check for the petrol mixture screw on the carb... check if its tuned for lean mixture or rich... i feel its set for rich mixture... i believe rich mixture gives u more power....

Well as far as V1 is considered

You cannot do much on the Mileage almost every V1 gives only lessthan 35KMPL

I do had a THird hand V1 for 3months - i tried almost every aspect to get a good mileage - nothing worked it stayed to give only 30
I even tried to make it under 60 alltime - but it doesnt matter
Even you rip her hard ride her softly she will return only Poor mileage

Facts for Lesser Mileage:
1 - Heavier Body
2 - Superb engine
3 - Older efficiency systems

DTSI modela can give better mileage - this was the fact that Pulsars were Given DTSI Technology

Nothing else can be done for its mileage improvement
Even bajaj said V1 can give only that much mileage

@Sunny- thanks for approving

@pk28.karthik - tuened it according to feel....its been made a few turns on the rich side ..will try making it a bit leaner n see

@Thunder - mine is the dtsi one with exaustech and 18 inch rims...not the classic ..yes its got a better engine than the newer one's acc to me too. but the milage is still too low.i mean i 180 too gives similar if not better figures

any other possibility's of low economy??

ECU tuning? and everything else fails ,try a new std cylinder bore+piston kit ?.I dont know whether it is easily available.

Hey Karthik!

Bud, please don't feel that I am contradicting you, but then a richer mixture would give you a cooler engine, & if you make it too rich, a carbonized engine, which will soon start heating up a lot due to carbon deposits & if things get much worse, pre-ignition due to these very carbon deposits.

To increase engine power, one has to increase the fuel amount & also the oxygen content, so that the fuel can be burnt efficiently to release maximum power. That's why nitrogen oxide is called rocket fuel, because apart from having the fuel (in the form of nitrogen gas), it gets additional oxygen when it breaks up into constituent molecules.

Richard, I don't have any idea about Pulsars specifically but then I feel that the possible causes for a low mileage if the carburettor settings are good, could be a simple leak, & if things aren't as good, then it could as well be your bike needing an oversize, which I don't know if it's available for Pulsars. Get your bike checked, after you have made sure that it's not a leak & that the carburettor setting is good (i.e. not too rich).

Take care.

Happy thumping,
Prakhar

Need Help

My p200 always suffers tappid problem every now and then i have to go for the tappid adjustment.. so can u all suggest a permanent solution for the above mentioned problem

my bike have completed 12000 km

Dude that is what i was telling... richard has mileage issues and since the mixture is richer petrol consumption will be more.... getting my point.... i aint no expert but still applying some mechanics in here....

@ richard
let me know the result after tuning back the carb....and also check for the petrol tap for any leakages or breakages..also check pipe which brings air to the carb.... sometimes the petrol flows back into the air pipe leading to petrol wastage(hence consuming more petrol\)...

@prakash_mvpa - what is ecu tuning where can it be done and how much will it cost

@blackfire_9 - agreed...i keep my air filter very clean so there is always good breating..so the bit rich mix..

@pk28.karthik - have got the carb tuned back to default by the mech...but the bike is now feeling a bit ruff and strained(Clear proformance drop noticed)...there is an increase in mileage though but its still quite low, it gave me around 37 this time...and yes there is a leak but not on the air pipe..but on the pipe that connects the carb to the head...i think its made of plastic??

try cleaning the carb... i feel the combustion mixture is not balanced... i mean the air and petrol (correct me if i am wrong)...
regarding performance drop, yes when lean burn power generated will be less... dont worry about that...
but tell me in which way is it getting strained? u mean the gearing? check the pin adjustment in the carb as well...

what i feel is basically the mileage issue is only in carbs.. so check the carb thoroughly... and ya clutch arrangement

To be in correct Frankly

Pulsars are kind of Bike which gives problems after two or three years of running - (every one knows)

Take it in an lighter side - i was also an X owner of P150 and P200
So i knows better about them
You guys wont know howmuch i suffered to increase my P150's Mileage
The producers of Pulsars - Bajaj itself accepted that older pulsars will give less mileage - and nothing can be done for it - and forced me bye UG3

For my bike i change the following things with the bajajitself
1 - Both the Sprockets with Chain set
2 - CLuth plate and even Gear plate
3 - Carburretor tunning for LowMixture
4 - Cleaned the Pipe
5 - stock tyres - changed to alloy wheels

Almost everything as a stock bike will have
But after doing these things also it gave only 30 - 32KMPL
So there is only way

1-Go for Reboring - but not with bajaj - some other trusted Mechanic
2 - but reboring can be done as for your choice
3 - GIve away performance for mileage
4 - Give away mileage for Peroformane

By making the lean mixture to run - you will face many issues
1 - Engine idling
2 - Cold Start
3 - Lower Pickup
4 - Strained Engine sound
5 - engine lacks breath in higher revs..........

So the best idea to suggest is stay still - and have your Bike as it is
If not sell her for a new Bike

check for smoke from Exhaust which indicate worn out Piston rings.

@Thunder : reboring on a fully aluminium engine?I think may be some sleeve work?

@richard :ECU re-tuning is the extreme step and I would like to say -skip off that idea ,I inquired and the reply was negative from all corners.no body seems to have any idea about re-mapping(tuning) ECU if at all.simply not possible even with bajaj pbk SVC ppl .

but you can call bajaj factory to supply a spare barrel+piston kit ?if at all your engine is too worn out in all aspects.

A simple solution: If your bike's a bit noisier too, just see if the rubber tubing that connects airbox to carb is cracked or not, or the one thereafter.

I've gotten 20 mileage on my caliber due to similar simple reasons.

please check simple causes first
