Xplorer 300 mystery hose

Brand new here. Bought a used xplorer 300 and have been replacing warn parts with new ones. Found a hose attached just above the oil dip stick and the other end is melted and not attached. It has length to reach the carburetor but no obvious place reattach. I am assuming it is a oil return line but it's been awhile since working on a 2 stroke. Any help is appreciated.

So the hose travels from the dip stick on the right side through the inside past carb area and into the frame on the left side? I have 1 nipple there being occupied by a carb hose. This nipple is just a solid piece that caps a vacume hose. I am not sure we are talking about the same hose. My hose is not long enough and I am not sure a thin hose like this runs that far anywhere. It's not thick and durable to handle any heat at all. I appreciate the try. Any other possible suggestions?

It's the transmission vent hose - without a pic, I'm not sure what hose is "capped", but neither vent lines or vacuum lines are "capped". The line from the carb to the nipple should be a float bowl vent. The vent hoses are simply located high up on the frame to prevent water from entering through the vent. There is a nipple on the bottom of the carb that is supposed to have a line attached to it to carry overflow away from the engine area - that line is supposed to have a one way valve in it to let overflow out, air in and prevent water from entering the carb during momentary encounters with deep water.

Old as Dirt, I have come across some more mysteries. I am replacing the starter and think I found the counter balance vent you spoke about. I circled it in a pic. Also found a thin white wire with a thin red stripe coming from a cluster in the back of the pull start case. Is this for the start button? The oil injector was bypassed by previous owner and I found a thick red wire and thick tan wire spliced together on the left side coming from the front wiring panel. Any thoughts? Anyone else have any thoughts as well?

Wiring on the 96 Xplorer 300 was pretty basic
red with a white stripe is switched power (hot when the key is on)
white with a red stripe is the control power wire from the starter switch to the solenoid
brown is ground
black is ignition kill

There was no tan wires - here's the color code
155900


In your last post - there is no device in the wiring diagram with 2 red/wht wires going to it - I have no idea what it is or where it goes - might be year model specific
