Dennis Kirk was the only place i could find with this part in stock(tried 5 places in California first, even FMF themselves were out of stock). I Ordered it tuesday, recieved it wednesday via UPS red(Minnesota to So Cal in 18 hours!), installed the same day in 2 minutes, then loaded my bike on the ferry for the 2010 Catalina GP that afternoon. The part let me pass sound check and spark arrestor check with flying colors. Fit great and did it's job.
