Hi Javier,
The original throttles and the V7 throttle look exactly the same on the exterior, but the V7 throttles have the 'R or L' markings underneath the throttle as seen here and have a torsion spring. The original throttles do not have the 'R/L' markings and have a helical tension spring inside.
We take these concerns very seriously, so we immediately coordinated with our technical team and fulfillment team to find out the facts about this specific situation. This is how we discovered that the unit is outfitted with the V7 throttles- like the new throttles, they are an upgraded component that solves the issue of the original throttle.

Rather than spreading baseless accusations of malicious intent on our part, we appreciate everyone that comes to us directly to communicate their concerns. While issues do come up, our team is always ready to help our customers to find the next steps forward.
