indicators flashing fast?

[baz-r]

sounds to me like you dont have the right amount of load to make the flasher relay work correctly.
if you have no led lights fitted and all are working i bet it is that some of the bulbs are lower wattage (used any motobike indicators?)
iirc a sierra used 2x 21w bulbs f&r and 5w repeater

the idea was when the bulb blew you could tell by the flash speed getting quicker
