I could add the contrast between the frame that's built like the Forth Bridge and the mean metalwork of things like the rear steel fender without a beaded or folded edge, the chain guard that rather than being a "U" channel section is a poor "L" section.
Also the rather thin cables used for such things as the headlight wires, a whole 1.3 volts are dropped in the wiring wasting a fair bit of light output. The far from weatherproof items like the starter relay and oil light switch, etc.
So, to re-cap this thread, apart from:
Crappy thin wires
Cheapo starter relay
Wafer-thin rear fender
Chain guard offering zero weather protection to the chain
Possible dodgy footpeg mountings
Useless front and rear suspension
Fast wearing rear brake pads
Marginal battery power on EFI models
Lame sounding OEM exhaust
Flexible seat pans crushing igniters
Weak breathers and starter idler gear bosses on earlier models
Snatchy throttles on EFI models
gear shift system
The crank position sensor
all the attention you get
The bike's great...
I love mine dearly with all its faults though....
