Modern Vespa

So I watched Robot's video and took a crack at flushing the brake fluid on my 2018 GTS. Not my first rodeo, I've done this dozens of times on other motorcycles. Holding pressure I opened each bleeder and very little fluid came out. Certainly not the pumping action I've seen in the past on other bikes. Does this have anything to do with the ABS?

Curious, did the other bikes have abs?

Fortunately, (at least for maintenance purposes) no. I understand the need for greater sophistication but not being able to do basic tasks without going to a dealer is frustrating. On my Ducati there is an annual service light reminder that can only be cleared with a $900 computer tool.
I'm afraid I'm in the same boat with this Vespa ABS.

Changing the fluid in a GTS ABS should just work without going to the dealer.

Whereas getting air out if you got some in ... Not so fun

And for the Ducati use (a lot less than 900) https://www.obdstarstore.com/wholesale/obdstar-iscan-ducati-motorcycle-diagnostic-scanner.html

In German but works great to get air out

Good video but I don't have air in the system, just can't pump fluid through the ABS unit.

Seems needs a mightyvac pretty similar to video I imagine as reported in thread below.

I can try that

Hope it works
