Found this video for roller weights replacement.
As you can see, you can use this impact wrench to remove those nuts for roller weight replacement, or belt replacement, or clutch work on your CVT scooter.
Youtube video....
Very interesting comment on this tool which was used to remove those nuts on a GY6 engine.( our LIKE apparently is a GY6 Engine)
Also see the advert for this tool. Low price, works off car cig. outlet...can be used for those few times we will be working inside that CVT cover over the life of our scooter. Beats the heck out of jamming tools into the sprocket, stuffing rope into the spark plug hole to jam against the piston as it tries to rise, or that piston stop that is htreaded into the plug hole to jam the piston , all those things are used to break the nuts loose - as some videos show.. Probably work just fine - but I'd be a lot more comfortable using the proper tool on my expensive scooter engine.
