There have probably been threads about the ProMod Adjustable Motor Mount and the PMR Clutch Cover before, but I'd like to add a little mini review of my own.
Both of these products are available individually or together in a kit with a clutch, along with other mini bike modification products, like jackshafts, etc. from HotRodMiniBikes.com
I'll get the only negative out of the way first. The rest is all positive!
In my opinion, the website content could use some improvement. The pictures are not very large and the descriptions are not as thorough as they could be. For example, few dimensions are given. OK, the negatives are done.
On the positives, let me first comment on the company itself. We all find companies here and there that have very good customer service. It is rare that I find companies which I would consider with truly OUTSTANDING customer service. In my mind, I have found only a handful. This is one of them. Rest assured that Brad will take care of you if there is any issue.
Add to that, they ship Priority Mail so Saturdays are ok for delivery and a box coming all the way from WA state to me in NC gets there in the normal 3-day priority mail time. And Brad ships immediately, none of this sitting on an order for an extra day or two.
Let's talk about the two products in the title.
I recently changed out the old 2.5hp clone engine in my Sensation MB-6A for the Predator 212. (What an incredible difference, but that's going in another thread.) I could see from the existing engine mounting (using steel C-brackets), and from the far-right offset of the engine plate on the frame, that I was going to have a devil of a time, aligning the new engine clutch sprocket with the rear sprocket. And tightening the chain would probably mess that up every time.
I did some searching and came upon this adjustable motor mount plate.
This plate is the cat's meow (or "epic" or "random" as my kids would say). Since the website description says this is for a Doodlebug, I was at first concerned that it might not fit on the Sensation, but TomH gave me the dimensions in this thread and I could see it was going to fit fine.
The plate comes with everything you need to install it (8 square-head bolts, 8 locking nuts), besides a little bit of brain. The square head bolts fit in the recessed channels on the plate so you only need to turn the nut. The bolt is held in place. I started by following the instructions for the DB30 (included) and immediately saw a little problem:

One set of the slots in the plate was smack on top of one of the frame tubes. The Sensation frame tubes are much closer together than on the Doodlebug.
Fortunately, that had an easy solution: turn it around 180 degrees (and I have to give some of the "brain" part of that to my wife-ha!):

I wish I had taken measurements of the slots. I thought I did, but can't find them, and I'm not going to remove the engine now. But I have a few pictures of the installed plate:

On the Sensation MB-6A frame, there is no need to drill new holes in the fram plate. The ProMod plate's slots are already the correct distance apart.
The instructions for the DB30 say to remove the fuel tank and air filter box before attempting to install the engine over the bolts on the mount. Well, the Sensation frame has enough clearance for the 212 Predator engine that that was not necessary. I did need a second pair of hands to help get the bolts to go through the holes on the bottom of the engine while I was holding the heavy engine, but one of my boys did that in about 20 seconds.
So now, the engine is in place. One set of four bolts gets used to move the engine right/left to align the clutch. The other set of bolts gets used to adjust the chain tension. This contraption makes a really nasty job (engine alignment) just a dream. Absolutely worth the price.
I'm going to upload this before some computer gremlin makes off with it. Will continue next post.
