What causes the abnormal noise in the Storm Eye 190?

[LeParker]

The abnormal noise in the Storm Eye 190 may be caused by insufficient clearance. Methods to address the abnormal noise in the Storm Eye 190: Prepare the necessary tools, including a large cross-head screwdriver, a 5mm hex wrench, a small flat-head screwdriver, 8mm and 10mm open-end wrenches, two 5 or 6mm screws and nuts (the longer the screws, the better). Use the cross-head screwdriver to open the left-side cover of the bike for easier access. Take out the tensioner with the upper side facing you, rotate the tensioner push rod counterclockwise to extend it—only rotate it half a turn (180 degrees). Then align it with the slot on the lower baffle, and finally reinstall the previously removed spring ring. Note that the slot can only be aligned at 180 or 360 degrees. Disadvantages of the Storm Eye 190: Lack of strong power, dim headlights, and somewhat slippery tires.
