Broken chain guide bracket.
This, and some other damage, indicates the bike has had a history of chain derailments. Thus I decided to build a chain guide from scratch.
Step 1 - Fabricate a new bracket from 1" x 1/8" steel and weld it to the swingarm.
New bracket welded onto the swingarm. Luckily I had some red spray paint that's a close match.
Step 2 - Using the same 1" x 1/8" steel, make two side plates. Drill a couple holes in both plates. Use a couple shoulder bolts, nylon spacers, washers and nuts. Voila!
Instant chain guide.
Step 3 - Add a nylon roller from the old chain guide removed from my GasGas onto the lower spacer.
Looks good, no?
If I can scrounge up another freebie nylon roller I'll slip it over the top spacer.
