Hi. I bought for my 1980 R45 a Koso cafe racer speedo/tacho from digitalspeedos.co.uk
I have had it about 12 months now, and whilst pleased with it, have never been able to stop the tacho needle fluttering. (It ticks over between 500 and 3000 revs!)
I have looked on the internet and there seems to be many people with a similar problem on various bikes when using aftermarket tacho's. I have tried wrapping the tacho wire around the plug lead, re-routing away from other power cables, Connecting to + & - coil outputs, Fitting a large resister to the rpm lead all to no avail.
Today I solved the problem. I cut the rpm wire and fitted a small LED. (My son had bought a small light up christmas tree construction kit from maplin and had an LED left over)
Just took it for a test ride. perfect. No flutter at all. No delay. Just a perfectly working tacho
Thought i'd share this incase anyone else in the group has, or have had, a similar problem
Jon
