Lament may have been too strong a word. Is there a reason to not turn the no. 1 main bearing journal down to the 55mm T1 size?

sideshow said it. The OD of the 5 bolts holding the flywheel on won't fit in a 55mm circle.

Whoa, not sure what I am looking at; http://kompressor.typ1motor.de/
Check it out to me it looks like he is using
  • Early 1.6/1.5 case (no oil filer/block off hole)
  • Stock late MX oil pump (4 bolt only)
  • Later wasser cam (4 bolt only)
  • 210 Bus flywheel
  • Stock carburetor 1.6 era
  • Stock air cleaner (but butchered)
  • Single port era cooling system (steel cooler in shroud?)
  • A 2 or 4 coil ignition, whatever it is its not distributor based
Very nice work, now how he got the wasser crank and cam to fit as now I like the idea of a dual pattern stock'ish cam?
Yeah some may call it overkill, but you can't have too much overkill.

Yes I tied that all ready, kind of looks like he cut the #1 case side to fit. Back tracking up to the root side not seeing any other tech.

It may be a viable way to salvage a t1 case if its in otherwise usable condition--- given a new mag case costs darn near a ~grand these days.
All t4 mains starts looking like a really good plan...?
Addendum to Newtons first law:
The longer a vehicle rests on jackstands,the more likely it is to remain that way...

Ps (off topic):
Some original thinking on that engine.

He’s gone with a non-dog house shroud so the end castings can be reversed and routed behind the fan. For oil cooling he’s deleted the stock cooler and added a Mexican oil pump cover (with screw on oil filter socket), plus a (Mocal?) thermostatic sandwich adapter (to route oil to the cooler above 80C), plus a small BMW motorbike oil filter. Not seen that before.

Not sure what I am looking here;

But CB seems to offer some sort of adapter bearing for flanged cranks, something I have never messed with. Is this a possible route for bearings?

Looks like a very good possibility, although I don't see any options for oversize case or crank.
Also requires all t4 mains, this is not a bug, but you'd have to make sure DPR or such can make an all std t4 journal crank.
(or just pay $200 for the two bearings you can use if your wbx crank and case is std/std)
