I'm gonna give mine a 4. Granted I bought it used but it only had 16,000 miles on it. It had already had the update kit installed, not sure if it was for 2nd gear or output shaft bearings. It had a warped rear rotor when I got it but that could have been the previous owner. It had the paint can rattle early on but not since I installed the cam chain adjuster spacer. It's had the high idle problem off and on since I got it. Have tried two different TPS's. I'm working with Hanso on an updated base tune that may finally solve that problem. Noticed rear rear wheel bearing were failing at last tire change and replaced them. At 50,000 miles the output shaft bearings failed catastrophically in Colorado and tried to lock the rear wheel at about 70 mph in a curve
. Water pump leaked and had to be replaced. Rear splines are shot even though they have been slathered in moly grease at every tire change since I've had it. Not the most reliable bike on the planet. I'm fortunate that I can do my own repairs or I couldn't afford to own this bike.
HOWEVER, I love this thing like no bike I've ever owned before and will continue to wrench on it if that's what it takes to keep it under me. It's like a high maintenance girlfriend who's a really great f_ck
