Anybody know why a 03 Husqvarna TC450 would have a hole in the ignition side of the case to were you can see the crank move. I removed the ignition cover to check for water and oil came running out. I looked inside the case around the flywheel and the upper right corner there is a hole to the inside of the crank area. Is this a factory FU or what ? Most bikes I`ve seen are sealed to the inside. I really don`t know how this bike has even been running like this, cause every time you`d lay it over to the left oil would be sloshing in. Any Husky mechanics out there? It`s a machined hole. Can I just plug it with a dowel or something?
