The law says between 60 and 120 flashes per minute, and 90 is smack in the middle of that. Because they are solid state, they continue at the same rate even if a bulb blows, unlike the old bi metal strip type.

But why the difference in the flash rates with and without engine running Hairy?

hairygit:
Solid state relays rely on clean secure earth's, often an engine running, the vibration will improve the engine to frame earth connection, but many other factors come into play. For example, what voltage are you getting at the power feed and earth that actually enter the flasher unit? Also dirt in the contacts of the indicator switch on the handlebars or the wires from that switch to where it joins the main loom? Maybe removing the old flasher unit and installing the new one has cleaned crud out of a connection and improved continuity, to name just a couple of suspects.

I'll check those points but everything is new - ie, new switches, loom, relay, lights in fact everything except metal work
