I have been using Bajaj Pulsar 150 UG3 -2008 Model.It has crossed 65000KM in Odo reading.I usually change the oil at the interval of 2500Km with Gulf 20W50 oil.I for got to change the oil last month ,It has crossed 3000Km ,It started to stop in between .I just checked the oil there was no oil at all.So after this problem I get black smoke with little oil in it.I cleaned air filter and tuned the carburretor.After that smoke was reduced and no oil in smoke.I took it to bajaj ASC.They opened the engine and said that the engine cylinder wall got scoring and it need to be replaced with new cyl head and piston and valves,clutch bell,timing chain .They charge Rs11000 for this.Should I replace it all or only cyl and piston .Please suggest me .I asked local mechanic he said it costs only Rs3000 but Bajaj ASC charging Rs11000.
Please suggest me?
For your info:
After smoke also the bike was smooth and no noise.It gave a mileage of 35 to 40 .
