1982 XR100 80s Action Thriller

I came home from Barber with a 1982 Honda XR100 a swap space partner brought to sell. The tank is dent free and clean, with a nearly perfect patina. I pieced together the engine from several donor anchors I have in the barn, pluse the 100 engine that came with the XL80 in the pic. I'm running a 120cc big bore with a Mikuni VM26. It took a little massaging on the carb boots get the Mikuni to fit, but pretty easy fair.

The little dude rips.

I only have one stock side number plate, and no one makes the 82 plastic, so I'm piecing it all together with Maier XR80 number plates, rear a Maier rear fender, DC Plastics front number plate and restored front fender. I lucked out with nearly perfect chrome on the rims, no rust on the spokes and a brake pad replacement.

I'm waiting on delivery for the front number plate and still need to install the skid plate. Vintage Redwing shocks do a decent job for this little bike, but I am searching for something better. The shocks I carried it home with were way too long.

I'm pretty convince XR engines get abused worse than lawnmowers. It always takes a really good cleaning and picking for parts to get good engines together. The plentiful Chinese big bore kits make it easier. The clutch was like winding up a spring when you dropped the kickstart lever because all the discs were glued together.

A VM26 is pretty darn good on this engine. It was pretty easy to tune. In order to run the stock air box, I drew up another tube in Fusion and printed it in TPU. This is the second one I've done, with the first having finished it's first season on an Elsinore. Ultimately, I redrew what you see here to get it much closer to the air box and printed again.

Finished off the exhaust by cutting off the stock muffler and weldinig in an old Supertrapp.

My favorite year XR100.
 
how has the TPU been holding up to gasoline? i bought some filament to play around with.

Most TPU is fuel resistant. I've read examples of people using it to print carburetor gaskets, but I haven't tried that myself. Both of my attempts so far have been on the airbox side with zero degradation or swelling on the Elsinore so far.
