I bought a set of Z1 parts coils, they sent me the wrong ones, then gave me an address in Sydney to send em back to, then sent me the right ones, 2+3 shat itself within a year, I still have the 1+4 coil on there, waiting for it to go too.
The plug caps they came with were total #$%*, the brass screw that screws into the lead snapped off on the first two and I then just chucked the other two.
I once bought a set of reflectors from them, supposed to fit cb750 fork ears, the thread size was wrong and they cam with a nut but you couldn't put the nut on the inside of the fork ear because the fork tube would not go in then. I emailed them and they said I was the first to have a problem, #$%* that place, never been back.
