Hello!
« on: September 03, 2017, 10:14:28 pm »
Hi, all,

I'm a long-term Guzzi twin owner - 850T in 1997, added a LMV in 2001, sold 'em in 2008 - worst day's work I ever did!  Back on a Cali 1100i last year.  I've joined the local VMCC recently and have been lusting for a bacon slicer since seeing a couple here, but they're over my pay grade.  The NF, however, fits the bill nicely.  Looks like it could be an every-day gentle ride, and a good bit lighter than the Cali for bimbling.

I'm in the research phase just now, but I do think there's an NF in my future....

Welcome Paul; the NF is certainly far more affordable than earlier bacon slicers, and a good one can be very involving and satisfying, as long as you're not in a hurry. Worthwhile trying before buying if you're anywhere near any of the dealers with one for sale. It's an acquired taste, but strangely addictive. Wish you success  ;)

Well, I finally did it: I should take delivery of a FrankenGuzzi before the MGP starts. 

It's a '72 NF Military, but 2 POs have done a partial conversion to Civile.  That is to say the tinware has gone, the frame is painted red and the tank etc are white: a nice paint job.  It still looks 'Military', as there's a single seat, Mil tank and rear carrier...  Some serious money been spent in the past: alloy rims, 8mm valves, new fork legs and springs, SS exhaust with (I think) a V7 'silencer'.  Oh, and a Civile airbag.... 

Other than getting it through the Manx test I plan to do nothing beyond riding it (and maybe replacing the seat springs: let's see how comfortable it is).

I think it's name is 'Bossom'. (Sir Thomas Beecham: 'And what's your name?'; Man: 'Bossom, Sir Thomas'; Sir Thomas: ' Ah, I see.  Neither one thing nor the other')

What's the current thinking on unleaded petrol nd he NF?

It's going to be fun!

Congratulation for your NF back on the road,

 Based on my personal experience with the NF,

the unloaded petrol ( 98) it can be used safely. (I do avoid the E 95- 95 )

However, it is advisable to make small adjustments to the (timing) advance:

with the old loaded petrol, the starting point of the ignition (indicated on the flywheel with the marking "AF10")  was at 10 °.

With unloaded petrol, the advance must be reduced to 8 °.

With regard to the increased wear of the valves, resulting from the absence lead in unloaded gasoline, it does not matter in a low compression rate engine like the Nuovo Falcone.

However ,occasionally (every 3 of 4 full tank) the appropriate additive shall be added;

I've no idea what the timing is on mine. I just lined up the scratch marks on the points back plate..... However being brought up on manual advance bikes I can feel when the timing is off. What's more significant with these motors are the advance springs. Too slack and they are massively advanced straight off idle and too strong and it won't pick up off idle. Don't ask me how I know..... Oh and run the valves on the slacker of the two recommended settings and pay no attention to North Leicester Motorcyles's recommendations which are not fine if you run the motor hard. If you have  the carb misbehaving after a downpour take the fuel cap apart and fit a tight rubber O ring round the square thread. Due to the Dell Orto float bowl design these motors don't run badly when they get a smidgeon of water in the fuel, they stop.  And mine doesn't start until all the water has collected back in the float bowl and been blown out with compressed air, some hours later....... Don't run the idle really low as the cams only get fed with a bypass valve once the pressure is up. Running it at lowish brit single revs is fine on mine. Don't use car oil as it causes clutch slip. If you do have a bit of that change the oil and run for a while a couple of times to flush out the car additives. I use Morris V twin oil, after all a single is half a V twin.....  North Leicester say Moto Morini clutch springs are identical. They were very helpful.

Thanks, Randall and Cloggy.  Info to file away till delivery day!

What additive is recommended?  I have never had to use a petrol additive - my 850T didn't mind unleaded fuel, and the T3 came with lead-free converted heads (complete with certificate!).  I have always thought of additives in general as equivalents of snake oil, but I'm happy to be corrected!

 An engineer mate of mine who used to own a motorcycle business told me recently that they are essentially snake oil.....

with all respect for the engineers and the snake oil,

is like carry a spare inner tube, you will never have a puncture;

I have been using the load replacement additive,  since 15 years on my NF and I have never had a  valve dropping ,

 perhaps I'm just lucky

Welcome to the fold Dunders. You will find the experience 'involving'.... 8)
I've never used fuel additive, but found both valve guides very worn after 20,000 km.
No sign of damage to seats.
In my view, an additional oil feed to the inlet rocker is essential; not a luxury.
Posts on my rebuild and oil feed mod are on here.
Look forward to seeing some pix at some point!

Thanks, Banquo.

I've heard conflicting reports about the oiling mod: Chris at NLM says he's removed a number of such mods because they make the engine smoke (oil running down the valve guides).  The arguments for seem compelling, though, and Winter is Coming...

I'm hoping to get a couple of month's riding in before winter, by which time i'll have a better idea what needs doing/what I want to do to it.  I already know that I'll be looking for springs for the seat.  For some reason a PO has removed them.

I should take delivery in a week or so.  Pics will follow!

Yes, one of our members on here did suffer from oil burning after the mod, but then that won't happen unless the guides are worn quite badly, and it could be argued that the lack of oil contributes to guide wear. When my head was rebuilt to non-standard spec. the valve stems were fitted with oil seals anyway. If you take a look at my post about the repair, you'll see the result of no lubrication on the rocker face, and that was after only 20,000 km or so. I consider it essential. There's supposed to be a spray feed from the rocker spindle, but it certainly wasn't working on mine...
Your choice though...  ;)
Seat springs come up on eBay periodically, and someone either on here or on the Facebook group converted to hairpin ones. Lots of options.
Possible the previous owner was short, and removed for that. You do have the tractor-type saddle, and not the slightly longer one? The JNA (Yugoslavian) bikes have a longer saddle, and it doesn't have springs.
Just a thought.
