Things to check - am sure you've already done this though: Both rsv's of the mc full? Checked rear wheel cylinders for leaks? The sensor is tripped, that's a given. Only way I know to reset them, without the tools outlined in the shop manual, is to do all the above, then when you're certain the system is leak free, stomp on it. And it sounds like you've done that. Did you switch the front lines to 3/16" rather than the original 1/4"? (That SHOULDN'T matter, only affects pedal feel and work accomplished per amount of pedal travel, but I am curious). Did you buy a disk/drum prop valve or factory-like distrib block?
