Default Mushy lever after full LBS bleed?

Had a full [badly needed] complete bleed done on my '93 1000F last Fall at the Honda dealership, and then put on some nice 6-click ASV levers.

The problem is, I'm still getting a mushy front lever, which is disconcerting enough to not be riding much.

I've checked the pads...plenty of wear left all the way around. I also regularly clean both the front and rear discs.

Possible culprits:
  1. OEM rubber lines need to be ugpraded (at least for the 4 front activated / outer pad lines) to Spieglers? A full set of these would break the piggy bank.
  2. Bubbles in the lines...re-bleed needed?
  3. Cheap fluid?
  4. They bled the system in the wrong order (important per the Haynes manual)??
All suggestions or thoughts welcome...I'm almost read to see if the OEM brake lever has any effect (wouldn't expect it to)??

item #4 most likely since it's a linked system which is a bit of a pain in the rear to do.

I would at least try bleeding again, as the manual states. Dont forget the orifice on the forks. I think some said they did not open the orifice, but the manual says to do it.

Honestly, I had the same problem, but with my rear brakes. I bet I went through a gallon of brake fluid bleeding trying to get it right! I ended up putting teflon tape around the bleeder screw threads, and using a vacuum pump.

93 is old enough, that I pesonally, would replace the lines with braided SS. If you shop around there are bargains to be had. Have you taken it back to the dealership where the work was done? Often allowing them to address the issue won't cost anything more, if you politely point out that you paid them once already. (Especially if there are other customers in ear-shot). ;-)

Too right there Ronnie .......teflon tape is the way to keep the air out and save
using gallons of fluid ....... Big + 1

Bleeder vac , such as Mity Vac can help speed the process a bit but the ole push and
release the pressure at the nipple always works best at the end

Thanks for all the input, gents! My order of attack will proceed thusly:

1.) shame the dealer into re-bleeding...maybe bring along some fake 'customers' ;-)
2.) shop around for some braided lines
3.) do the full bleed by the book myself, installing the (6) speed bleeders I bought last year

Time to get out and ride...cheers!
