Belt problem critique please

[Yamarus]

I disassembled the primary clutch. The spring was rubbing the clutch. I turned the spring over, I'll see what happens. The mileage is 3,700 km.
Tomorrow I will measure the offset.

Springs are always going to rub, vibrate and wear the paint off. Its not the spring rubbing that caused the belt to break.

I measured the displacement. There were no adjusting washers from the factory. There was a locking ring, I didn't take it off. I removed the 2mm from the rear clutch, but did not remove it from the float. When I put the clutch on, I had a gap of 2 mm, the clutch was floating. In the near future, I will take 2 mm off the float and try again.

The displacement with the washer (as it was from the factory) was ~ 61 mm. After killing 2 mm from the rear clutch, the offset is ~59 mm.

Don't take too much off. Whatever is removed from the back should also be removed on the spacer that slides over the retaining bolt.
2.5mm total is about the max.

I removed 2 mm from the float (it was 4.25 mm, it became 4.05 mm). Do I need to install a standard spring and gears? Or replace only the EPI PURPLE spring with a standard one? Or to see how this assembly will work with the new offset?

I don't understand your math there.
Removing float requires adding shims around the outer spacer.

The secondary clutch plane has been removed by 2 mm.

The offset is now ~59 mm.

If you want no float you must add machinery washers around that spacer pictured. You'd have to measure to come up with what's needed.

I left the locking ring. I installed a clutch, an aluminum sleeve and one 1 mm washer. The belt is flush with the clutch. The offset shows ~ 59 mm.
The clutch has no backlash.
Am I doing something wrong?

You have to measure the difference between where I marked one and two(also add on the width of that washer) and add machinery washers if you want zero float.

Removing float from secondary

This is how mine is set up. First I set my offset with the hurricane offset tool. Second I cut the aluminum plug to be flush with the clutch hub. This is my clutch bolt. The washer next to the aluminum plug holds my clutch from floating. The two small washers are used to set my belt deflection...
