Where do these two fuel hoses go?
« on: February 21, 2020, 09:05:38 AM »
I bought the bike without any of the fuel hoses attached and I just installed the carbs yesterday after getting it rebuilt. I am ready to start the bike for the first time, I've searched the board but I can't find anything on where these two hoses are supposed to go? They are the smaller diameter hoses compared to the larger 5.5mm hoses that are going to the fuel petcock. Thanks

Air vent tubes. on my K2 they just go over the air box not connected to anything.

Ok, over the airbox and vent to air. Thanks!
