New Moto Guzzi Door Mats Available Now
I realize it's not a Stelvio, but this is what I came up with for my Sport. Small fuel additive bottle modified to fit under the gearbox drain and right into the drainpan. Something similar may work for you. Paul B
I just use a carefully shaped channel of aluminum foil - it handles the job pretty well with little effort or cost.
I have a 'form a funnel' which is a lead sheet covered with some kind of rubber. $10 on Amazon.That being said, I don't use it. How I change the Stelvio oils-Run the bike for 10+ milesPut on bike lift, drain CARCPull gearbox plug, let it drain all over centerstand into panPull crankcase plug, drain into pan, pull filter.Cleanup, find all the crap I dropped in oil drain pan, re-fill.It takes just as long to clean up as it does to prevent the mess in the first place.http://stelviontx.blogspot.com/2015/11/fluids-change.html
