came across this what are some opinions on doing it this way.

Looks like a good technique, so long as you have forearms and grip like "Popeye"... LOL! Being faced with a 20-mile walk might just muster enough adrenalin to git er' done!

On my 50cc short case, I can just get the belt over the crankshaft with the clutch compressed. So I have one of the Harbour Freight emergency 12v impact wrenches I carry along with a spare belt, easy to change on the side of the road if necessary!

You still need to disassemble the variator and clutch to do required maintenance when you change a belt so this is only good for a side of the road get you home fix. Chances are that you will do some damage to the cords in the drive belt so that will need to be replaced again once you get home. There are needle bearings that ride on the clutch shaft that drives the gearbox that need to be greased every time you service the belt so that will still need to be done or you will get harmonic vibrations from the bearings not being lubed which generally causes muffler and rear body frame failure. Also as mentioned the rollers will also need to be cleaned and checked for condition along with proper orientation in the variator.
A short term solution to a stranding however its not a good practice to force the belt over the pulleys as part of a normal belt service.
He keeps erroneously mentioning not having to remove the variator bolt (corrects that later to nut) by using this method however by the book you remove the nut on the clutch first followed by the clutch bell next remove the variator nut and outer drive face and then the clutch itself with the belt when servicing the belt followed by the rest of the variator assembly. The claim is also made that the lack of sharp edges on the variator makes it so you can't damage the belt however this is not correct either as the cords will be malformed by bending the belt sideways which it is not designed to do effectively putting a sideways curve/bend in the belt to one degree or another which again causes additional driveline vibrations that are potentially damaging to the bikes exhaust, cvt components, frame, etc. Even if the belt does not fail completely there will be to one degree or another additional fatigue to the rest of the bike which you may see as mufflers cracking, wheel guards/inner fenders coming off, exhaust flange bolts pulling from the head, spark plug boot failures or air box failures which many times most will simply chalk up to bad Chinese quality control instead of a damaged belt.

The method works well if stranded with a broke belt and one needs to use a little common sense to make sure everything stays in place. On most scooters one needs a 10mm wrench/socket to get the variator cover off and I've did this myself in this video. Had no issues.
