Question about Hero Honda Motorcycles
White exhaust from Karizma at higher revs in morning start up
White smoke= lean fuel, dark smoke= rich fuel. white smoke also could mean mean a blown head gasket allowing water to mix with the oil (very bad). Run it for a bit then take out and look at the oil filler pug. if the oil is frothy or bubbly and has the color of hot chocolate there is water in it. Replace head gasket and flush all systems immediately! Pary for the best

SOURCE: white smoke coming from exhaust
White smoke could indicate coolant in the combustion chamber. Not likely if you have an air-cooled bike. It could also mean that you are running in a cold climate, if the temp is around 20 or less I would call this normal.
If your bike is water cooled I would keep a close eye on your coolant level and oil level. A blown head gasket could allow water to get into the combustion chamber (causing the smoke) or mix with the oil (even worse). If you notice it using coolant I would have it checked out by a mechanic. If you want to check it yourself, do a compression check on both cylinders. If one is rather low, there is your problem.

Its most likely your rings. They get worn and start letting oil into the combustion chamber. They aren't extremely hard to replace.

fuel carburetor problem! it causes most of the spluttering problems i have encountered with mine so far!
it could have blockage and insufficient gas enters on it during high revs!

On a 2 stroke bike cause of smoke is due to excess oil in the fuel oil mixture, incomplete combustion in the cylinder or the engine oil finding it way in through the piston rings into the firing chamber. Check the oil levels and clean the plugs, which must be black in color by now, so replace if possible and if engine oil is low, the change the piston rings. Also look up the carburetor jets/nozzles are clean and the engine gets the correct fuel/air mixture by adjusting both fuel and air jets(turns)...sodeep
