I have just bought a winter project, 1982 Yamaha sr250, on checking the spark when I press the start button I get an immediate spark then nothing untill I stop pressing the button and then a few seconds later I get a single spark, WEIRD.
the starter motor is a little worn/slow, would I be right in thinking there's not enough turn over speed to generate a full spark? I was thinking maybe if I bump it down the road.
any help appreciated.
Cheers
