I'd appreciate hearing from fellow WR owners on how they've recovered from this. Options I see are:
1. Replace the swingarm
2. Get it welded.
3. Fill with quicksteel.
4. Ignore it, and keep riding.
All of the options include replacing the chain slider and chain...
haven't done it myself, but I have read everything i could find about this before buying a WRR.
Personally, I'd go with #3, and as you said, install new sprockets, chain, and seal-guard.
On Page 3 is a write-up by a guy who used JB Weld or similar to fill in the grooves: http://wr250rforum.forumotion.com/t4...eaten-by-chain
