I don’t think Korea had options nowdays anymore to change pulley sizes for the GV

So to reduce the RPMs on rides , you will have to switch to chain kit.  And use 1 tooth larger front sprocket , as rear sprocket for 650 is only 1 size (at least here in the UK supply chain)

But PBI America can probably make custom sprockets for you in sizes you desire.
