Hi Sandeep,
AFAIK, the pulley diameter is measured on the outside edge, so just the biggest diameter of the wheel.
Mine is 145mm.

In my limited experience since the cyl. head temp measurement device is on, outside temps have hardly any effect on cyl. head temps.
Outside temp (environmental temp) does make a dramatic difference on oil temps, but not to head temps.
Can't logically explain it, but thats it.

Regards,
Walter
