I picked up a 1999 YZ250 last fall and only had a chance to ride it twice before putting it away for the winter. I noticed that both times I rode it, there was oil leaking from the exhaust. The first time was right at the engine exhaust/pipe connection which was corrected when I bought the missing rubber seals for the exhaust pipe. That just transferred the leak to the end of the silencer at the end of the second ride.
Everything I have read leads me to think that I need new oil seals in the crankcase. Does that seem right to those of you that know what you are talking about (unlike myself)?
Also, if I need to replace the seals, does it make sense to replace the bearings at the same time? Are there any other parts I should consider replacing while the engine is apart and the case split?
Thanks.
