The clutch cover issue is resolved. There is a newly designed piston/sleeve/seal kit out for it.
The turn signals were also a known issue, the new ones do not burn out. There was a problem with a portion of the waferboard burning out.
Rotor warp? I amnot sure about this one. The factory pads will leave deposits if you race the bike due to heat. Mine did it after a track day from hard braking. The fix was to rebleed the front brake...take it up to about 90 and burn the deposits off. The pulsing goes away and your braking feel returns. My solution for this is to upgrade to a good street/track pad for future uses.
The tire... not really Buell's fault. The PCIIIs are GREAT street/track tires. They are not known for having exceptional longevity though. My suggestion to you would be to buy a harder compound tire that is not so soft. Especially if you are one straight flat roads and hardly ever go to the track.
My bike has been back to the dealer for the clutch cover, turn signals *I would bring the old one in and put the new one on in the parking lot* and the instrument cluster. Other than that it's been maintenance free and a sheer joy to ride.
If you continue to have serious issues, work with Buell Customer Service and be patient. You are less likely to get help and get your bike issues resolved if you start to complain and bicker.
Hopefully your dealer is good with Buell support. Sadly this is IMO the most difficult issue with new Buell owners... EG: Learning the hard way that not all dealers are equal when it comes to knowledge, service and helpful attitudes.
Best advise... be patient and let BMC take care of your issues. It's under warranty, THEY WILL GET YOUR BIKE RIGHT, just be patient and understand that no matter what manufactuer is out there, parts/issues are going to happen, especially on a newer model.
Hope this helps.
