I have a '99 kx250. the bike runs awesome, but I notice it spooges a lot of trasmission lube out of the transmission breather tube located on the backside of the kickstart housing. I use Maxima MTL 80w tranny lube by the way. Why do you think my breather tube spits out so much fluid? (I have to top off with about 1/4 quart every 3-4 hours). is this normal?
