spongy front brake lever

Took my Wee to local mechanic to install extended stainless steel brake line for handlebar risers. Before dropping off, the brake level was engaging very early.

When I picked it up, it was waaay soft. Rode it home and used Velcro to hold the level to the grip for 18 hours. The next morning it seemed to do the trick. But it returned to its spongy form. I use two fingers to brake. In its current soft form, the brakes engage about half way through the level action but do not apply effective stopping until the level is touching my remaining two fingers.

I returned to the shop and talked to the mechanic. He noticed they were soft and brought it to the owner's attention. In his experience with Suzukis, he noted that after the first brake fluid change, all Suzukis have a much softer feel. They dialed it to 1 and even bled the lines 3 times (upon further questioning about that, three different locations and times NOT all locations 3 times). The mechanic said they topped off the brake fluid.

It is not acceptable to me to have to use all four fingers to brake because I have to pull the level almost all the way to the grip to get full stopping power.

I've read several threads about this on Stromtrooper. I'm left to think of two things. One: they didn't push the brake calipers all the way back in off the rotor. Two: air in the ABS actuator. (Hoping not as it sounds like I'd have to pay for trip to Suzuki dealer). When I asked if the bled from ABS, the mechanic said they did.

Any other ideas?

Sounds like you need a different mechanic. If changing the lines made it worse than before then there is definitely still air in the system.

I am not experienced with bleeding the ABS unit but apparently it needs to be actuated while bleeding the system to get the air out of the unit. Most likely the current shop did not do that or not properly.

I changed the fluid and lines on my Wee for the first time recently. Just as firm now as before. Send like it's be suspicious about this mechanic. You might just try bleeding the brakes yourself, it's not rocket science.

Air bubbles rise. The air is way up in the hoses and at the master cylinder. It needs to be bled at the top, not at the bottom at the caliper.
