    Most engine vendors sell engine mounts for oversized engine frame tubes. Please give us a chance to help you with this before you
    resort to drilling a hole in your frame. There really is no good reason to drill the frame anymore to mount an engine.

    Which 4 stroke mount is in the EZ motorbike kit now?

    There are no pics of what you get so it would be great if you posted a pic of all the parts in an EZ kit.
    A pic of your bike would help too.

    already, i can see issues.

    say goodbye to the cranks and chainrings on your frame. you need "offset" cranks to clear the engine.

    imho, that makes for an awkward ride.

    the gearbox in the kit, is, i believe, a decent choice, nicely made... i see a supported sprocket. thats good. but possibly not.

    the mount, well...if all you need to do is drill the bolt holes, and replace the existing clamp straps with something wider....easy peasy :) go for it!

    the inclined to say they really are POS.... but thats only from experience, mind you.
