Wait, Suzuki abs is bad because of a lever travel adjustment?
I think what he means is that the lever is able to come all the way to the bars because of the 'squishy' or soft feel (usually caused by rubber brake hose expansion) no matter where the lever position is set to.
This was explained to me by a very well trained factory Suzuki tech like this . . . "The reason why the lever travel is 'excessive'. . . .
(speaking of the amount of travel
BEFORE the brake starts to work,
NOT the 'squishy feel' issue, as explained previously, usually caused by rubber hose expansion or the compression of any air in the system) ) . . . . on the Busa master cylinders compared to say a Brembo m/cyl, is because the Suzuki m/cyl has a larger diameter scavenge port (the hole that goes between the bore and the reservoir) and hence the piston has more travel to slide across that hole to block it, until the fluid begins to really move and push on the caliper pistons.
Also, the 12 caliper pistons have a large surface area compared to the usual 8, to push on so this also exacerbates the problem.
The Brembo's scavenge port is smaller in diameter and the piston has less travel to block off the port and start to move the fluid to push the 8 pistons usually found in Brembo calipers.
Also the m/cyl diameter to caliper piston surface area ratio comes into play as well, if you want more power in the 'push' of the fluid, you need to decrease the m/cyl diameter OR increase the caliper piston surface area.
So the issue is inherent in the design of the m/cyl itself.
I intend to find a good radial m/cyl and fit it to my Gen 1 and hopefully get a better brake feel.
