Heck, it even has a T-3 headlight bucket... That said, I wonder if it could be a Mille GT, that would explain the front end and peg hangers.... The instrument cluster has Lemans II/cx100/Early SP written all over it. Not the big tach, little speedo of the Lemans III/IV...

I have built a few FrankenGuzzis in my day, this one is a real puzzler...

No, the frame is older as it doesn't have the breather connections.

*Assuming* the Mille is the same as the Strada, it uses the LeMans frame. Take the body work off of the Strada, and it's the same as the LeMans 1000.

I have to say a big "THANK YOU" to member "LeRoy" for sending me a CD full of useful things about MG. Wiring diagrams, user manual, workshop manual etc....Once more, thank you very much, I appreciate the help and your goodwill.

LeRoy's stuff is awesome. He's a great asset to the Guzzi community.  ;-T

Finally....new crown wheel and pinion drive. All new bearings and gaskets. All tested, no errors. The only thing that's missing is new oil seal.   ;D




All clean:


Next; to clean wheels...

just a reminder Brake Cleaner doesn't play well with seals and rubber bits...best to keep the two seperated

A little help please...In this moment, I'm rebuilding brake sistem (brake calippers, new pistons inside...) and while I'm doing this, I was thinking to also rebuild rear brake master cylinder.

This is the model:


Now....how to take piston out of cylinder?
On Google I found this:

....Remove the master cylinder, dump out the brake fluid, take off the lever and check to see if there's a circlip holding the piston in place. (Some have them, some don't). Remove the circlip, if applicable, and insert a slender drift into the fluid's exit orifice (where the line connects), and smack out the piston. While Brembo offers a special drift for this, an old motorcycle spoke of the correct diameter will suffice.

Is this the way to do this?
My doesn't have circlip....or I don't see one....

After a long pause, finally, I have time to go back to my bike....

In this long period of time I have done some things: sandblasted and powdercoated the frame and the rest of metal parts, prepare fuel tank for painting.






Engine is prepared for the frame:


So far...so good...next month all other parts will be painted, in the meanwhile, I have things to do...put engine in frame, put front and rear fork, and start whit wires....

Thank you.

Here is more pictures of frame parts; I'm very satisfied with how the powder coating was done. Much better than usual paint...






Engine and gearbox has been completly rebuild; in engine: new pistons, main bearings, big end bearings, new valves, valve guides, valve springs, timing chain.....in gearbox; all new oil seals and bearings.

Here is some more progress; engine is in frame, rear fork is ready for mounting, final drive also. Some smaller parts on the frame (coil holder etc..) are zinc coated. So far, everything is ok and with no problems...hope it will stay that way...

Hm....good question... :)

My next plan was to buy new tyres. Here in Croatia is a little problem with my dimension, so I have to wait a little longer for delivery...

I powdercoated my frame when I rebuilt my Lemans 3, pay close attention to making clean earth points on the frame for the wiring and make the main earth from the battery one of the battery tray bolts on the gearbox not the joint where the battery box and the frame connect. You can also run earth wires direct from the battery neg terminal to the steering yoke and the tail lights. Saves a lot of head scratching and swearing down the road.
Nice work keep posting.
Cheers

Great work.  If you run into problems with hooking up the swingarm.  It might be easier with the rear drive off.  Less weight to wrestle with.
