This is a very common issue with BS4 version Bajaj Pulsar 200 NS bikes. The bike wont cross 95 km/hr in 6th gear, struggles to get to redline in gears 3-5 and the tachometer gets stuck around 6000 RPM. Checked the carburettor, changed clutch plates, wheels are also free, changed air filter and regularly changed the engine oil. Issue has been around since 18,000 kms on the odo. Now I am at 31,000 kms, still unable to find what is the cause. Any idea?
