There are unfortunately no good tricks for fixing a leaking crank seal, short of replacing it. First, where is oil getting in? Are you burning transmission oil? Does your transmission oil smell like gasoline? Is there oil behind the stator cover? Just trying to clear that up before we go much further. As for tips, you are in luck. The illustrious rbates9 has provided us with a sticky, dedicated completely to this very subject. :partyman:

haha yeah didn't think so and I haven't checked the oil well I checked it but didn't smell it but I changed the oil like right after I herd it it run then I rode it around for 5 min and was smoking bad but there was antifreeze down in the bottom of the crank from when I took it apart (didn't think to drain it) so I put a little oil in there while it sat because it took weeks for the parts to come in so I didn't want it to rust up but that's what I tought it was at first(why it was smoking so bad) but then after running it for 30 min doing heat cycles it didn't clear up but I looked in the oil glass and there was nothing but if I leaned the bike all the way over I would see the oil and the oil was still a nice gold brown not like gas was in it and I put a whole quart of oil in it when I did the oil change... so I have no idea haha :rolleyes:

Hard to judge by smoke. Are you for sure losing transmission oil, and it's not leaking out onto the ground?

You may want to clean out the pipe and spark arretor/silencer to eliminate those two variables. (old built up oil/carbon inside them)

Fill the oil to the proper level, with the bike level, then ride/run it for a while and after allowing it to drain back into place, measure again. If it is lower, then the engine has a leaking right crankcase seal.

If you get bored, read up on vacuum and pressure testing. A vacuum test would be used in this case.

if it wasnt good enough to stay in whatever engine you drained this out off...why in the world would it be good enough to go into the KDX?

Exactly! Do you really want to subject your transmission bearings/bushings and your clutch discs to used, contaminated oil? Not me! I would rather burn through the good stuff or, better yet, fix the problem!

Clearance in there is pretty slim. There's no room for chunks of metal anyway. I may have an e series head out in the shed, I will check. For the record, grammar and punctuation go a long way. That was pretty painful to read.

Your phone may add and delete things but you still have the power of prof reading before sending. And what the $#@& is with everyone talking about their problems and having to start and end with that stupid "haha" bull ****? Most of us, or at least I don't care if your giggling or touching your self or what ever the hell your doing. This is a web site. Not a text message. There is the little faces to the right if you feel the need to express emotion.

But you do not want to use a hone on your cylinder because unless it has been sleeved it has a plated bore and honing will destroy it.

If money is tight and you can not afford a new piston but can find a very good used piston then give it a try. Don't expect a long happy life out of it. It may go a long time but it may not.

If there was metal floating about in there scoring things up, the piston is almost certainly hosed.
