Black smoke from bajaj pulsar 150cc ug3
Dear Sir, I am having bajaj pulsar 150cc ug3 2007 model. I serviced my bike before 15 days and changed bore, piston and also serviced the head valves and rings. Last week I ride my bike in highways after that day I saw black smoke from silencer when I raise the throttle at 4500rpm. I saw a mild black carbon in silencer when I touched the silencer hole. But at that time engine oil was normal but day by day engine oil is going down. I checked with my mechanic but he is saying not a big problem. I am afraid will it be Piston and bore problem again. Already I spend 7k for servicing. Please suggest me whether its piston and bore problem or head and valve or any other. Thank you.
