Last night on commute to work, doing 70 in center lane bike seemed to be bogging down. I tried to throttle it and get off the road, but no openings and by that time, the front tire was locked up tight and I was at a dead stop. At this point I hadn't touched the brakes in at least 3 miles. I got hit lightly from behind with all 3 lanes coming to a halt. Now Im in first just trying to get the bike across 1 lane, still locked up and wont go. back tire smoking etc. A couple guys came running and they pulled on the front wheel while I pushed and we jerked it off the road. Now no response in gear, either final drive is toast or clutch or both. After police arrive and call for tow truck, I was going to put it on the center stand to walk it sideways to get it further off the road when low and behold front wheel now perfectly loose. What the! This is a 94 without abs. A few weeks ago the front lever seemed a little tight, (but only when I parked it in the sun) so I changed brake fluid and it seemed normal again. Any Ideas where to start? I'm not so sure It's worth fixing, but at least I wanna know why it happened cause It could've been bad. Thanks, Bob
