So today I decided to ride my 640 adventure to the store. Haven't ridden it in a while. A few miles down the road my left foot feels wet. I stop and find the oil window cracked and oil squirting out. On the way home I convince myself this happened in the garage since the last time I rode it. I get my 4 year old out, take him in the garage and he fesses up to it. He said he put a scratch awl to the glass and hit the back of it with a wrench. I believe the case cover can come straight off with no problems? And a new glass should be fairly straight forward to install right? I'll have to change the oil also I suppose, it was do any how. My manual for the bike is a cd and I do not have a means to consult it. Anybody familiar with taking that cover off who can tell me anything other than the obvious to look out for I would appreciate it.
