    Almost everyone has . Teixeira Tech offers a really good Gusset that should be a huge help .

    i broke the back bottom mount and even bent the front triangle bolt on mounts. I just doubled up the triangle mounts on both sides and it fixed that problem pretty easily..

    I was told it's a Yamaha manufacturing defect on all pre 2010 models, there is a run of weld missing off the left hand engine mount which weakens it and will almost certainly break when raced. If left unoticed it will eventually cause the other mounts to bend and break. I've also heard of some getting replacement frames under warranty from Yamaha. We've just had ours brazed.

    Yea like Bobby said, the back ones will break for sure and it helps if you double up the front triangles. Last year I just doubled them, this year I am having thicker Titanium ones made.

    we doubled our triangles up and re-welded our frame and made our own gusets for them and have had no problems since.
