No Spark...

#1 Post by speedfrk » Mon Jul 19, 2021 6:56 pm

84 US spec RZ350. This is the bike I've been working on for a while, off and on. Got everything mounted, PV adjusted and checked the spark at the plugs and, nothing. New plugs, caps. This had an aftermarket throttle tunnel since it has VM32's on it, so no kill switch although I ordered an aftermarket to hook up since I don't like not having one. But I'm assuming it doesn't need to be there since the bike was obviously running previously. I know the 84 CDI's have a bad reputation so maybe it is bad? Anything simple I might have missed? I've checked the grounds and all seems good. The other electrical stuff all works.

Turns out it was the side stand switch... I jumpered the harness connection and voila, spark! You gotta love old bikes otherwise you'd hate them.
