If the engine is tight in its mounts, it sounds like something is wrong inside the engine.
Pull the ignition cover and see if you have up and down movement in the crank bearings. Double check your flywheel and flywheel weight.
I had one Steahly FWW that did not play nice with one specific flywheel but the FWW worked fine on another bike. The one flywheel was machined incorrectly with the hole off center from the puller threads, but the flywheel was balance corrected for it so it did not vibrate without the flywheel weight.
