Boring post

Standard

Final adjustment to the flywheels to resolve a slight taper on the bore. The milling machine isn’t the first choice for this kind of work, but is giving good results. Setting it up was a bit of a faff though.

Measuring the distance between centres, we’re slightly over the planned 3.25" stroke at 3.3". It won’t matter but it does increase the capacity by an extra 46cc. The final capacity will be 2796cc instead of 2750cc.

I hope that doesn’t affect the insurance!!

About Sophie Whiptank - aka Bart

I'm just a bloke doing some stuff, the more interesting bits I post on my blog. Scroll down far enough and you'll see me riding from Melbourne Australia to Birmingham, England in 2014. But now I'm working on another project, a single cylinder motorbike engine at 2750cc!
