Rare Sporting Harleys on US eBay

I wouldn't have much use for it, but I still would love this alcohol-fuelled 1927 Harley JD hillclimber. It's up on US ebay with a starting price of just $9999. It's in Washington state.
This is the same model engine that Homer Knapp used in his race bike.

The same seller is also offering this rare 1953 Harley KR750 flat tracker.

Thanks to Martin H in Germany for the link. GI
