Problem with oil leakign from 98 cr250

[CR_dan]

Hi all, new to this forum
I have a 1998 CR250.
Its leaking oil at the lower engine mount where the case halves meet.
Theres no cracks on the case anywhere and it only leaks when the bike is being ridden. (when the biek is staionary and idling it wont leak)
Anyone know what it coudl be? Coudl it be just a case halve gasket? I have split cases before so its not a problem.
Im new to this bike so was wondering if anyone else has a similar problem.

Thanks
Dan

Welcome to ATM.
I've never maintained a 2 stroke and I don't have that many years experience but I can't imagine the leak being something other than a gasket. It's possible the previous owner re-used the gasket or put some bond on it where it was torn or something. I'm sure you've checked the bolts to make sure they're snug.
