96 KX250 splitting cases
Tonybeau:
First time I've gone to change the oil on my 96 KX250 and looks like the last owner messed the drain hole threads on the case. :-( Going to attempt to repair with a helicoil however think I'll remove the engine and split the cases to ensure its done right.
As I'm splitting the cases anyway I'm looking for advice on what else I should change whilst I'm in there such as gaskets, seals, bearings etc?
Foxx4Beaver:
might as well replace every bearing and every seal...then go over the entire tranny, gears, shift forks, shift drum, shafts...replace anything that looks questionable.
buy all new snap rings too.
doing this now, could save you from having to do it later, and it will make it that much more of a reliable bike to ride.

Thanks for the responses guys. That's what I was thinking although was forgetting about the snap rings.
I take it its best to stick with OEM for the seals but what about bearings - are their any aftermarket bearings which are ok to use (and cheaper)?
Foxx4Beaver:
you can use oem seals....Cometic makes crank seals specifically to help issues from E-10 in pump fuels...get Cometic gaskets also....best to just call them and place orders on the phone...

I've gone next door to my local bearing shop a few times in the past, and had them make me up some bearings for far less money, but typically get oem if they're available.
