When I say I tried everything, I mean I loosened all (4) the mounts, wiggled the engine/trans, used a scissor lift under the engine, a pry bar, some thoughts and prayers, nothing would center it.
Being the obsessive type, I also went as far as getting an adjustable top engine mount. Only then was I able to closely center it and then 15K miles later the rear tire had irregular wear on the one side.
Took it off and went back to stock and it's been fine that way for 40K miles.

Anyway, just sharing my experience. Good luck to your Sir.
thank you for sharing I’ve been chasing a vibration since last riding season front and rear wheel bearings have been replaced front rotors rear tire both tires re-balanced different belt tensions and no change. I saw the broken cog when I was adjusting belt the last time so I got a belt dark horse comp and Hayden tensioner to install.

That's the high elevation position. Harley only provides those for people who do wheelies.

Alloy Art makes an adjustable rear upper link to keep the engine centered at the back end and tightens up the frame also.

If you've made a decision for replacing the mounts. Ive been happy with the switch to polyurethane mounts on my bagger build.

Well you explained why things are hitting. You want to abuse it better find either solid or poly mounts, rubber is just going to keep deforming and banging hard parts .

Does not mean a thing. You already know you are abusing the machine so there is no easy out on this.

You have 2 choices , first is you know you got a heavy hand and like getting frisky so set the machine up accordingly and enjoy it with peace of mind.

Second choice is deflect on the why like you just did with the buddies comment, look for an easy out and continue to have issues till something you can't ignore breaks.

I got long priors breaking **** from playing hard with my own toys, I pass on this hard learned and sometimes expensive knowledge in hopes others maybe don't do the same things.

I do mean all this in a helpful way, I'm an old bike wrench been there done this more times than I can remember with others.

Got the polys , there is not enough vibration difference to worry about, like you'd really notice running it out all the time.

You may be good on the M8 with a balancer. Im a S&S 124 TC. Definitely more vibes at a standstill. Moving no big deal. Its a tradeoff for better handling I was ok with.

I hear ya ben a gear head sense I was a teenager in my younger years I blew up everything I owned I got good at replacing or rebuilding all driveline components. I know it will come with a certain amount of expense to get bike right. I have not ben able to locate poly mounts only thing I found was glide pro mounts most of reviews people went back to stock they didn’t last.
