Bloody hell these things are like *hit of a shovel

Just love this bike, looks great, sounds awesome, handles well and best of all ITS FUN

Now down to business, have read a lot about its 2 main faults. Rectifier is a no brainer, just change it out. Not so sure about the cct’s, what’s best leave it as it is, fit new auto ones with stops or go for manuals?
Any other advice, hints or tips about the bike will be much appreciated. Off out on the bike now as the sun has just popped out, feel the need to exercise my right wrist (keep yer mucky thoughts to yerself).
