Burning of oil will not be solved by upjetting.

Take your bike to the service station, and check if they have a compression testing gauge.

Get the compression of the cylinder checked. If its below normal, then you will have to get the head checked for proper seating of valves, and also of no play in the valve guides etc.

Otherwise you will have to check the piston rings for wear/tear.

Hey abhishek,

Upjetting has nothing to do with burning of engine oil. The oil would continue to burn irrespective of whether you upjet or not. Although, you should ensure that your engine is not running lean, for which upjetting is a must.

Also, although I am not aware of the technicals of the Pulsar engine, how did the mechanic show you deposits on the valves? Did he open the head, or what?

The mechanic had opened the valves and showed carbon deposits on it.

Thanks. The reason I had asked that question was because this was a service for which you had given in the bike.

hey guys his bike is now running on lean mixture, so his engine is running hotter than normal.....so it may be consuming more oil than usual.

Hey, so whats the solution for this. Is upjetting required?

abhishekjv I was running K&N a/f on my 150 with bigger jet size of 117.5 but it was useless I got problem like
1>Piston ring gone
2>Piston gone
3>Valve gone
4>had to change clutch plates and pressure plates
5>Same problem only 100ml of engine oil from the engine (Castrol power one racing)

so take my opinion are remove that K&N a/f from your bike its a piece of junk it will destroy your engine.My K&N is laying useless
K&N are not ment for Indian bikes they are manly made for cars and SBK.Nothing as good as stock bike remove it and forget the idea of re-jetting.I was getting 30-35kmpl after re-jetting its useless take my words or fasten your seat belt for spending thousand on engine work....
In my knowledge your Piston ring is gone so replace the rings,but replacing ring won't help much try to put new high quality piston.....
rings and piston will join perfectly both will cost you 1100Rs from then onwards always use Mineral oil.I am using Motul Mineral oil and the level is not decreased a bit from 3000kms

Hey abhishk, Running just with K&N or upjets will screw up things for sure.as they are not meant otherwise the company would have already done it.

Now when you are already running on it,as far as your question is concerned,if the engine is picking up oil,get the lower ring of the piston changed.

Reagrding the upjetting, you will first need to upjet it, then put better spark plugs to give better ignition and then to get the ignition timing advanced and not just that the spark cords also changed to give them proper current.
moving to bigger carb will lead to get the bike OVER with petrol again and again.
until done by al means of adjustment by a proper trained mech!
