Are we talking about the belt cover here or the crank case?

A Heli coil IMO is better then the original threaded hole!!!! Waaaaay better and stronger,, you will noticed what I'm taking about once you insert one!!!!! Good luck and you will mostly likely be spending close to $30 on a good helicoil set!!!!! Brent said in a thread that the helicoil tends to fail and pops out ? Heli-coils are alright. I've gotten used to time-serts and like them, but most people use heli-coils. I can't say I've never had an issue with a time-sert either.

I'm not saying that you should spend a lot of money on it, but I would re do the crankcase threads with the strongest option that's gonna last over time. Your probably gonna go into this cvt over and over again. Either modding, maintenance or just preference. Anyway I would install what you feel like will last the longest down the road.

I have used heli coils for years with no problems while repairing all type of machinery. (Not my scooter though...yet) As long as you tap the hole correctly after drilling it to the correct size and break off the tang at the bottom of the hole to allow the coil to unwind in to the new threads you have cut, it should work just fine.
The kits used to come withe the right sized drill and the required tap and several coils. Most of the folks I have seen having trouble with them did not break off the tang once the coil was screwed into the new threads. Just read the instructions, it is not hard to do and it is a good skill to have just in case. It is a good option in my opinion.

Grrrr... I put 7 helicoils in and one of them when I tapped he hole, it didn't create the threads and it's just smooth surface. The helicoil doesn't sit tight... I don't know how this happened.
What do I do now?

How many of the original bolts are holding the cover on?

You most likely threaded it crocked!!! I have done it many times!!! You will need to go one size bigger helicoil and get a bolt to match it...... If it were me anyway

Okay so originally you said you had stripped 4 screws right? Now you say all but one is holding so I assume that you successfully installed 3 helicoils and the fourth one wont hold?
If that's true than forget about the last one. The cover isn't going to fly away with one missing.

Yea true it won't hurt niutin.... I tell ya though just by me changing my cvt cover to a bigger and much thicker One I could tell a huge diff in how the bike drives in general though..... Crazy how it changed the feel of it....the cvt cover is basically your swingarm support ..... So it is important to keep it bolted tight anyway......

One way have used on threads that did not require much torque on them like CVT covers was to use the putties like 'Kneed it' or metal set that come in a sausage shape. Squeeze/mix them together then form a snake and jam down into the hole. Wait for it to fully cure then re-tap.
I would certainly not use this method on say engine case bolts but for 1 bolt hole on a CVT cover it would be a cheaper approach than a heli-coil kit.
Just to clarify though, heli-coil is best and still a good investment for future modding.
