Curious minds want to know… Is it normal for this oil to get on the swingarm as well? 'Cause this morning I looked and it's gettin kinda speckled.
samuel, If the speckles are on the LH arm, that is chain assembly grease or chain lube, depending on how new your bike is.
There have been one or two people who have not squeezed enough oil out of their freshly re-serviced air filter and a day or two later post that their left rear wheel bearings appear to be leaking oil.
It was just the excess air filter oil dripping on the rear inner fender, then dripping on the swingarm, running across to the rubber slider, then down and under the arm, to finally drip on their garage floor.
One could attach a long hose to the Dirty Air Box drain and route it down to where the Clean Air Box drain used to be, but do not plug it.
While we are down here with the drain hoses, do you see that black hose tie which corrals the hoses? It stabs into a hole in the frame pipe. There is also a hole in the frame pipe on the Left side of the bike.
We need to remove that hose tie and then use silicone RTV sealant (or screws) to plug those holes to keep the water out. When water gets in those holes it rusts the suspension pivot bolt and then when one wants/needs to remove it it turns into a REAL Fight!!
The steel hose guide on the top of the swingarm is all the hose guide that is needed.
One can read more about the 2 holes & suspension servicing over on Toms Souperdoo site, https://www.souperdoo.com/stuff%20th...-zerk-fittings
ps, Your existing melted hose may be long enough to cap the forward nipple quite short and still be long enough to drain the rearward nipple.
As I remember the factory left that hose hanging down in the weeds & rocks lower than necessary anyways.
