KX 125 leaking oil

[dante]

Recently I noticed that my bike had almost no oil in it... I put more oil in and it leaks out as the bike runs... It does'nt foul plugs, but seems like the smoke could be whiter than usual but it is a two stroke and it's hard to tell... It always smokes allot right when I start it but i remember thinking that there was allot of smoke when i first started it yesterday... It looks like it is leaking from the right side around were the swing arm attaches to the engine... It's all clean around there and fresh oil is coming from that area and dripping down all over the suspension link, and cakeing the rear fender and wheel... I searched the archives and I guess it's a crank seal, or water pump seal, but I thought I'd post to get some fresh input... The oil isn't milkey in any way...

thanks for any help

If he's talking about the right side of the bike as he is sitting on it, the leak would be nearer the brake pedal. I think he said "right side" - the countershaft is on the left of a kx125.
