Hello, I wonder if anyone knows the differences between the TZ350F&G regarding the _frame_. I´ve checked TZ350.com and can only find out that the F was known for developingcracks in the _frame_ (headstock area & rear engine mounts) My _frame_ (F) has heavily repaired engine mounts and reinforced headstock (4 tri-angular bits welded on as support) Have seen a _frame_ (G?) where the two tubes at the front of the _frame_ (below headstock) has an extra "skin" / "tube-half" (tube cut lengthwise) welded on. Could that be from factory on the G-model? Jens
