Hey guys I recently bought a 2007 Baja wilderness 250 for my younger brother. After 2 days of riding it the transmission started leaking fluid and the quad only goes in reverse not forward. The chain also became loose. Any idea what could b the issue here. Thanks

 

output seal and fliud is down

 

Where is the output seal located? Not too familiar with quads? Also what kinda of fluid does it take n where do I install it? Thanks in advance for all the dumb questions

 

The output seal is where theshaft that drives the front sprocket is. The fluid really depends. There is a few different set up's is the fluid red or brown? thats leaking
