Thanks Warlock!
I found the manual download, will be reading it all later when NOT at work... well.. read some already...
Following the progress of my parts coming in. I am SO much more comfortable planning and working on the trike with the vibration problem solved. I was having night sweats thinking about putting on the new driveshaft... and still having the issue persist.
On Tuesday I ordered running board covers from Sweden. They are in Germany now, and slated to arrive by UPS Monday.
On Tuesday I also stopped by the Honda dealer, and ordered my motortrike and Honda parts. I was told all were in stock, YAAAY! and will be here next Wednesday. Two days after the parts come from Sweden. M'ok!
And now that Mrs V has experienced the ride as it SHOULD be on the trike, got the 'OK' to get the rake kit.
