Don’t count on it
I have a strange problem on my 1998 Suzuki Bandit 600. The rev counter is very erratic. One minute it’s sitting at tickover, say 1000rpm, then it jumps up to 4000 to 6000rpm then back down again. It does the same when I’m riding it. What could the problem be?

Pete O’dell says: It could be a faulty tacho but a far more likely explanation is that there’s a dodgy earth. Suzuki in their wisdom saw fit to splice the earth wire (black with white tracer) in with three or four others. They’re poorly twisted and soldered together and taped over. I suspect that this is where your problem lies because of intermittent earthing.
