A new member fromFlanders
« on: December 05, 2019, 04:13:22 pm »
Hello,

I am a 61 year old Guzzi fan from Flanders in Belgium. My Nuovo Falcone is an ex-carabinieri Falcone from 1970. I bought it in 2002 from a BMW-rider who used it only for riding in the rain. He didn't want his BMW's to get dirty. The Falcone was his dirty bike! When I bought it, the NF had 10050 km's on the counter. Now I passed the 65000 km mark.
I continued to ride it in unrestored condition. Apart from normal maintenance, I changed the clutch for a second hand one, I also gave it a longer gearing with a 33 rear pinion.  I also regrounded the valves. The rims were replaced with aluminium ones and new spokes. As the paint was getting very poor, last year I decided to give it al full cosmetic make over. I chose to give it, what I call, the V7 special look. My friend rides a white V7 special from 1970 and I always liked the colours. I am very pleased with the paintjob and the finished bike looks great. However, and this is the bad news, since the rebuild the gearbox is getting worse and worse. It is almost impossible to shift into third gear without it jumping out again. As Flanders is really flat, for the moment I shift twice from second to fourth! A NF can cope with this, but of course this is only a temporary method. This winter I will remove and split the engine. I suspect the problem will be found with worn gear dogs! I will keep you informed.

Welcome Vusette; there's not much traffic on here these days I'm sorry to say, but I hope you will find some useful material on here, and we look forward to hearing of your gearbox investigations. I hope they go well, and that your problems are not too large or expensive!

The engine has been stripped almost completely now. What remains is the crankcase with the gearbox and crancshaft inside of it. Flywheel, primary transmission and clutch have all been removed. I find it easier to remove all these parts with the engine still in the frame. That way the engine becomes much lighter to remove from the frame. Cylinder and piston are also removed. I was pleased to see that de piston (still the standard 88mm size) is in perfect shape. I will however fit new rings. also I noted some pitting on the tappets. I suppose this are the same tappets as fitted in the later V2 engines?  The camshaft seems ok however.
Tomorrow I will open the crankcase. What horrors will I find there.

Morning Philip; sounds like you're making good progress.
I have never had to enter the crankcase of mine (yet) so it's interesting to hear your approach.
My tappets also were pitted on the top surface when I repaired the top end, and I replaced them at that time.
I'm not sure if they are the same size as the V7.

Hello,

I am a 61 year old Guzzi fan from Flanders in Belgium. My Nuovo Falcone is an ex-carabinieri Falcone from 1970.

Wotcha.

I too am a 61 year old Guzzi fan - only I'm from the Midlands in the UK. 

At least once a year a few of our motorcycle club members head over to Ypres for a week or so in the Summer.  This year we hope to be there from June 19th.  We will be using our usual camp site  http://www.jeugdstadion.be/

In the meantime the engine has been stripped completely.
What was wrong? Some pinions in the box had quite worn dogs. I replaced 4 pinions. 2 of them I bought from Shubert and the other 2 from Escher.
All rather expensive and I'm sure that replacing only the two most worn items would have solved the problem.
Opening the engine however takes some time and work and so I decided to replace as much as possible while everything was on the bench.
Hopefully this will save me from having to start all over again in a few years!
The crankshaft is ok, also the piston and bore look like brand new. As a matter of precaution I will also fit new piston rings.
The wear in the pinions dogs was definitely caused by the bad shimming in the factory. The 3th and 4th gear dogs wear only in contact for 50% of their hight.
It took some time and probably closing and separating the crankcase halves more than 10 times but now I'm pleased with teh result.
I also took a look at the valves. They had already been replaced once, some 40000 km's ago.
The exhaust guide was a loose fit in the head.
As I know the bad reputation of the original valves I decided to fit 2 new standard valves. Th exhaust guide will be made from new to give it a better fit in the head.
The inlet guide will also be replaced but with a standard new one.
As I write this, the crankcase now has been closed definitely. I'ts ready to refit it in the frame. The rest of the parts (clutch, distribution, piston, cyilinder etc..) will be fitted while the engine is in the frame.

Too bad I can't add some pictures here! I have made pictures of all the various steps during the reasambly of my engine !

Well done Vusette; that sounds like an excellent job.
You can't add pictures here, but if you upload to Flickr or similar, you can link to them here?
Would be good to see!
