Before Jin produced this Knucklehead V-Twin, I had not ever seen an affordable working scale model of it.

I had seen and photographed Jerry Kiefer's 1/8 scale Knucklehead engine at the NAMES show in 2011. I was absolutely astounded by his creation. He measured and scaled down every last part of his near mint original 1947 Harley Davidson Knucklehead motorcycle.

It has proven to be quite reliable and starts by hand on demand. I have now started it about 30 times.

Here is a video review (is it a vlog?) with some shameless promotion included for Stirlingkit.

Enjoy,
