Since posting mine.  I have had alot of people PM me.  About their Swing arm stretch projects and experiences.  It would be GREAT to see your pics.  Before, During and After shots.  If it was DIY like mine, or you TRUSTED and PAID somebody else.  I am real interested to see how you guys approached it.  Heres what I did to add 4 inches.
BEFORE STRETCH
 
Before welding,got the tubing from speedymetals.com about $30 incl shipping. they have great selection I was able to get the same size and thickness tube as honda used.  best for wire welding.



The numbers are now meaningless, thats what I had after notching myself, not even close to right.  Machine shop touched em up and made them perfect.  All 3 corrected to be right.  If its not perfect...try again.  check and triple check measurements as your welding.  check for warping.  your ass will be riding on these welds.  My friend did the welding for me, I trust his welds.  I WOULD DIE ON MY WELDS.  He is educated has a certification...his welds have reason and purpose. 

After welding w new bushings ready for install.  Machine shop bored tube correctly for bushings.

Out with the old in with the new...Halfway through swap. 

End result.  Rides great, new bushings helped that.  New chain, longer shocks from DCC lowered it a bit but not much, modified a brake lever connector rod using longer one off 69 CL350 sprint.  Had it up to but never over 80 mph on good straight road.  Barely noticeable in cornering.  I dont take hard turns at high speed anyway.  Im a 44 year old dad.  pretty conservative rider.  I am delighted it actually worked and I didnt have to scrap it. 

My only advice...Dont try this, dont over estimate your own welding ability,  dont try to cut corners,  your friends may brag about their abilities,dont trust me,dont trust anyone...if you are crazy enough try something like this, and ANYTHING about the entire project is questionable or not ABSOLUTELY PERFECT.  Do the smart thing...Just scrap it.  Put the bike back together as it was.  It wouldnt be worth GETTING HURT.
Godspeed and LETS SEE YOUR PICS.

Rear Fender mount....

  A couple guys have contacted me about the rear fender on swing arm.
I have plans to improve it this winter.  Right now its kinda scabby.  I was ready to ride so I just threw it on there in about 30 minutes.  its held up real good though doesnt rub and haven't  touched it since install.


This is the original cb360t front fender.  I had ground the rivets off to remove the brace rod.
So, I had to dig brace out of the garage.  I couldnt believe I kept it.  I cant believe I found it.

My plan is to hide the brace rod behind the shocks for a cleaner appearance.  But to get it on the road this is what I did.

The brace rods are about an inch short of what I needed for tire clearance.  So I cut and drilled little tabs to add the height I needed (first scabby part,  I intend to re-do nicer this winter.


Next I cut front mount from piece of sheet metal.  and drilled and tapped swing arm sheet metal.  1/4-28 bolts.  I used fine thread cause the swing arm steel is pretty thin.  This bracket could also be nicer looking. 

Moved tail light from bracket behind seat to fender cause it left a big gaping hole.  So taillight fills 2 1/4" gap tween seat and fender. 



also all the electronics (rect, regulator, solenoid are hid under seat.)


so thats it. PM me if you have any more questions

Looks great, did you add some tubes or anything inside for added strength and stiffness?   Or did you just butt weld the tubes together?  Im sure there is a bunch of twisting pressure happens to the swing arm when cornering.  Is your rear tire nice and plumb, level and square?  With the frame and front tire.  Like before you started this.  DCC has good prices on longer shocks to bring it back up closer to level.

I made it stronger  buy adding a couple pieces of pipe and plug welding it and the welding the pieces together . It still needs a bit od tweeking but it will be fine . I'm not looking for bigger shocks , I'm looking into honda rebel shocks to bring the ass end down more.

Sasquach,  regarding putting shorter shocks on your machine.  Im thinking that by changing up the level at which the machine sits.  You are in essence inadvertantly changing the degree at which the forks are raked.  You might come into a situation of "quick steering"  which causes the front tire to be under balanced and causes a tendancey to yank the bars out of your hands during cornering, swerving and just hitting bumps in the road.  the same thing that happens when guys get up to and over a 5 degree rake to make a chopper.
Also it may get the shocks laying at too much of an angle and they wont funtion as intended.  They may just bend and break.
 So be careful doing that.  I would ride it "as is" before spending the cake on new shorter shocks and see how it steers in all conditions.  Then trial and error the thing from there.  I dont know this will happen...but just thinking its may be possible.  Also if you do want to rake the front end, there are shops out there "online" that do custom triple tree rakes.  they dont modifiy the frame they do in the tree itself.  This cost a fortune.  but it can be done.

You'll need to modify the mounts to make it fit.

Sporty shocks are eye to eye, and the 350 is eye to clevis.

That said, the swinger looks good man!

And if you dont end up using those shock, and 650 was interested in selling, Im looking for a set.

Thanks.
