Another question; I usually put 3 liters of engine oil in my Guzzi. Engine has and oil pan spacer (extension). Am I doing well so far with 3 liters or wrong?

Three liters of oil is proper. The spacer is to increase the air volume in the sump, not to increase oil capacity. This was done to reduce oil blow-by out the breather. Earlier versions of the engine without the sump spacer could generate high pressure within the crankcase, enough to cause excess oil blowing out the breather.

"Earlier versions of the engine without the sump spacer could generate high pressure within the crankcase, enough to cause excess oil blowing out the breather."

Earlier versions of this size of engine without the sump spacer could generate high pressure within the crankcase, enough to cause excess oil blowing out the breather.

IMHO the earlier smaller capacity typically 700/750cc don't require the spacer because they are less stressed and you don't get the build up of pressure with the smaller diameter pistons pumping up and down, so less crankcase pressure, if that makes sense?
You can still have oil blowing out of breather if you overfill the crankcase with oil, even with the 700cc engine.

Today I received an interesting call...a man called me and offered me the front and rear wheel from MG California Aluminium.. ;D and a very interesting price...I was wondering if the rear wheel from Cali Alu fits on my Guzzi's rear drive? Front wheel should match, but I will have to buy other brake calipers and front master cil.

Never ending story...... ;D

Console is finally cut  ;D
I only have to cut opening for instruments and some final touches (holes for LED's, polishing...)







And I managed to make mounts for the rear hazard lights:

Couldn't you sell on the bits you don't need here or on ebay?
Callipers would be easy to offload?
And front master cylinder to someone who don't change their fluid too often.  :beat_horse

Yes Rob, I could sell bits that I don't need, but I'm still in process of thinking whether to buy this spoked wheels or not...At the moment, I'd be happy to finish the bike and finally enjoy...On the other hand, I've already spent a good deal of money on this bike...so I really don't need spoked wheels in this moment...

Can understand how you just want to ride it, after all your effort and expense because that's what it's for.  ;-T

Need to respray my tank and side boxes but know it means, the bike will be off the road for at least 2 weeks.  :-\
But respraying should be done in drier warmer weather. Precisely the weather you want to ride.

The maintenance, riding conundrum?

 :D

Some more updates on instrument console; everything is done, except bending and some more polishing. This will be done today.

Sorry, images were made with my phone, so they are not top quality...





And as it usually happens...a little problem....due to the thickness of the material, instrument cups are to deep...will need to be shortened by about 5-7mm.. ;D



All in all, I am satisfied...

You are doing superb.  For a reasonable price I got the MG Cycle console and installed recently.  Keep up the nice work!

That white rev counter is on my wishlist  ;-T

Now I'm thinking to put my ignition switch somewhere else, rather that on the inst. console...Why? The thread that holds ignition swich is 8mm...my console is made out of 6mm material...there is only 2mm thread, not enough to hold the swich...Torture never stops.. ;D

Either that or reinvent the wheel and possibly destroy what I have made so far..​​...

That's beautiful...well done.

Maybe counter sink the ignition key hole on the back side of panel 2mm ?

Hi LeMans 1000, I was curious if that is the same tank you had before the restoration.  That gold green is classic and looks smooth with the red.   Is that a Lemans4 tank that has been hammered in?  Thanks buddy, and thanks for this thread!

CNC machine or router out the backside of the ignition key hole depth by 2mm. Then You won't have to start over or find a thinner sheet of aluminum.

Aluminum router bits:

This picture shows what I mean.(on a very big size of hole)

Yes, it's the same tank that was on the bike before. My tank is fully modified LM 2 tank.

Today's update...

Carbs are on the bike... ;D  Still need to mount rubber spacers for the tank, that's why it's still a little high..



Next; ignition lock....after a lot of thinking I decide for now to place ignition under the tank, on homemade bracket: for now...



So I made one...

Before doing any work with the switch and dashboard, put a 20-30A fuse on the wire from the battery to the main switch. Install in as close as possible to the battery.

A little more torture with console....

Finally mounted: But.....







"But" from the first part of the post....

Original console put the instruments between headlight and forks...my new console put the instruments higher...now I have a little problem with the cables...I'm going to use the T-cross that goes on instruments, for both sides...this will help me, so the cables don't hit the headlight....to much...If I bend a console a little more, there is not enought space for instrument cups.... ;D

So....again...tortu re newer stops... ;D

Like music... tension and release. You are in the tension phase. You will be relieved when you sort through this. I going through some of the hardships on my Lario project. It's been one hell of a great ride though. Keep at it you're doing wonderfully. Really looks great!

They are sitting up aweful high. What about dropping the headlight down, or making the headlight brackets longer and push the headlight out some.

How do you intend covering the wires to the idiot lights and stopping water and crud from getting in?

Iave made a number of instrument pods over the years and have had to answer all these questions  ;)

You could also get more clearance between the bottom of the guages and the headlight shell by...

Adding a collar ring to each of the gauges to raise the gauges about 1/2 - 1" above the surface of the gauge mount you made.

That extra space may allow you to bent the gauge mount down closer to the headlight shell ... maybe enough.

Now I'm thinking about this...headlight down a little bit and maybe to bend a console a little down.

On pictures maybe...when you look whole bike, it isn't that aweful... ;D

Sorry, awful is probably the wrong choice of word. Your doing a great job and without seeing the whole bike it just looks a bit high without a fairing.

It's going to be a beautiful Guzzi when completed.  Are those Delrin carb boots?  I need to replace the rubber boots on my LM IV.  I notice in the recent pics that you still have the original Paioli or Bitubo fork dampers with the cross-over tube.  I'd recommend replacing those with FAC dampers at some point.  That change, along with new Progressive/Wirth springs made a noticeable difference on mine.
