2009 KTM 450 Exc oil issue

Recommended Posts

So I just did a long multi day ride in sand and ran it pretty hard and got home and went to change out my oil and low and behold I opened the oil drain and a trickle came out. Defiantly not the 0.65 liter I put in. 

 

So im thinking maybe pistion and rings? I am going to get a leak tester. Firstly, test it in TDC with the TDC screw in? If it is greater than 10% I’ll do piston and rings. Secondly, Should I be worried about the oil pump gears with low oil volume? 

 

Im hoping I haven’t ruined my bike. 

 

Thanks for reading

How much oil is in the transmission side?

It was pretty common for the early XC4 engines to lose a seal and blow all the engine oil into the transmission.

I didn’t measure the oil coming out of the trans side but it was a good amount. If it is the seal would that be a full engine tear down?

I had a 2009 400 XCFW which had high oil consumption. The rings wore quickly using the OEM parts. I put in a Wossner piston kit and the oil consumption was solved. I know of two other bikes of the same vintage that also had the problem. They both installed the Wossner kit and had great results.
