.9" any idea bout this??

Can you please explain, what's swirling sounds of exhaust tec and the effects of it.
