Why do my air filter get water/oil clogged,white smoke when i rev engine and water shooting out by exhaust

SOURCE: 04' ninja blowing white smoke from exhaust.

if that motor is water cooled... you have blown a head gasket

SOURCE: white smoke blowing out the exhaust and oil consumtion on r.cyl.

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

remove the exhaust and the head cover with the valves, no need to remove piston yet.

check the seals and the piston ring for any damages and replace parts if needed. check your exhaust ports for any leaks and replace seals as well.

Sounds like an air leak between the carb and cylinder. This would lean the fuel/air mix causing a lack of power on hills. It can also cause the bike to rev up by it's self on idle and flat surfaces. If the bike is not over 3 years old you should be able to tighten the manifold clamps and then tighten the manifold mount bolts. The rubber should still be soft enough to re-seal the connections. If over three years old the rubber seals and manifold connections are probably hard and cracked and will no longer seal properly. Just get new seals, gasket, and rubber manifold and you should be back in shape. If not, it is possible the crank seals are the problem. They can go bad and lean the mix. I mention the seals last because it is not an easy fix. I hope this helps.

You could have a carbon problem .Try checking your silencer for blockage or it maybe the engine need a good decoke .
