Most motorcycle problems are caused by the nut that connects the handlebars to the saddle.

I've fitted fireblade coils to my bike, I now have a big space where the old ones were. Does anyone think that this would be ok to relocate the rectifier to this space better ventilation etc  my year old rectifier has died again.

Should be fine. You just need to make sure you use suitably thick cable and do the joints/insulation properly.

Thanks all, yes R1 MOSFET rectifier, thick cable, joints soldered, wired direct to battery and up front in the breeze im hoping that sorts it. All info on fireblade coils in the upgrade section, well worth it picks up much stronger.

The SH775 Series R/R from Shindengen can be sourced from Polaris dealers at about £70. It is only suitable for engines which rev to about 10000rpm. Above that there is a later Shindengen series type, the SH847AA which is more expensive. It was first used on some Suzuki models in 2014.
