Well, here we go again... While restoring my 1972 Honda SL70 http://community.ratsun.net/topic/68899-1972-honda-sl70-restoration/I amassed a lot of extra "parts bikes"; now, its time to give one of those castoff bikes a new shot at life! 

 

This one in particular is a 1974 Honda XL70, the successor of the more valuable SL70. I chose to build this one because it had the cleanest frame and had excellent front forks, which is rare among these bikes.

So here it is, just your typical old trail bike, rough, missing stuff, but good bones underneath. You'll see what I'm talking about...

 

It was quite the mess getting it torn down, but after doing a couple of these bikes, you start to get an idea how to best tackle it. In my case, top to bottom and then front to back.

Now, I've decided that I'm going to build a Bobber style XL70 for use at swap meets, and also something to just have around the shop for goofing off on in the downtime. So if you're a Honda purist, look away!
 

Getting an idea of the new stance:

Marking spots for my cuts:

Looks much different now!

Media-blasted the frame, and starting the mock-up process:

I've decided to use the original swing-arm as the lower frame rail, since this will allow me to keep the same wheelbase, and also let me use the factory chain. 

 

Here's the new frame tubes getting cut and notched to fit:

All welded up!

For the lower frame rails, which you can see in the previous post were just cut short, I elected to simply loop them in and close off the engine area. The rear is plenty strong, and since I'm a paltry 135lbs, no need to overbuild it...

So here's where I sit at the end of today:

I have a 125cc Lifan motor ready to bolt it, so that will probably be one of the next things to do. But first, I need to shave the frame, removing all the original Honda mounting points for ignition, coil, air filter, foot pegs, etc... Since the Lifan is  CDI ignition, I won't need switches, a battery, or any complex mounts. 

Since this will be mostly for cruising around in the day light, I have no plans of installing an operation headlight or tail-light, I might install some dummies, but it's more a design study than my personal bike. 

 

Stay tuned for more thrashing, I'll be working on this steadily as the parts arrive. It's gonna be a bit of a cross between a dirt-bike, hillclimber, and a bobber; so there should be something for everyone!
