Mamba took care of the leaking fork tube under warranty by replacing the seals, and I don't know what the labor charge would be, but the parts alone would be almost $90. I did get thrown a curve on this maintenance, and it happened even before I'd left the building. Mamba's Service Manager, Jeff Granados, found me and gave me the bad news about the Dunlop Q3s on the bike. The rear had picked three small nails. A real shame, since I had managed to get the Dunlops to 2,680 miles with plenty of life left. In fact, I'm pretty sure I could have gotten this set to 4,000 miles, which is superb for a very sticky, compliant tire. Not, however, a fantastic wet-weather tire, which is why I had Mamba spoon on a set of Michelin Pilot Road 4 (motorcycle.michelinman.com; $570/set MSRP).
