The bike is nearly done, and I have issues with the flanders dog bones risers on the custom springer. It has 4 pivot points, and even though the pinch bolts are SEVERELY torque'd down, it still moves and pivots on those axis when going over bump/pothole or when kick starting. I kick started it tonight and the bars were 5 degrees twisted. I'll bet if I wrenched the bars I could get them 30 degrees pivot in either direction. Not good!!!
So, it's operating kind of like a differential (at least, that's how my brain sees it). A force on the bars causes the dog bones to flex and one bone move forward and the other back, so the handlebars are no longer parallel with the top tree. It doesn't help that the ears on the top tree and the handlebars are slick, neither is knurled.
I'm scratching my head on this. The only thing I can think of is to [1] knurl the ears and handlebars, carefully, with application of channel locks or pipe wrench to dimple and knurl the chromed surface (but, that means future rusting), or [2] carefully drill and tap holes on top and bottom of each dog bone, and install set screws. However, that means that the bars really can't adjust.
Pulling my hair out on this, any ideas? Has anyone run into this? Picture below...
