Basically nothing. I had to fix a few things from dumb previous owners, and I've crashed a few times, so now it's down for restoration.
If your compression's low, check the rings before assuming it's more serious. They wear, but they are cheap and easy to replace.
Not a bad guzzi, can be very expensive. You can spend $4k on an engine alone. New owners often have about 12 months trouble while the bike settles down, and recovers from the previous owner..:)
I love this bike. I've owned dozens of the most exotic and common bikes available, and I can afford anything I want. At the same time it's a study in mediocrity. but does everything I want it to. It's as fast as I am, handles well, needs little maintenance and I can tour 12 hour days on it. Every bike I've had till now was a one night stand. This one's the marrying kind. I'll never sell it.
Well now, I agree almost totally with this. I have had a number of Guzzis and other bikes before, as well as alongside my old S3, and have kept the S3 as the 'bike I always choose to ride in preference to any of the others.
Now with 386,000km on the clock, she's getting a bit long in the tooth, but whenever it's a nice day and I want to have a good time, I wheel her out.
I have an S3 too, totally original. I agree with the comment. The bike rides very very well and I saw many V7 Sports, but never met another example from the S3. The colour scheme is magnificent. My Borrani wheel aren't perfect. I'm looking for a perfect pair of these.
