[QUOTE="lnewlf, post: 1289338, member: 9707"] don't know about GenI but if I remember correctly a Gen II ABS trigger wheel has 42 teeth....x@800tire rotations/mile= 33,600 ppm...easily handled by the Rostra.. I don't know how the 80,000 ppm for the Gen I was arrived at [more teeth?]......but in a hail mary attempt to cure the random dropouts on my GenII I tried a 4x pulse divider which did no good whatsoever. I did find however that as might be expected the dip switch setting must be reduced by a factor of 4 to 8000 ppm [@ 33,600 divided by 4] or the CC was very rough. FWIW....for my bike most of the problems were a result of the occasional abrupt throttle response which wigged out the CC...disconnecting and grounding the blue tach wire cured all. [/QUOTE]
