Always felt the smallblock, Tonti-frame Nevada would make a pretty decent cafe - looks like it's well on its way.

Stop by the "Wild Goose Chase" Moto Guzzi forum - the [mostly] friendly, helpful, knowledgeable group there will get you through just about any technical issue you might have with any Guzzi.  http://wildguzzi.com/forum/index.php

Looking forward to your progress, & welcome...

Thanks for the info, I have signed up and made a post. Seems like a wealth of knowledge there.


just use a standard connector-or use an insulated one and slot it for the "senterpin"

Thanks furu14, seems simple now you have shown me.



I bought a basic soda blasting kit to spruce up the carbs but it didn't make a blind bit of difference! I purchased some metal float bowls to replace the plastic ones and the difference looks a bit odd to say the least  ;D



I will get the bodies vapour blasted to make everything match nicely.


Today I began removing some unnecessary tabs from the frame to tidy up the space under the seat.

Before


After



Just need file the cuts smooth now and touch up with paint. Next job is to fabricate a plate to mount the battery, ignition and m-unit, I have decided to locate everything in the space under the spine. I will be welding this on top of the horizontal tubes as per picture below.

Nice looking machine you have there :)  Can't understand why your soda blaster didn't work out ???  I bought the el cheapo soda blaster and used it on all the ally parts including carb on a Greeves I just restored.  Did you try it on any other parts?

I tried it on the rocker covers and painted inlet manifolds and it didn't seem to have much umph getting rid of the grime there either, no doubt I am doing something wrong here as I have seen others with great results. I found a guy doing vapour blasting at a great price (2x carbs and manifolds for £15/~$20) and I am astonished by the results, it is like a factory finish. Just waiting on a few replacement jets to arrive as some of the original had chewed heads.





One question I have is how to connect the fuel supply lines to the carbs. The tank has two petcocks, can I join each petcock directly to each carb and leave it as that, or do I have to have a pipe joining both carbs by the way of a double inlet union? The carbs come with double unions attached but they don't appear on the factory diagrams (the factory tank only had one petcock with a T union spiting to two pipes however).


The support for the electrics has now been attached. Rather than have a pan over the complete space under the backbone I have made just enough behind the top tube for the battery to sit. I had doubts about the whether it would have been weatherproof enough to mount the more important (m-unit, digital ignition) stuff so I have decided to make a platform under the seat which should be much more water tight.




Behind the top tube


All of the new parts are going to be sanded and painted to look seamless to the frame.

I indulged in a new headlight last week after much deliberation, a 7-inch JW Speaker 8700 Evo 2 with DRL in chrome. The original bucket was too large so I have purchased a side mount Lucas bucket, cannot wait to wire this up to see how she glows!

All of the electronics have arrived now so I have spent today putting together a wiring diagram. I think I have most of it sorted but I am a little confused about the Alternator/R&R wiring. The original wiring diagram shows 4 cables going into the R&R;

2 Yellow from the Alternator (Saprisa)
1 Blue for the generator light
1 Red/Black that goes to ignition switch

The setup (Motogadget motoscope classic) that I have does not have a generator light so where does this go? Here is what I have so far.





I am a complete beginner at this and it will be the first bike I have wired, any advice or tips would be very much appreciated!

This is quickly snowballing into a nut and bolt rebuild. I decided to completely strip the frame and have it blasted and powder coated, it now has a lovely satin black finish. I was worried that the blasting and heat of the oven would cause the 2-pack bonder to give way but it held up well and looks great.




The heads and cylinders are currently being vapour blasted. I was so impressed with the finish on the carbs I couldn't resist giving the same treatment to the engine too, pics to follow!

I do have a question about the gearbox. Are you supposed to be able to cycle through the gears whilst it is on the bench? I am worried that I might have caused some damaged at a failed attempt at trying to open it up (so I could vapour blast the case). I unbolted it all and tried to open it up the wrong way AKA by sitting it on the bell housing and pulling the universal joint end out. I am worried that I have done some damaged and I do not want to reassemble the bike without having tested the gearbox on the bench at least. I have tried moving the gear selector, which moves up and down fine but it doesn't feel like it is clicking through the gears. When I turn the main drive or universal joint spline they are engaged and rotate freely.

Does anyone have any ideas? I would kick myself if I have done something terminal to it!

Well if all the gears are nicely lined up, you should be able to shift through the gears (my experience with jap bikes).
If the gears are not lined up, you should be able the shift through the gears whilest turning (directly or indirectly) the primary gear shaft.

It ain't about showing up on a bike that the loan officer at your bank, or your parent's inheritance bought for you. It's about skinning your knuckles, straining your back, developing some blisters on your hands, breathing varsol and paint fumes,taking measurements and making mistakes.
It's about standing back, after the dust settles, and being able to say when people ask, "I BUILT it!"

Wow, nice looking bike. Those carbs did clean up well.
I am pretty sure that the gears should engage when you operate the shifter as you turn the output shaft. Once engaged, it should get difficult to keep turning the output shaft.
Are you moving the shifter enough? With the wonky linkage that those things have, it can be tricky.

Thanks for the suggestion japstar. It doesn't seem to want to shift through the gears with a static or rotating primary gear shaft.

Oh if only I had the foresight for my first bike to be something well engineered like a jap bike  ;D

Thanks Rusnak, can't beat that vapour blasting for a lovely bare metal finish. Got the heads and swing arm being done as we speak.

When I rotate the output shaft the input shaft rotates also, so it is meshed in gear OK but it doesn't seem to be shifting at all. When I move the shifter I get good resistance from the spring but I feel it reach the top and bottom without any sign of it shifting gears and I cannot find neutral.

When I move the shifter fully down and then fully up (and vice versa) I do feel a slight notch but it isn't a gear change. The output shaft seems to rotate with the same force applied and neutral cannot be found.

I might have to chalk this one up to me being a bit gung-ho with the rubber mallet.... I have taken a look at how to dissemble the gearbox and it needs a few specialist tools that are rather expensive, it might be worth taking this to get looked at professionally. The silver lining is that I can get the gearbox case fully vapour blasted once stripped!
