Just had a freak accident with my blackbird after picking it up from a garage.... The garage changed the rectifier and after riding it 20 miles I stopped.......
Went back on the bird, and pulled away slow, then all of a sudden went to high reves flat out without touching the throttle Bike went straight up in the air and chucked me off and knocked me out, has anybody got any ideas?

Been a rider for 26 years...
Cheers
