i posted a while back explaining how my 93 blade simply loses power (to the engine, the lights still work) after a not so prolonged duration of time. i've listened to it with my helmet off and right before it loses power, the exausts tone starts sounding like a crappy harley. then it dies. when i try and start it, the starter goes but the engine doesn't turn. then after about 10-15 mins it does and i can ride for another 2 or 3 miles. Anyway, i had a friend clean the spark plugs, i got a new battery and a new rear sprocket. my blinkers wire got cut, don't ask me how. do any of these things sound like they could be the problem? this certified tech thinks i need a carb rebuild which i probably do. why does my bike die so much??
