Jim's 1980 SG Miss September

Holy cripe, Jim! :eek: Those brackets look so good, nobody's gonna believe you made them yourself! :shrug: They look too "factory"! :bow::bow2:
...And I'm glad to see you back on your feet again, wrenchin' on the bike! :thumbsup:
 
Beautiful Jim...again.
I am going to steal that pipe bracket idea from you instead of using bolts.
Thanks

Thanks Mr. B.
Yeah.... I think doin' it that way will be much more durable. Spreads the stress more evenly.
Btw... love your new avatar. :D
 
Goin' Commando.... :rolleyes:
I picked up the EMGO Commando pipes from Amazon a while back. Cheaper than Mikes and free shipping to boot. The quality of the pipes is about what I expected. Time will tell.... The hanger brackets that came with 'em are definitely sketchy.... not up to my standards anyway. Time to make some better ones. Used some wood and tape to hang the pipe about where I wanted it... and grabbed the cardboard.

On the frame, I picked up the exhaust stud as well as the rear peg stud. From there it tapers aft to the pipe mount, and forward to the exhaust manifold clamp. Transferred that to some plywood...

...and cut two of 'em out of a sheet of 10ga. mild steel. Tacked the two pieces together and ground the edges smooth....

Drilled the holes and used the 20T press to make the required bends...

Test fit, tweek... test fit, tweek... test fit....

Welded the rear peg bracket in place...

Paint, bake at 175 for two hrs. Used some 1/4" mild sheet to make the pipe brackets.

Drilled and tapped for 1/4-28 bolts....

One side down, one to go.

Beautifully done !
 
Yes, Mike's actually sells that part but it's easy enough to make your own .....

Kinda hard to tell from the pic, but there isn't much metal on the muffie bracket. The bracket I made to go inside it was ground down until it was a snug fit... which came out to about .59" wide. Mikes advertises theirs as 1/2" wide. If they are in fact only 1/2", there's very little metal to get a good grip on the muffie bracket. Not sure I'd trust it....

On mine, the sides of the attached bracket angle out slightly, they're not square like yours. I started out with a slightly wider piece of bar stock and ground both side down at the appropriate angle until the part was a slip fit into the muffler bracket. Basically, I made the part as wide as possible.

G'day Jim,

Are they AN8-(whatever bolts)??

I shot this video of the Commando's not long after I installed 'em. Just been too lazy (and forgetful) to upload it.
I think they have a nice tone to 'em. A little quiet for my taste, but I'm gonna wait for spring and put some miles on it before I decide whether or not to drill a hole in the back baffle as some have done.

 
Thanks Bob. Yeah... 'bout that gauge... notice it was readin' 11.9v at idle? I just re-watched the video. That's odd cause I'm pretty sure it was about 13v every other time I've run it. I'll put my meter on the battery tomorrow and see what's up.
I've got about 15-20 heat cycles on it now (yeah... just 'cause I can. :whistle:), so I think tomorrow I'll re-torque the head and put the upper Mount on.
 
Thanks Jeff. Yeah.... that's prolly what I'll end up doin'.
