More then one way to look at warranty.
My personal view is that a 1 year warranty you have to argue, beg and wait in line for is non existent. I'm not willing to invest the time it takes to di(k around with these people despite the fact that locally my bike would likely go to the front of the line.
I can see the point, in particular with extremely complicated motorcycles full of electronics that can be very expensive to repair like the late Ultra's and touring bikes in general.
I believe you can never walk the middle line in life for long, you either commit to one side or the other.
You want to play, you got to pay the price and take the risk.
Any of the moderate compression kits with big bore, heads, cams and tuning will get you there. There is also nothing wrong with riding a stock bike. The rider is the biggest factor, the two or three guys I have to work at real hard to keep up with all ride near stock bikes, and I'm sure there are plenty more out there.
