    Hello everyone. Been having a problem with my kfx 400 that I can never get a reading on the dip stick. The bike takes 2000ml of oil so I added a little extra to try to get it on the stick and still nothing. If I drain it I get out the exact amount I put in basically so it’s not burning it off...

    I just replaced the timing chain in my kfx and now when it turns over it's blowing air back out the carburetor, which is the exact same thing it was doing with the old chain in. Could someone please help.

    Well here it goes. I used to ride the heck out of my bike until the police really cracked down on our riding spot. So my bike has sat for about 2 years.
