Look at 11 o'clock at you outer clutch hub as i looks like a crack to rivet? In your pics i cant see the rub point you refer to. Also is the outer cover vented as they use to get heat and break belts due to expansion. I ran a 3" and the belt tightened a bit due to alloy pulley on crank

You may remove some material at rub point. Also fit a new motor sprocket seal with spring facing in. Probably the same with trans and clutch pushrod seal in nut if in there.

Dont think the outer primary bolt goes in that deep? To need helicoil. You can buy vented inspection & derby covers.

I've run a jillion miles with no covers. Stones have never been an issue.

Every single belt I've run with a tensioner has failed spectacularly.

Anec-data.

Done 10 plus years with 3" just got to pic stone out regular as the pit the pulleys
