Yeah Kisbee i got that exact RAC one that Argos sold. They stopped selling them now tho, at least in Scotland, so i had to get mine from ebay off a guy in England for about the same price.
Ive taken my variator nut off and on at least 15-20 times using it and had my clutch off 5-10 times too. I usually give it 5-7 impacts aft i gwt it hand tight 1st. Been fine for me, ive had no issues or problems yet. The RAC one comes with a socket that fits the variator but not the clutch. I just use a standard socket from my socket set on the impact wrench for the clutch side, been fine with that. Think its a 14mm if i remember for the clutch side.
I def got my moneys worth from it over the last 6months, changing belts, rollers, variator, clutch, and just for taking it all apart to clean iy out now and again.
I tried the spanner on the variator trick off youtube but couldnt do it and i didnt fancy putting it back on with that method. Threadlock wont stop you getting it off again, just stops it working loose, a bit like a nyloc nut does. Just put a small drop on the threads, not too much or it will get into outer variator and its harder to get that off. Saying that i always end up with a little on the outer variator behind the.nut. No prob tho, just waggle the variator side to side while pulling and it comes off, i paniced at 1st time i tried, thought it would never come.off after i removed the nut!
Do it yourself and you will save a fortune over the years and you get to feel like a real mechanic
. I knew nothing about scooters till i got my Kymco, now i always have a go to fix it and only go to a mechanic if i cant fix it myself.
Check the rollers, variator faces, clutch, belt and give it all a good clean out with a paintbrush and maybe some electrical spray cleaner if its oretty grubby.
Good luck. Get that xmas list to the wife asap
