Remarkable thread. Just read it from the start. Lovely work Les. You have any idea how much money you have into this so far? (Having just bought a 73 GT850 :) )
Thanks, it (Your GT) looks like a good bike in the pictures (Maybe the front brake shoes are worn or 'something based on the lever angles and threaded adjusters)
I would do just as I wanted to do in the beginning, change the oils, maybe check the rocker clearances and ride it (since it has Gilardoni's) for a bit before thinking about digging to deep.
My bike started with the the universal near failing point so would suggest putting it on the centre stand in gear and rocking the back wheel, I would not want to see much more than 10 to 12 mm of movement out at the tyre.
The cost I am not sure of because this bike is an oddity, it looked like the 15000 mile bike it was sold as but every conceivable component that could wear out was pretty much just that.
I am not even sure if the paint is original, only someone knowledgeable could tell me that.
The bike cost around US$9000 landed in Australia, MGCycle got the most loyal custom/money @ US$5000 + post (Maybe $1000 over 14 orders) so there is $14000 off the bat.
Around 2000 € at HMB... The ring and pinion was AU$799 locally and so on, the 1000SP gearbox from San Francisco AU$700, wiring loom US$462 so maybe $20000 + , (US$14k/$20k depending on the exchange rate over the last 8 + years) that's why I joke about having 3 or 4 dollars invested in paint. (maybe a half roll of 'tin foil (and water) in the chrome restoration)
No offence meant to anyone, I do not build bikes to putt around the neighbourhood or dawdle down some back road, this will be a working bike which is why the cosmetics are as is but shown some respect given their age and condition, whatever that might be.
We will never know why it had worn out stock cylinders but already (ruined by chrome) on a first under size on the crankshaft, knurled internally valve guides.. etc etc.
In hindsight it would have been better (logically) as considered at the time (1 for 1 exchange rate) when the extent of wear was found, an incomplete 1100 or 8 valve bike imported to use its running gear for what would be a modern (disc) Loop Eldorado but it it would have been a Loop in name only.
The irony is I might now be one of the most knowledgeable people on the planet regarding the 1973 2LS brake Eldorado who has never ridden a Moto Guzzi.
The Mk2a 850 is up on the table the Moto Guzzi vacated, the 1949 Sunbeam up on another, War of the Worlds continues....... Spring is closer than it was yesterday and have wondered how far I could go on my BWS/Zuma 125 with my lightest camping gear.
Back to the (not yet) Spring clean.
