I purchased this '74 350F recently and realized the petcock likes to rub the carburetor. I've seen posts in the archives about different years of bikes having tanks fit slightly different. Any suggestions for a fix? Both front and rear rubber mount seem decent. Frame looks straight. I've just been using cardboard as a shim to try and keep it separated. Here's a few pictures..... Yes, it was originally blue. PO painted it red. Looks pretty good and I look at it multiple times a day.
