Hey guys,
Quick question.

I purchased a 2008 1098. Pulled all the body panels off to given it a once over and to detail the bike.

In doing so i i realized the vent hose that comes off the upper left side of the motor and routes down to a flat pinched end sticking out center of the lower fairings just behind the front wheel had been melted and cut from the header.

My question is: I bought a few feet of replacement hose. Do i need to route this or is there a vented cap or such i can use instead?

It's a water drain hose from the airbox. Simplest solution would be to trim out the burned piece and add a piece of hose with the valve on the end using push in joiners. The top end of the hose where it attaches to the airbox is very difficult to access and has a special end molded onto it to fit the airbox outlet. There are also two different types of airbox outlet fittings.

Good advice right there. You should probably try and retain the squashed-end, so dust won't get into the pipe and airbox. These things suck seriously at revs.
This hose traverses a fairly difficult route, and of course comes off when the airbox is removed. It is in a very tight corner to re-fit, and becomes a bit gooey and slippery over time, and may split where it mounts to the airbox.
There should be an openable plastic retaining clip glued to the side of the oil cooler to guide it past the hot bits. These fall off, so a quick clean and re-attach with silicon adhesive sorts that.
And of course it needs to fit the slot in the bottom fairing.
A little tip on this - flatten the curved/pointed inner edges of the slot in the lower fairing with a flat file so it is easier to slip in and out.
You will be trying to remove/refit this rubber and hose with a shiny fairing panel in one hand, and this makes it easier..

Just in case you're not aware Pat, the early bikes did not have the valve on the end of the tube, nor the slot in the lower fairing. The tube was just left hanging out the bottom like an umbilical cord.

Also the early bikes have a hole in the airbox for a grommet style fitting on the drain tube, whereas later bikes have a small protruding plastic tube out of the airbox which the hose fits over with a clip.

2008 should be the same as mine.

Done a few of the same year.
