I changed the oil for the first time today.. When I got the bike the oil looked fresh but I didn't have any idea what was in it..... So I ordered a sump filter, the secondary filter (I guess that is was it's called) and gaskets..... Low and behold as I stated in other post some people shouldn't have tools..... I found rtv silicon in the sump area were some one didn't want to buy or make a gasket for so they used rtv... Gaskets are cheaper than the rtv...... That stuff was all squished out on the inside... Any one ever see what happens when that crap stops up a oil passage oil makes it to some bearings...... I haven't on a motorcycle but I have on a automotive engine... Here are some pick of what I found... Also how much oil are you guys running in your some say half way between the low and the full mark so it don't blow out as much through the vent...
