Ok excuse this question as I am sure there is a really obvious answer, however. On the side of the carby the two throttle cables are connected to a part that controls throttle opening and closing. Idle speed is controlled by a adjustable screw, WOT is controlled by physical shape of this part.

Now my question is can this physical piece of metal that controls the maximum amount that the throttle is opened be moded (ground back a few millimeters) to increase the throttle opening?

Does that even make any sense?

 

Now I'm not totally clear on where you're going with this, but are you saying that you believe the throttle butterfly is not opening to its wide open position in stock condition?

 

No it can't.

 

Another customer looking for the "magic screw" That only us mechanics know about.

" I have this moped. It only goes 30 mph. Is there some screw I can turn to get it up to 45 or so?"

Sorry,,,,,

You didn't finish...45mph and 200mpg.

 

I believe that's what the OP is saying.

OP if you've ever seen the butterfly with the carb off you will see that it is full open at WOT, therefore grinding the bracket back will not do anything except for damage the carb probably.

 

Thanks PSUdude85, thats what I was trying to allude to in a not very clear, know very little about carb terminology kind of way. I was told that straight from the factory a throttle restriction was in place and I figured this may have been how they did it??

 

I don't recall any type of throttle restriction, but there is one hell of any engine restriction which can be solved by removing airbox, rejetting the carb, and adding an aftermarket exhaust to it!

 

Just clarify for Noralup- PSUdude85- intended to say remove the airbox lid you do NOT want to remove the whole airbox.

 

I'm going to verify 100% whether or not the bike can go 100% wot, or not ill post up my results after work.
