Heads: valve seats refurbished, valves refurbished, one valve guide drilled and put in sleeve, seals replaced, cams saved, five rockers replaced
Cylinders: another 20-30,000 km of life left. New nicasil or something else....
Pistons: no cracks, all rings good, compression test good
Crank and rods: good
Gear box: output shaft replaced because of wear under the sprocket, gears a little worn
Cases replaced: crack by the belt drive, crack at front right motor mount
Starter 'clutch': spinning a little, replaced
Runs: ~10 degrees C hotter, 10% better mileage
Issues: not-perfect intake port & polish rom previous builder holds it back, oil leak rear right cylinder vs cases (the usual place)(plugged, but still leaks)(updates to follow)

What do mean? "Finished"?
Back to the ~99 "Ducati calculated" bhp.

Some of it is older and some of it is newer, but very little is original.

I don’t know if Ducati has changed the 797 engine over to the plain beatings yet, but that could be a modification / upgrade if you care to next time...

Are cracked engine mounts common on the high mileage bikes?

Plain bearings.... where?

Not to my knowledge, but this might be connected to a big track highsider. All engines will crack sooner or later, so old age might be the reason...
The more common crack area is behind the belt drive shaft / front of main bearing.

I know the plain bearing cranks started with the 821 back in like ‘15. They’re slowly converting the engines to plain bearings. I’m not sure if that process has trickled down to the 797 engines yet. Which is also the same engine as the Scrambler 800... Just wanted you to have options & maybe a more reliable engine and/or a couple more HP.

Never finished.
Not even job complete when there is an oil leak.

Duck-Stew
Are you saying the crank main bearings are now sleeve type (bottom end rod bearings? Does that reduce friction? I can see the weight savings. I presume the insert would be a full circle not 1/2 like rod bearing inserts.
Thanks, Sterling
