I'm the proud owner of a 76 KZ400. I picked it up at a garage sale about 8 years ago, pushed it about 8 blocks home and have been trying to get it to run reliably ever since.
I finally got it going this summer but it's leaking out of a hole just above the front sprocket and that in turn is getting on the chain (not bad) but the chain is spraying that side of the rear tire (not good).
I've been searching forums and schematics but can't locate the part. It looks like it's just a plug that goes in the hole but I don't want to put something in there that might melt or disintegrate and fall into the motor. Any help or suggestions would be appreciated. Thanks!
