Matchless G9 Engine strip down...

At long last!  Now that some family commitments have been attended to, I am able to get back on track with my many (read: many, many, many) projects.  I have been waiting a year and a half to tear into the bottom end of the G9 engine;  This should keep me busy until my friend can finish welding up the Beetle.

The Verdict?  So far things look very good!  The con rods are very clean and straight, with no nicks or scratches.  The crank bearings are very good as well and can likely be reused.  I was pleased that the oil pump turns freely and the bottom end was coated in a film of oil.  The engine was certainly rebuilt at some point as the 'sludge trap'  bolt has been removed and replaced several times.

 Matchless Twins lack a true Sludge trap, instead having passages that can be easily cleaned out periodically.  Despite having +80 over sized pistons, this engine was very carefully looked after.   A shame really that the rest of the bike didn't receive the same treatment and survive in the same fashion.  I am sure that some of it is in that big pile of parts, as for which ones?  That is a secret lost to time.

More to come!

Any time spent with King Dick is quality time.

As a side note, 'Krave' is probably not fit for human consumption.  I, However have no issue using the box to catch decades old oil drops.
