Help please my 7 year old 250B cruiser just cut out on me on the way to work! I bought her 6 months ago and was running good, there is no spark at the plugs, I checked the 12volts into the coils OK and tried a couple of new coils from a 250 virago but still no spark....boo hoo, anybody got any tips for checking the CDI igniter unit and timing switches? also is there any workshop manuals around that i can buy? I was really enjoying riding again after a long layoff so please help, cheers from Dorset biker
