The Moto-Guzzi Nuovo Falcone VOC

It's a French Alcyon, so small you could almost carry it on the back of the mighty NF as a"spare".

Speedo drives off the front wheel, so no problem

My other Guzzi ? It's a v50 MkII ex police machine. It's in bits just at the moment in order to do something about it's gearing. talk about low geared, 50mph at 5000 rpm. I guess it's like that for use in the city traffic where acceleration was more important that high sped. Need of course to split the gear box away from the clutch housing  to get a the input gears, so it wont be a five minute job.

Nick,
Did you have to take any links out of the rear chain when you fitted the smaller sprocket? I have 33tooth one to fit some time and wondered if I might get away without doing that.

Having asked about an extra  oil feed for the valve gear, and then seeing that a ready made-up version was going to cost 101 Euro. I decided to make my own. Here’s how I did it, and the mistakes I made (so that you won't make them as well).

First I acquired a 8mm and a12mm single ended banjo union and matching bolt. These I took to my local hydraulic pipe service to have about 250mm
wire braided oil line crimped on. Next remove the 16mm blanking plug from the rocker box, drill and tap this to suit the 8mm banjo bolt. Note: the normal 8mm bolt has a pitch of 1.25mm, whereas the banjo was 1mm, so the 8mm tap that you  might buy at your local hardware shop is probably not going to do. Luckily I had a 8 x 1 to hand. However to prevent too much  oil being delivered to the top of the engine some form of restriction needs to be fitted to the system. In the professional made version this is achieved by  fitting a number 60  Dell'Orto  jet. These have a 6mm x 1 thread and happily this is a standard size, so the 8mm banjo bolt was tapped this size and the jet screwed into it's end. The OD of the jet was somewhat larger than 8mm so once fitted in the bolt it was skimmed down to size.
On the right hand side of the engine there is a “U” shaped pipe held on with 2 “Acorn” 12mm nuts. Remove the top one of these and replace with a short adaptor made from 19mm hexagon, about 30mm long, drilled and tapped to suit. Now this is where I went wrong, so pay attention. The banjo bolt as supplied was 12 x 1.5 (standard bolts are 1.75 pitch) As I had a 1.5 tap I thought all would be well, it wasn't. The engine turned out to be 12 x 1.25. So I had to make a new adaptor and banjo bolt. To do this I purchased a tap and die set off E-bay at a cost a less than £7.00, possibly not the best quality, but for what was probably going to be a single use I didn't think it mattered much. With the new adaptor in place the pipe was fitted, not forgetting new sealing washers and the job was done. The photos my previous posts  show the completed set up. 

Yes Nick you are right, it's a Dell'Orto carburettor number 60 jet. and you are also right in thinking that it's there to prevent too much oil going to the top of the engine. photo shows it in the top banjo bolt.

I too wondered if the jump form 35 to 31 might be too much. So I acquired a 33 tooth one, haven't fitted it yet (too cold and no heating in my workshop) but once I have I will post to say how I got on.
