Nissin Front Brake weak

['18 Novvy]

Hi all,

2018 EC300 - Looking for tips on how to improve the stopping power of my front brake. I only bought at 50hrs and have done 15 of my own. I'm sure when I first rode the front brake was strong but now it definitely can't do a stoppie.

The brake lever can be firm but two fingers will get it to the bar. I assume when it's working right there's a firm limit to the lever travel?

Things I've tried:

• Bleeding with stop/go technique
• Rebuild front master cylinder
• Bleed full line of fresh fluid with vacuum bleeder
• Push pistons back a few times, to get any bubble into the main line

So far I haven't had a major change in brake strength. What am I missing?
