Hey guys, need some advice from all of you.
My p220 is 9 months old and total run is 12400 km.
Over last two months, the performance of the bike is significantly dropped and I am worried a lot.
First of all the pick up is not as good as it was.
The fuel efficiency drops significantly.
I had to hit hard now to reach around 120-130.

Although I regularly service my bike from the showroom guys on time.
My mechanics says sprocket needs to be changed and the engine is opened(engine khul gaya hai gaadi ka), what that mean.
while bajaj servicemen says, it happens when bikes goes for long tours.

Help me guys, I really want to know that how i can improve my bike performance to normal without damaging the engine.
