Rustin Olson sends in this nice rider.
I built this myself in my garage. Took sometime but I’m very pleased with the out come of my first build. If so I can send high res pictures.
Thanks

Beautiful, but the more I look at it the more I think about having my head bashed against the tops of the forks.
Right? The bike doesn’t look lowered either. It must have some extended chopper forks on it.
They are clamp on bars, and he moved the headlight bucket down. I think the forks are standard.
