I have a gas gas txt 300 raga 2007, the front chain slider/rubber is worn and the chain is rubbing on the swingarm. It appears to be riveted on and it looks like the swingarm needs to come off to change it. Is this right? It seems overly complicated for changing a piece of rubber. Thanks

Yes the swing arm needs to come off to change the rubber "swing arm protector chain rub thingy"

I have looked at my 2003 Gas Gas and them rivets look huge, If I ever need to change mine I may try threading the holes for the rivets and switching over to screws.
