Did you check your rollers to be sure they are okay? Maybe a video or audio file of the noise will help.

I didnt check the rollers but can they make any sound?, is sounds like a bad bearing and so far I am hearing it only at idle without wheel spinning, it sounds like quiet metalic ticking

They wear and can start to rattle.

Is there any way to eliminate crankcase bearing?

Find out problem, it was variator 3 plastic parts which prevent metal to metal contact worn out

Stethoscopes are cool diagnostic tools. The closer it is to the problem the louder it is. Find a bad car pulley bearing in a heartbeat. But you can't listen to both at the same time.

Glad you found it. If it was a bearing the place to start checking is pull the CVT and see if there is any movement in the crank shaft. If none there pull the cooling shroud and check the flywheel for play. I had a bad bearing on a TGB and the flywheel had lots of play.

Well hopefully it didn’t trash your variator, because it will over time. When my scoot was my main ride, I always tried to have a spare set of the “v” guides on hand. It’s better than paying $30-40 for a new complete variator.
The more wear the 3 posts have that the guides ride on, the faster the “v” guides will wear out.

I agree that's why i have another entire engine just for parts got it very cheap😉 |

Instead of a stethoscope, a length of vacuum tubing works just as well in most cases. Gently hold one next to a functioning ear, and move the other end around the suspected noise making area. The tubing will block most ambient noises if held close enough, and will transmit noise without interference to the ear drum. It works pretty well, and is portable if you roll it up and stuff it in your pocket.

You can use a long screw driver like a stehiscope. Just touch it to the engine and put the handle side on your ear. Works, but not as well
