Why is my 300 smoking?

Today when i was riding my 300ex started to smoke out of the exhaust, it's kind of a blueish color. It only smokes when i let the gas out. Does anyone know what is causing this?

You could need a set of rings or your using to lightweight of an oil. What kind of oil do u use?

It was 10w-30 it was kind of clear to. Do you think if I just changed it and put a new oil filter on and clean the air filter it would quit or not.

Yeh i'd switch to a thicker oil as well. Mobil 1 15w-50 oil is what i use and it stopped mine from smoking. Dirty air filter could be the reason as well.

umm--- have either of you lookedunder your gas tank after it's been running awhile- there's a rubber tube- i've noticed this to emit smoke as well- is this normal-

If you want your quad to stop smoking you should give it some niccerette.

No I have a 400. When mine was ran hard it would smoke a little after letting of the gas. It was because of the honda oil i used. It breaks down way to quick and then makes the quad smoke. I switched to mobil 1 15w-50 synthetic due to good comments about it on this site and it doesn't smoke anymore.

Yeh 10-30 is a pretty lightweight oil to be using in an air-cooled motor.

hey anti, did yoo add me to your icq list? msg me sometime. are you MJwannab?

No I did not add you to my icq list.

All i know is that is from too much gas in the carb. If you press the throttle in a couple of times when your quad is off and then try to turn it on, it won't most likely because it's flooded. There is too much gas in the carb.
