The Bride is a roller

The front end got wheel spacers and new tire this morning, so I mocked it up for a preliminary geometry assessment and then rolled it outside. 34″ seat height and 48.5″ wheelbase. … The Bride is a rollerRead more

Rear wheel mounted

April 29, 2021January 1, 2025

After measuring a bunch of times, I conjured up the gumption to cut into the swingarm. I went slow, with a hack saw, and actually managed to make a perpendicular cut. I … Rear wheel mountedRead more

More lathe work

April 26, 2021January 1, 2025

I chucked up the sprocket carrier again and moved the sprocket face about 6mm inboard, to bring the rear sprocket in line with the idler sprocket. Now I need to modify the … More lathe workRead more

Idler sprocket

April 22, 2021January 1, 2025

I gave up on installing a true jackshaft in favor of a single idler sprocket. There simply isn’t room for it without extensively modifying (almost completely re-engineering) the swingarm pivot. Beyond that, … Idler sprocketRead more

Rear sprocket modification

April 20, 2021January 1, 2025

Speedometer mock-up

April 9, 2021January 1, 2025

I bought a speedometer from a Suzuki GZ250 and set it on Bultakenstein to see how it looks. It’s a bit on the large side, but the angle and placement are nice. … Speedometer mock-upRead more

More jackshaft design work

April 7, 2021January 1, 2025

Instead of an actual jackshaft, someone suggested I mount a single, freewheeling sprocket on the swingarm pivot. That’s an excellent suggestion, and definitely worth considering. For right now, however, I’m going ahead … More jackshaft design workRead more

Progress photos

April 6, 2021January 1, 2025

I rolled Bultakenstein outside for some progress shots, to keep me motivated. Chassis fabrication is basically complete; now it’s on to engine work, intake, and exhaust. There have been a lot of … Progress photosRead more

Revised steering complete

March 26, 2021January 1, 2025
