That does look good with the new seat, stance, and tank reposition. Do the covers strap onto the frame tubes? Back-side pics?

Thanks guys.  Yeah I took some photos of that, forgot to share - see below.  The rear of the covers is far less attractive than the front.  I used filler to make somewhat of a mould and pressed it onto the magnets I had on the frame while it was still soft.  I covered the magnets and brackets in grease so the filler wouldn't stick.  Then I cleaned up the filler (dremelled it back to a smooth clump) and glued and screwed the neodymium magnets in place.  On the frame are just standard 7/8" and 1" tube/pipe brackets (that I will eventually paint black) with a large countersunk screw head - these are what the magnets pull on to.  They seem to hold in place really well, but we'll see if they stay there when riding.  If not, i'll try fixing them from the rear in another way.

Here's how the backside ended up after sanding and painting.

Ok - so the silver straps on the frame tubes (above pics) hold the neodymium magnets in place.

Yeah almost.  The magnets are actually inset in the filler on the inside of the covers - held in place with a screw and glue (they were magnets with a countersink on one side).  Then the frame just has some bolt heads.  If I need a stronger clamp later, I could add magnets to those braces as well - bolted on.

Got a nice ride in today on the test mule.  Spring is definitely in the air, although air temps have not made it to 10 yet!

Things have been getting a little OCD here at the end - decided I didn't like the ugly goldish plated screws of the new non-vacuum petcock I decided to go with.  So I trimmed up some stainless ones.  Much better  :D

Looks better. Not full OCD, there is still a cast mark on the petcock switch.
I'm not sure, but don't ask Brodie.

Way to many build and half done projects to list here.

Haha, I agree, that mark on the petcock plate really bothers me!  Gotta draw the line somewhere I guess.

No all mounted - along with the harmonic intake and foam filter - with Jadus logo  :o ;D
