Anybody ever had this happen with an oversized tank on their yz 2 stroke?
It happened in only 20 hours of riding and it dug into the frame pretty good. Is this gonna affect the integrity of the frame?

I'd be more worried about the fuel tank getting rubbed through.

The tank has a little wear, but it seems like the tank did more damage to the frame than the frame did to the tank which is odd being as aluminum is harder than plastic

I had two tanks get worn through from a steal frame in a pretty short amount of time. I put down a layer of the soft side of 3m stick on Velcro on the frame and it has been good ever since

Aluminum (100mph) tape helps prevent frame wear.

Aviator, fix everything with 100 mph tape

I appreciate the replies guys, thank you. Now, any opinions about what to do with the gouge in the frame? I was thinking just build it back up with JB weld and cover it with tape so this doesn’t happen again. Hopefully it didn’t cause the frame to become weaker

If I recall correctly this would happen with my stock tanks on YZ’s. Never did anything about it, never had an issue

At that point, it would not be a strength issue.

It's on a corner of a relatively solid section, and has plenty of distance from the edge of the 'pocket', on the backbone to swingarm pivot member. I'd still put a little patch of protection ( Aluminium "100MPH" tape, Contact, even electrical tape) at that point.

It's just another example of how plastic and rubber nearly always, well Always defeats aluminium, and, indeed, steel.

I've seen radiator shrouds be allowed to go all the way through a main beam on a fair few aluminium frames. And all it would have taken was application of some clear contact at touch points, and the replacement of it a regular intervals.
