my 400ex has some problems with the oil when i went riding it was running fine but then a day later i just put oil in it that day i went riding for about 20 minutes or so and then the oil is all gone and there are no leaks cause I then put some more oil let it run for about 10 minutes it was nearly gone and i saw no leaks any where. Any suggestions?

 

Is it smoking??? You aren't burning tons of oil out the exhaust are you???? Do you end up with a bunch of oil in the airbox????

 

theres not so much smoke a lil right when i get it going then it goes away in a minute and no i didnt see any build up i thought it might of been running real rich

 

Has to be going somewhere, I would take it to a good Honda dealer and request a leak down test down, anything over say 15% your motor is bad. This test will tell you where your motor is having a problem also, leaking valves, rings.

Are you using Honda oil or what kind, I've hade experince in some oil's causing oil buring and Honda won't unless your motor is worn out.

 

i might try using a different oil i forgot which i was using since last time ive tested it was about 3-4 months ago.

 

I know of several people who have experienced massive oil consumption with the 450 engine using Honda oils, and a switch to Maxima Extra cured their problem. But, the 400EX has a long history, and no such problem has come up with them.

 

what exact oil i need ?

 

and also thanks for all the responses [img]i/expressions/face-icon-small-smile.gif[/img] thanks a lot

 

The 400ex and the 450r motor are totaly different, Honda has said themselves that the 450r motor when you run it hard WILL USE OIL.
