Hi Vargis Bhai and all fellow members. I just need suggestions and advice on couple of Points. I have 2011 Model Hero Honda Karizma , which is clocked around 45000 Kms. Now the problem is :- 1. up to 60 KMPH its going smooth no Issue but not going over 60 until 5000 Rpm. ( and all in sudden it jumps to actual speed and pick up ) I have been facing this problem for the last 3 months. I have changed the clutch Plates , Corroborator settings , but problem is still same. Over Heating , Vibrations , smell of burning fuel and loss of power up to 5000 rpm also there. Mechanic checked again and suggested for engine work but there is no black smoke , no loss of engine oil. milage is still good Kindly suggest what do i do . Moreover i want to take this bike to leh this year. Is it good take bike there after engine work.
