I did the ohms testing and something is very odd. The pickup wire shows 135 ohms. The excitor wire shows 390 ohms - but only for a split second, then drops to zero. I did my original testing based up this video, which basically says the ohms test may not be the best way to test chinese scooters due to the variation in what the various manuals say the ohms should be.

Testing volts based upon the video, I get 44vac on the excitor - which had the unusual ohms, then dropped to zero.
This cart runs exceptionally well up to about 1/2 throttle - that's when in bogs down. Can this be caused by a valve adjustments; or if that was the problem, would it run poorly throughout the throttle range.
Thanks
