Welcome to the forum. We're glad you've joined us here and that you're asking for advice before making a big mistake.

Do not use any rubber or resilient material between the engine and the bike frame. This is a subject that has been discussed here many times. You want the engine mounted solidly to the frame. Rubber, or any soft material will NOT eliminate or reduce vibrations but in fact will amplify them.

Yes, motorcycles and cars use rubber mounts but the type of mount is not the same as most builders try with a motorized bicycle engine. They incorporate a rubber sandwich that is a different concept that putting rubber in the mounts of your bike engine.

Rubber in the mounts will only transfer the vibrations to the mount fasteners, which will eventually fail because they are taking all the stress. Mount the engine as it was designed to be mounted and forget any rubber in your mounts.

As for "custom tanks" many of us use motorcycle fuel tanks that have been adapted, modified, to work on a bike frame. What specifically are you looking at as far as a "custom tank"?

Good luck and keep us informed on your progress.

Howdy and welcome to the forum.

It is not a good idea to use rubber for mounting the engine. Using rubber will actually increase the vibrations. The rubber will allow the engine to vibrate rather than insulate. It's best to mount the engine directly onto your frame. This will help absorb the vibration and dissipate them.

I don't know if somebody on the forum is doing custom tanks.

Also google "Ghetto Bikes" and "James Salsero" for another source of outstanding custom and in-frame tanks to order.

Been away for a little while. Who has the mount kits for 4 stroke motors for Point Beach bikes. Picked up another one @ a garage sale & have a Honda GTX 50 sitting around doing nothing. Never been started. I still have my 66cc on my first Point Beach, 3rd motor so far. Thanks for any help in advance.
