The last few days were quite productive and got a few things checked off the "To Do" list.

First of all, was the installation of the Jadus tank leveling kit.  This was a very straight forward process and the decal templates to locate the new holes worked great.  After installation the lines of the underside of the tank match the top rails of the frame perfectly.  I think it makes a huge difference with the overall look. 

Stock position tank mounts



Carefully drill out spot welds



Pop off stock tank mounts



After the stock mounts are removed



Apply supplied templates to locate new holes



Drill hole and install new mount with supplied hardware



Install tank in new position with riser plate

Yesterday I was able to "convince" my buddy with 2 flats of beer to hang out in his shop and throw some sparks for a while.  We  removed the remaining tabs, welded in the rear hoop and removed the passenger pegs.  The hoop took some finessing to get it to marry up to the frame and make the gussets look right but eventually got it done and looking pretty good. 

The first few pics were posted previously but I wanted to repost to show the gussets, and the hoop before the installation.







A little bit of prep work with the knotted wire wheel to remove scale, paint etc.  The flats of beer actually served a second purpose to hold the frame up for some of the work!





After some cutting, blending and manipulating the gusset we ended up with this:







Here is a picture of the final product also showing the new welds on the cross brace where the seat mounts were cut from.  A bit of sanding and black paint should make this look much nicer!

While we were in the groove, I wanted to remove the passenger pegs.  The issue with these bikes is the passenger peg mounts support the side stand on the left side and hold the brake return spring on the right side.  In order to retain the functionality we made a couple small gussets and then capped the end of the remaining tube by welding in a carriage bolt on each side.  I could have made the left side much smaller, but the idea was to keep the symmetry.

I do too!  Thanks.

I plan to make the seat to match the contour of the frame rails and mate up with the front of the tank so I *HOPE* that it will look good when I'm done.

I like the look of that hoop and how its welded to the shock mounts did you use plugs?

Maybe some speed holes in the gussets for the kickstand/brake lever? Its looking good.

Thanks man.  We didn't use plugs ... just a butt joint and then utilized the gusset for additional strength.

I didn't think of putting in speed holes, but like the idea!  The flat bar is rather boring and that detail might spice it up a bit.  Thanks for the tip!

Nice welds!  Great idea the way you cut the rear frame rails out to leave the gussets there.  That'll be as strong as anything!  Great documentation too  ;D Cheers
