    Stiffening the mount would not be good, you would then transfer most of the vibrations through the mount into the frame.

    Hmmmmm nice bit of porn there!

    I hope you are able to ship these bad boys to the UK for us poor forgotten about chaps?

    Looking good guys.

    Stiffening the mount is exactly what Tpehak's project will do. The original mount has the central core bonded to the rubber vibration isolation compound in only a few places. This creates a certain amount of free space to allow the central core to float in lateral and axial directions to minimize vibrations. Tpehak's project will increase the stiffness by increasing the amount of rubber in contact with the central core. This will in turn reduce the amount of movement and therefore increase vibration transfer to the frame.

    With any rubber mount on any frame with any engine there comes a point where you have to sacrifice comfort if you want extra performance.

    I am looking forward to find out how Tpehak's project performs :-)

    I have no tools to produce the parts, I hope someone will produce and sell the parts and it might be profitable for them if this will work properly. I ordered these parts from China and expect them to be in my hands next Monday.

    hopefully just a rough ride right?
    Failure can cause death or serious injury because of the engine can fall down while riding process. If the aluminum Chinese guys used for the prototype has the same property as the original bracket material it should be OK. At least I asked them to use 6061 aluminum alloy. I have no idea if they followed my restrictions.

    The idea is that the bracket and the rubber inserts have specific configuration. Initially I am going to use for the front and the back tubes very soft 30-40 shore A hardness rubber for less restricted back and forth vibration. The left and the right side tubes are 50-60 shore A for more restricted left-right vibration and up-down vibration and providing vertical support. The original front isolator works the same way, it has vertical through holes in front and behind the bushing in the rubber, so the bushing has less restriction back-forth, and solid rubber restriction left-right and up-down. I ordered different rubber tubes with different hardness to test different configurations to achieve similar behavior. I am going to attach force gauge to the original isolator bushing and measure deformations to calculate stiffness in different directions and then I am going to adjust the rubber tubes configuration to have similar stiffness in the same directions.

    If you want to be sure the parts are made of 6065 heat treated aluminum you can get it tested. The scrap yard around here tried to screw me on a load of the same aluminum.I told them what it was and The guy pulled out a devise that looked like a volt meter. Said, yup. You can have it tested.
    I want one by the way.
