hi all, just recently returned to motorcycles after marrage, kids divorce etc. purchased a secondhand 1983/4 bmw k100. all was running ok until i accidently hit the kill switch whilst reversing the bike with the motor running. since then it wont start. there is electrics to the dash and too the started button but the fuel pump is the only thing that works but there is no ignition? i have checked the fuses but not being all that familar with the k series i am in the dark. any leads? cheers, wayne
