I'm probably going to get into trouble with someone for revisiting old threads.
But I promise only to pick good ones!!
Anyway, the guy in Japan seems still to be in business, at least his website is still up.
FYI, if you have done the LED diagnosis with the middle blue plug and seven blinks tells you it's the brain, and you've done about 40 resets and the lights still flash - you can still find functioning brains on ebay. I got one sent from France for around $215.00 CDN postage included and connected it where the old computer was and after one reset -- no more blinking red lights! Yaay!
I tried to lock up my rear wheel on gravel last week and it wouldn't lock, just went clunk - clunk - clunk which was funny because the freqency on the old ABS 1.5 (ABS1) is so much slower than in modern cars. But still: did not lock up the wheel.
I was however, not sufficiently courageous to try out the front wheel.
