[Dupontster]

My 400ex started ticking. I dont Know why thow. Me and my dad just checked the valves, but it still ticks. If anyone has had this problem or Knows what is wrong please give me ways to fix this.

We just checked the oil in it and it was bone dry.We been checking the oil and we just got the 400 so were pretty new to it but is the oil supposed to stay in th oil tank or does all of it go right in the motor.....Please help us out.

did u check the oil with the motor hot????


there should be oil in the tank... if not u got a major problem...


mine also ticks... its done it for a year... they told me it was the cam chain tensioner...

Yes we did check the oil when it was hot. When we checked it it was no oil on the dipstick. What could be wrong with it.

could be low octane gas:confused:

just keep the oil around the full mark on the dipstick. you can try changing brands of oil and you may not use as much. 400ex's have a tendency to use a little bit of oil when ran hard. i went to mobil 1 and haven't had a problem since.

The 400 gets hot and, to me, regular motor oil just doesn't cut it. I also use Mobil1 with the red cap. Make sure you are checking th oil correctly. Idle for 5 mins and then check it without screwing in the stick. If its low, add oil until full. Heck, you may as well change the oil. It will hold 2 qts.... with a filter change and you may or may not have to crank it to get the last bit in.

Just FYI, when I used regular oil, it ticked whenever it got hot... and it still does if it gets REALLY hot. Otherwise, when I first start it, it may tick for a second and then its the typical 400 purr...

when you check oil, let the engine idle for about 5 mins without touching the throttle, blipping the throttle will make you get a low reading. So will riding wheelies.

On my 440ex the piston pin hole is ovaled out. The extra clearance was causing the motor to make a tapping sound. After some time, the tap noise started to turn to a knocking noise. After investigation I found out that I need a rod/crank combo.:eek:

Ouch! Glad you caught it before it grenaded itself!

Man that sucks. We talked to my friend and he said it is my timing chain and tensioners. So we are going to try that.
