Acerbis still makes all those plastics, so I can get new ones cheap. It'll be fresh and new!
Great Decision. This needs to be that dirt / ADV bike again.

Let's face it, you'd need serious frame mods and reinforcing for it to be a big dirt bike ... but keeping it this way it will become a really comfortable trail / forest service road / ADV bike ... And if you want to make a scrambler ... you can find one less mod'ed in order to make the transformation.

And besides ... this one looks SO GOOD

Lovin the rebuild.

Well, it will be functionally that bike, but altered a little to fit my needs. eg, it's not set up to carry gear for a trip. I need to fix that. The geometry is not right for long road miles, and I need to fix that, too.

What I'm NOT doing is chasing a style...I'm chasing functionality first. But I am using the aluminum fenders. That's my main vanity feature -- I just like that look and I think it's right for an old boxer.

I picked up some tubing yesterday and will start working on a new subframe -- I'm building the correct rear rack and side bag standoffs right into the subframe so it's all one piece.

I'm sending off the wheel hubs and a few other bits to be blasted clean so I can get the new wheels built up while I work out the subframe, seat mount and tank mount. I really want this thing on the road by spring. Going to be a big snow year and I want to go see the Yosemite waterfalls.

More mockup to make sure the plan will work.

Nice. Like the overall look.

This is what it was all about with mine. Oh, wait, IS all about, 'cause it's not done.

It's got to work everywhere that I want it to--any surface, commute, tour, etc.

Make it your own, man.

have you checked to make sure you have clearance between the front engine cover and the front wheel at full compression of the suspension? sliding the forks up that far might cause interference. it's hard to tell from the picture.

Yup...plenty of clearance. Room for the fender, too.

Starting on the subframe/rack. I got the wrong tubing for the main subframe (3/4", but too thin-walled) so I started on the top rack. Got it flat and square on the first try! 12" square...will have three crossbars. Wide enough to mount my Pelican case hardware bits, or a big Motofizz bag. Side standoffs next...

I got a heavier gauge of 3/4 tubing for the top rail of the subframe. The existing subframe was relatively light gauge since the bike was probably not used for fully loaded touring. I want to be able to have a single strut (on each side) holding up the subframe, with the top rail cantilevered out past the seat and strong enough to hold ~70-80 pounds of gear on rough roads. So I cut off the old subframe, preserving the nice mounts for the shock, and welded in my heavier gauge tubing. I notched the bottom of the tubing on both sides of the butt joint and inserted a piece of 1/2" tubing that was notched and bent till it spring-fit. Welded over that notch on my highest voltage, and then welded the butt joint. This should now be overbuilt by an order of magnitude.




Next up is to finalize the angle of these rails and bend the part that extends past the seat so they are level to the ground. Then make the support rail that bolts to the old footpeg bracket. All the rest of the tubing can be lighter gauge.

BTW -- I weighed the pieces of tubing. The difference between making the subframe "as strong as all the other ones" and "overbuilt crazy strong" is only 1.7 lbs. Small price to pay for peace of mind.
