    That's really cute.

    The last experience I had with a small block was my wife-at-the-time's V50 in 1980.
    It was really pretty and easy to ride, but sort of blew up on a long trip.

    Are the new V7s a lot different?

    What did it do? Drop a valve? this was the most common issue with the early smallblocks. One has to remember that the V35/50 was designed to be price competitive with Japanese machines of the time. Interestingly in your pic you show it's direct competition, the CX 500 Honda. When the V50 was launched in the UK it was actually CHEAPER than a CX!!!! Unfortunately corners were cut. one of those corners was the valves. They use very thin stems and while they are *adequate* they were only barely so.

    The exhaust valves in any engine are the hottest part there is. Even if an engine is in good tune the necks of the exhaust valves will be glowing dull red in service. The gasses exiting past the valve are only slightly cooler than an oxy torch and the only way valves can dump heat is through the seat when they are closed and through the stem/guide interface. Once the mixture gets too lean or the ignition timing gets out and it is very esy to over-stress the neck of a valve.

    Most engines have valves that are built very conservatively. alas with the early smallblocks this isn't the case. Poor tuning or simply letting the heads get oily and dirty, (Dirty fins can't dump heat nearly as effctively as clean ones and smallblocks were a bit under-finned anyway.) will result in valves shedding their heads. This is the reason why it is VITAL to check your valve clearances religiously at 5,000km intervals on an early smallblock. As soon as you notice the gaps start to close you whip the heads off, (Takes about 15 minutes each side! As Styx sez they are didiculously easy to do the top end on.) and replace the valves. They aren't very expensive whereas a barrel and piston kit is!!!!

    The later, Baby Breva and later, smallblocks seem not to have this problem and I can only assume it is down to superior materials being used in the valves as nothing else in the motor has changed since Jesus was in nappies! As I've said before the ONLY modification I dvise, and I advise it strongly, for the modern 750 Smallblocks is fitting a Guzzitech sump extension. They do run very hot and will drink their oil VERY quickly if run hard in hot weather. they also run hot generally so use a top of the range full ester synthetic oil in 'em unless you want problems down the track.

    One bonus, that hopefully you won't get too involved in, it's a piece of piss to strip down and rebuild.
    Welllllll, that is some verbiage.
    I helped a past girlfriend replace a rear oil seal on her V50 that was weeping onto the rear brake disc. we just lifted the frame off the drivetrain and got to the seal. not very difficult at all. It was one of the first home repairs she ever did and it was not a problem for her. at all.

    Indeed it did.
    I checked valve clearance on both bikes 300 miles into the trip with both in tolerance.

    1000 miles later the V50 puffed a gout of smoke from the left cylinder which had me pushing it for miles to the next service station. A U-Haul ride to the nearest dealer had it getting a new top end from a fellow TZ pilot while that wife and I rode two-up up Mount Washington.
    I always liked that V50.
    But it's a good thing there were no bridges to throw it over on that long push.

    Don't let the top end leak. Rocker cover gaskets are really cheap. Don't try and re-use them.

    Took the girlfriend out for her first ride on the Guzzi yesterday, loved it! Much safer than the R1 for two up and a very pleasant afternoon out.

    I was in San Francisco this past weekend and I saw someone riding a V7 Classic up Franklin. Sweet! I thought of you guys.

    First service done today at Corsa Italiano with a 1000kms under her belt and all is well. Fitted a rear rack for pillion convenience and to accommodate a tent for a trip to Olivers Mount in Scarborough that i've promised myself later this year. The rear suspension has been firmed up and instantly feels more to my liking. She's a great bike round London with a fantastic turning circle and the Mistral exhausts, with baffles still in, sound just right. Fantastico!
