Default XR750

I've been watching and reading for a little while on the site now and have finally started my first scale project. I'm an engine development engineer and race engine builder so I'm not new to machining but this will be my first micro build. I started yesterday by getting together some parts and laying them up in CATIA to 1/4 scale. I'll try to keep the build updated as it progresses because those are the threads that have inspired me to do a build (such as stevehuckss396 v.

My build will be a 1/4 scale Harley-Davidson XR750 motorcycle engine. The XR750 is still the dominate engine in grand national dirt track racing and where my roots are so it was an obvious choice.

Regards.
-Jordan

Welcome to the forum Jordan.

Nice choice of engine.

All the best with your design and build!

I've got most of the cam cover setup in CATIA. I'd like to do the cases next so I can get started on machining to help break up the measurement time.

Sorry for no updates. I promise this isn't a lost project, the Masters degree takes up a lot of time once classes start back up. I'm finishing up the right case along with the cylinder heads. I'll have to get more images at a future date.

Attached are a few more pictures of my CATIA files. The left and right cases are pretty much buttoned up as well as both cylinders. I am working on the heads during lunch breaks and started the rocker boxes tonight. I plan to start the machining process as soon as I complete the drawings for the cases.

I've also attached a couple of pictures of one of our race bikes for those that haven't seen a Harley-Davidson XR-750.
