leak

I have a 1983 Yamaha XS400 SECA. I don't ever overfill the tank. But I noticed that when leaning the bike on tighter turns gas would dribble through the tank gas cap and run down the side of my tank. Now, I wasn't surprised by this. It's a 40 year old bike so I can only assume that some of...

Hey guys, So I’ve had this infamous oil leak from my grommet that passes the stator wires thru the left side engine cover in my 81 xs400. I’ve tried replacing that engine gasket AND resealing that grommet with black RTV MULTIPLE times and it STILL leaks. I literally have no other ideas. I...

Need advice... I went to Harbor Freight and got their el cheapo one man brake drain kit. The fluid was pretty dirty. Filled up 2 bottles and now it is pretty clean. However, it doesn't work much better. 2 observations: my master cylinder had only the rubber top liner. The diagram had a...
