CMB 91RS M-line direct drive, comes with outboard conversion kit for Lawless gas drive. Conversion kit includes fronthousing with bearing, o-ring, oil seal and steel bushing, flywheel& cone, squaredrive, baseplate for the Lawless drive, backplate for 18 mm round neck carbs, crankshaft for ob conversion kit and a 91 GPX tuning kit. (basicly what you see in the pic)
Price shipped to you is $ 1100,- PP as FF or pay the fee.

If you`re not interested in the extra OB stuff I`ll take it away and sell / trade the engine alone including a header.
Then price is lowered to $ 650, -

Btw, engine has never been used, but it has been cracked open to make some internal measurements.

What kind of measurement tools are you looking for Joern? Calipers, mics, bore mics?
Mostly 3 point internal mics, if analog it has to be metric as 97% of my jobs are metric based. And it has to be well known brands such as Mitutoyo, Mahr, Tesa or similar.
However I`m most interested in workholding stuff, such as zero point plates and equipment, self-centering vises, dovetail vises etc etc

I have a couple of options:
Mitutoyo 568-976-10 SMB -0.5 CSR .275-0.5" (6.985-12.7mm) Borematic
Mitutoyo 568-977-10 SMB -1" CST 0.5-1.0" (12.7-25.4mm) Borematic
Mitutoyo 468-263 HTD-0.5"R .425-0.5" (10.795-12.70mm) Digimatic Holetest
Mitutoyo 468-971 HTD-12RST 6-12mm Digimatic holetest

These are all used in good shape, but need a cleaning and likely new calibration. Oil has gummed up a little making them sluggish.
I am only interested in the engine, not the OB parts. Each set is close (+/- 50) to the $650 price on the used market.

Those are very nice tools for sure. They are discontinued though, I will need to check with my supplier of metrology tooling if they still can supply parts for this tools. Do you have the second setting ring for the 568-976 set, or is it lost?
And you want to trade one of these sets in the 91 engine, right?
Would you concider trading two sets for the 91 M-line + the 45 GPX?
I`ll get back to you after I have spoken to my supplier 🙂

Hello Joern, I am just heading to Europe for the week so i will need to check when I return next Sunday. Yes I would consider trading 2 sets for 2 engines.

Hello Tyler,
My supplier of metrology stuff just replied to me that unfortunately Mitutoyo can not provide any spareparts for the borematics, meaning they are not worth much to me. I`m sorry
