#$%@ GP Bikes just made my life harder

Yeah, dry sump engine. So you have to drain the oil reservoir first which is actually quite easy - nice 15mm bolt in an easy to access spot, but the other 2 bolts are in the sump to drain out a few low spots I guess. They're oddly close together but both seem to dump quite a bit of oil, so it must be a divided cover somehow in there. You also basically can't see them at all, so I use a stubby box end ratchet wrench, get it on the bolt by braile, and once they're broken loose then you have to take the wrench off and thread them out by finger - if you left a box end wrench on and used it to thread them out I think you'd run out of space since the frame is right there.

You also have to put the front wheel up on blocks otherwise you can't even get the drain pan under the bike much less a wrench.

Then there's the refill procedure - 3.8L or something like that goes into the oil tank fill port (which you need to remove the seat to get to), and then around 2L goes into the crankcase fill port.

Hey, at least the oil filter is really easy to get at lol.
I had a Polaris sled with a dry sump 4T engine. Oil changes were so easy, just syphon out the oil from the box and refill with new oil, pull a oil line and crank over the sled and it'll pump out the rest of the old oil in seconds then just top off the box. It was a 5min procedure.
 
Wrap aluminum foil around the frame before you start.
As for oil on yourself......latex gloves & tight wristbands.......lol.
I haven't seen his situation but I often find myself using paper or tinfoil to make disposable chutes/deflectors/funnels when manufacturers made life difficult for me.

It’s thankfully not in a place where it runs far so I just wipe things up afterwards. And yeah, I wear gloves while doing messy work like this, but going wrist deep looking for a drain plug in the pan while simultaneously releasing a string of curse words is still pretty messy lol

I use puppy pads under the bike when I’m doing oil changes so any errant drips are nabbed. They work great and they’re cheap at the dollar store.
