Possibly, but mine was derestirceted to start so no comparison

I don't know where you are so there maybe factors to get different results than mine, but I average about 104 to 106MPG.

Highest ever was like 107MPG and lowest ever was like 84MPG recently but that was after it sat for a couple of months and before I got to clean the carb and it wasn't running proper.  cleaned and new plug and my last fill up was again 104MPG. 

When I drive and the roads I drive it is normally wide open throttle or idling for a red light.  very minimul time when throttle is less that full throttle.

When derestricting your boss you will improve your MPG. This is because your scoot will be allowed to enter a higher gear now that the boss is smooth and not restricting your gearing to a lower gear ratio.

However an increased jet size will allow more fuel to flow into the engine decreasing MPG.

I have only changed my boss. I have not changed main jet yet. I consistently get well over 100MPG and an indicated 47mph on my speedometer.

From what I've heard from others, even with both derestrictions done you still have increased mpg.

Change your drive boss! It really is the easiest thing to do and the benefits are unparalleled.

The 47mph on the speedometer is not actual. They are off by a few miles per hour about 5

I realize this. Mine is about 15% off. When is says 70 km/h its actually 60 km/h. I was just stating.

How much you will gain depends on how much you are already driving per liter fuel. Usually a 70% increase can be seen because of the higher gearing and because you will more actively use the throttle to control the speed and by that only give the throttle needed to hold the wanted speed, compared to when you are restricted and most people have a tendency to over-throttle to hold the speed at the highest. :)

Yes, when the road is big and straight, but it is not everywere that 70 km/h is safe, so i guess that WOT is for most people only used for accelleration or for driving on the bigger roads that are made for 80 km/h cars.

The most important thing in traffic (and specially on a two-wheeler) are as we know, to drive according to the conditions. :)
