Ask your mech to check for valve oil seal, condition of piston rings,clutch plates and clearance . If he his well educated on ZMA he will come to know what is the root cause of the problem.

Just check your Exhaust, while touching there, if you could feel the oil then its sure your Bore/Rings have got worn.

If you can't see the oil dripping then this is the cause.

Hi, thanks for ur suggestion, after riding bike for 20kms i put bike in neutral and accelerated hard honding a white paper at end of exhaust and couldnt find any oil coming, tried with a finger inside exhaust also, it was all carbon no oil i suspect gear leaver oil seal as its oily(but never drips on floor!) but then again it may be chain oil also..

As there is no any symptoms for your oil disappearing now I am also confused, the only way is it should drip or it should be burnt.

Now I have a doubt can any one clear this.

Will synthetic oil leave its greasy residue in the exhaust? or will burn in to dry carbon?

This is a very crude method for checking it. Get a compression test done from the service centre.

Will get a compression test done ASAP

i face the exact same prob with my uni when it did similar odo with motul fully syn 300v 15w50.. the culprit was the oil.. don't know why,but by the end of just 1700 kms,there was abt 500ml left.. but then the piston rings were also worn out.. so i simply opened the head,put new valves and piston rings,decabonised the head and put the valves and got the valve mappin done,checked the piston and bore - every thing was fine , so left it intact,may require a cam chain and tentioner - in my case only tentioner,as the mech damaged it... did a run-in for 1000 kms and till 60k kms - i.e is till i sold it,it was as good as new,infact even better.. much punchier acceleration and sound note.. this might also be due to the oil which was petronas sprinta fully syn 10w40.. from 40k to 60 same brand oil,change every 2k kms... never needed a top up.. i also used the bike with k&n for abt 8k kms but with upjetting..so reverted to stock after head thing and was wonderfull...

Thanks dogg!! when i changed the oil lately, less than 100 ml was left! the mech told me if ridden for around 100 km more, engine would have seized!! do u think i may have damaged the piston or bore or any other parts?? will get the piston ring and valves checked tomorrow. any other thing i should get checked? never looked into an engine before, hence not much idea abt it.

wow 100 ml?!? i suggest u to get a thorough check of clutch plates as well as piston rings.

faced same prob on my P-150
remove your k&n ASAP..!! its killing your bike oil level are decreasing due to piston ring your piston ring are gone for sure,if you get it change then after sometime your engine compression will be lost so its better you change both piston and ring..

+1 100 ml??? s%^t bro.. check the clutch plates also and relace if necassary..this was in an other topic but is almost the same, so here goes


u need not open the engine.. all u need to do is -

1.remove the tank
2.remove the carb
3.open ony the head

i.e first open the head cover - this is where u find the taplets,then open the head - this is where u find the valves.. after u have opened this,u'll be able to see the piston... befor this , loose the cam chain tentioner and remove the cam chain form the gear and secure it with some wire..
then remove the cylinder block .. u can then see the piston along with the connecting rod.. just remove the piston from the connecting rod and thoroughly inspect both the piston and the cylinder block walls.. there should not be deep (< 1~2mm ) lines or scratches on either of them..
small scratches which look just like fine lines are ok.. retain all bolts and washers..

since urs is a pulsar and i did all this on a uni myself and on a pulsar 150 by a mech,here goes.. some points may be missin...

now start from the top side of the head,check the rocker arms,the cam gear and the cam chain and replace if necessary.. then goin to the bottom part,after removing everyting,there will be lot of carbon on the head,get it cleaned which they do with some machine in an engg shop.. also at this point,get new valves which have to be put in and they are also put and and " mapped " - which is also done in the same kind of shop.. then replace the pison rings (tell them standard size) and all other required parts along with new oil(castrol active 20w40),put is all together and do a run-in for ~500 kms...also get new plugs - i recommend the ngk platinum g-power for ur bike which r 130/- each.. u can find the part numbers in ngk india website under part search-2 wheelers..
also change all the seals and get the pasted properly with a particular seleant which the mech will know.. they may put grease to seal some stuff,but see that it does not go on the inside..
but if there r deep lines and if the mech says that re-boring is compusary,them get it re-bored.. they may insist on doin reboring even if not necessary to get some money,but ask him why and listen to wat the mech ahs got to say,if it seems like a bluff,the tell him no.. but if it is genuine and if he's able to show u proof like lines,etc then go ahead..

enjoy

i have uploaded the picks of my uni and few of the pulsar engine internals.. hope this will help..
Picasa Web Albums - rohit - bike stuff

and abt the mech -
1. see the shop - it should be big with all the necessary tools and atleast 3ppl..
2.talk to the mech's and see wat they have to say.. u act like u know nothing and listen to what they got to say,if ur convinced and if they look genuine,then go about it.. gat all the spares form bajaj.. will be a day's work and cost approx 1000 including labour till rings replace

good luck

Dude no chance on earth can a k&n kill a bike !? ! its named best air filter in the world and has won many awards too . :/

awards for RC-1100 no for cars performance a/f not for indian bikes which uses Lawn mower a/f..

in a way u r right,it cannot kill it completely but can throw it into comma.. the reason - improper jettin and fuel-air ratio.. if there is to much air and less petrol,then all the internals get more heated than they normally do,which on the long run will @#$%up the engine.. all those awards are for those american/european cars.. if u go to those countries and say the "fastest indian" has 21bhp - they will roll down and laugh their a$$e$ out and some may even die laughing
