I see in the owner's manual there is a throttle limiter you can unscrew and pick up some more power. Has anyone done this and has it helped in the top end speed? Just wondering if it was worth messing with for a few xtra MPH.

 

Mine was already all the way out. You can look at it and see if it's limiting the throttle or not.

 

where is it at?

 

Right by the thumb throttle, it's a screw.
