I own a TVS Apache RTR 160 (a single cylinder, air-cooled, carburetor motorcycle.) with close to 35000 kilometers.
The bikes loses power in 2nd and higher gears, between 5-6.5k RPM. It loses power no matter how much I open the throttle. It is normal up to 5k RPM and above 6.5k RPM.
There has been no considerable increase in fuel consumption. The gear does slip at times, but not all the time.
I tried changing the spark plug, but to no avail.
Is it a failing clutch plate or a pulsar coil? Could it be something else?
