The Chopper Compendium

So as I said the triple gave me such a headache I decided to cut my losses & sell the engine (after much thought)...Enter a 62 Norton Atlas 750......This engine didnt fit in the frame so I cut the down tubes out...

I the bottom rails were also wbay to wide. I could have used spacers,but wanted a cleaner look. I made up new bottom rails that were only as wide as the motor mounts.Bent some new down tubes

Once that was done, I figured I might as well change the seat post & made gussets for the neck

This is where Im at now. I plan to increase ground clearance ,so a redesign of the rear is going on now.

looks cool glad you stayed brit I love those old brit bikes

What's it gonna take to get this engine running? It looks a little hollow.
Inquiring minds want to know.

It’s a lot easier to put it in & out of the frame empty. The engine has been under my bench for about 10 years, thought it best to see what the insides looked like. All looks good, haven’t measured anything yet. Hopefully it will be a piston & bearing type thing.

some more work on the frame. Now to make the axle plates. The last pic show the shape of & hopefully how the rear wheel will pivot giving me a little rear suspension. Ill be mounting shocks on the seat rails.

I got the plates made up & tacked on. Mocked up the wheel to see how it looked. Not sure if I will use shocks like this or go with a regular type shock. Last pic shows the deflection from vertical. 1" at 6" of total travel, but really not looking for much. Just enough to soften the ride a little.

Its been a while since Ive updated this. I made the swing arms from aluminum. Bought a chunk of nylon to make 1/16 thrust washers from. I milled a little under that from the arms. Also installed oil-lite bushings for the axle & shocks.

Made up a seat pan, mounted the battery box, & oil filter. The brake stay is on & got rid of the speedometer gear (will be using a speedo app on my phone to keep the bars clean as possible.

I didnt realize thered be so much slack in the chain. I made this tensioner out of delrin.

Have you ever made something, stepped back & said...yeaahh...I like that? Well thats exactlly what I did when I finalized on the seat mount. Right after that I went to put the oil tank back in & it didnt fit....WTF...I didnt want to change it cause like I said I really liked it. So I cut a piece out of the middle of the tank & welded it back together.....all good

Made up the rear motor mount & made a set of 1" bars running a 7/8 throttle
