Nice cutout LonerRanger! What interval does Guzzi recommend inspecting/replacing the timing belt btw?

Apparently my big block has a morse chain and hydraulic tensioner for timing. Can't advise on interval for the belts versions. Believe the cut away is of a small block Guzzi.

Looks like it's easy to adjust the valves. I'd think the belts that drive the cams would last many miles like cam belts in most automotive engines. The Guzzi service schedule should show the belt inspection/replacement interval.

It is beautiful, inside and out. I'll take a V11 LeMans, which I think is only a 2-valve.

The belts are driven off the old camshaft drive, so they are half time and should last much longer than engine speed belts. Rockers are very much like every Guzzi, on a separate plate which unbolts from the head...and of course very easy to get to.

That's awesome, at least you'll never have to do a belt inspection/replacement with your model being chain drive! And yes, the valves look incredibly easy to adjust, just those two things alone will help keep maintenance costs down tremendously.

Iím just learning about Guzzis and Iíve been looking at a V7 Stornello which comes with what I think you Guzzistas (?) call a small block. I was very surprised to find out that itís got a pushrod valve actuating system. Still seems like a pretty good bike and Iím scheduled for a test ride soon as things melt and dry out.

Maybe they make different versions of the small block, some with timing belts and some with pushrods.

Too bad it's ancient air-cooled... smile go to all that trouble with fancy dual OH cams and 4 valves per head only to stay with antiquated air cooling. Horrible for anyone that lives in the south or desert regions!

Radiators belong on cars, along with windshields and electric starters. Been riding air-cooled bikes in the desert all my life and never had a problem. Water cooled engines make more HP per cc but at the trade-off of weight and complexity. To each their own.
