Mine has about 30k on the clock. I bought it as a non running project bike.
The PO was a dickhead that never adjusted the valves. He didn't do the doo until it chunked it at 12k, fixed the doo, but never even cleaned the oil screen. He just rode it until it wouldn't run anymore. I got it and fixed it for not a lot of money. Oh yeah, he also cracked the frame too.
I fixed that too.
It now runs like a champ. That motor and bike are really impressively tough. Considering what the PO did, it has no right to be alive right now.
