DT1 flat track project

I got a start on the chassis assembly. I got some new shock bolts and a fender mount kit from ebay seller motodad24. He has some really nice parts at great prices.

The '71 and up round tube swingarms can use standard XS650 aftermarket bronze bushings, but the early swingarms use smaller bushings, so I got a new set of stock nylon bushings from boats.net.

I'm using All Balls tapered bearings up front.

The top race of the tapered bearings sticks out from the steering head slightly increasing the distance between the fork clamps. This isn't an issue with mine since it won't have a headlight, but can cause problems if using stock headlight mounts, so you can get just the lower tapered bearing part #99-3515-5 and use stock balls on the top. The bottom takes most all of the load.

Here are the mx clamps. I spent some time on the bottom clamp, but just brass brushed the top for now. I still need to get new hardware for them.

Thanks! Those clamps are 34mm, and were used on the '73-'74 Yamaha MX250, MX360 and SC500.
