After some unsealed road my ABS and MGCT warning lights came on and stayed on. The MGCT light flashed fast at certain revs throughout. I stopped the bike and had a look at the ABS tone sensors and noticed the rear wheel sensor was less than 1 mm off the tone wheel. This seems too close as in the manual it says 2-3mm. How do I adjust it? I did take out the machine bolt and had a look all seemed fine. Then screwed it back in and it sat back at 1 mm from the tone wheel. Wasn't aware of any damage, I did take it easy on the unsealed roads. Also noticed that the MGCT is kicking in when I down shift. Could this all be affected by the one problem? Any help would be appreciated. Pat
