Fan clearance

The blades of the fan will move forward as rpm increases.
If it were the clutch that close, - maybe.
The blades usually suck forward, - one of them may hit the top or bottom tank, - bend, - then wipe out the rad.
My son's is about 1/4 clearance to the clutch hub, and the rear mount is captured, so forward movement is limited . He's a spirited driver , no drama .
