Few reports lately where the rotor casing wasn't fitted with the 2 dowels that locate it properly, this caused the casing to sit a little skew and that caused the rotor itself to start to catch on the stator and the field coils. Any sign of rubbing on those? Also make sure the dowels are in place. If they are missing when you look, unless you know they are meant to be there you'd not know they were missing.This is exactly what happened to mine, you MUST have both dowels fitted.

If you do find the dowels are missing Brian, I have some here. They are No.11 on the fiché (Attachment Link)
UPDATE:I now have bike sorted.My mechanic ( now ex-mechanic) installed the new regulator/rectifier incorrectly, in fact he did not install the one I gave him at all, he used a rectifier he had in stock but still managed to wire it up incorrectly.I got an auto spark who sorted it.I took bike for a 25 mile run and then using an IF temperature gun, I measured the following temps.:Fins ; 120 ocStator/Rotor side casing 72 ocelectronic ignition side casing 68 oc.This all seems normal.Bike is running really well, I have to install the spring on the choke rod for the carb yet.I can get bike easily up to 80 mph but not much there after.Idle sitting at 1200 rpm.Thanks for all your helpBrian
