Moto Guzzi
« on: May 17, 2017, 11:49:56 »
Should be a fun, and hopefully simple project.
Got rid of my Norton.

Bike was a tone of fun and I very much enjoyed it.
But it became redundant in my garage.  While I did ride it to work often, it really was a more "point A to point A bike".
I would rather use the Seeley CB750 like that (and I need to focus on finishing it)

So the search began for something comfy that I could not only ride to work, but take on a weekend trip with the girl.
She wasn't a fan of the Norton for good reason, and my CL450 doesn't have the legs for two up trips.

After some wheeling and dealing I ended up with a 1970 Ambassador Moto Guzzi!

I think it will fit the bill rather well.

It appears that the bike was restored in the Mid 2000s.  A fair bit of money was spent on it, but it saw little use.
Has been sitting for the past few years, so needs a solid service at the very least.

Forks seem frozen.

Has a nice alternator conversion.

Carbs need to be rebuilt.

First round of needed tools/parts

Step one in any respectable build to to tear the bike down to the frame.....correct?

I had not planed to mess with the forks until after the transmission was out, but in moving and shacking the front end freed up. It seems that there are no springs in the forks for some reason.
Guess I will have to order some.

Alternator, incase I need a spare.

Found that these stupid clips were not holding the cap very well. I was able to bend them a little bit, but I would like to see if there are any replacements or improvements out there.

Looks like during the restoration that a new harness was made and modernish electrical block installed.

In case you do not remember, or I forgot to tell you, the rear main seal on the motor is leaking. Or so the PO told the PO.
I had thought to be lazy and just fire up the bike to see how bad it was actually leaking, but thought better of it. I have the CL450 to ride every day, so no need to half ass the Moto Guzzi.
That and I have grown to rather like the bike so I wanted to do the right thing.

Lucky I did, while I still have not gotten deep enough into the motor to check the rear main seal I have found a few other small jobs that need doing.
I know it is the biggest cliche in this hobby for the current mechanic to bitch about the "last guy that touched the bike"......
BUY here it goes!

The fork spring thing is strange to me.
MANY of the bolts are covered in anti seize, but not actually tight!
Much of the hardware has been replaced with generic SS stuff.

Have no fear though. I enjoy this kinda stuff. Very much looking forward to crossing a bunch of small jobs off the list and learning what makes a Guzzi tick.
My hope is that it all pays off in the end result.

I did not pull the fly wheel last night.
It got late, I got lazy

Kinda not sure if this is going to need to be replaced.....

Next on the list will be to mock up some florist foam and decide how much of the rear loop I will have to cut off for my new seat.

Well the bike did come with a solo seat!

I do need to find a "radio" rack to work with the solo seat.
And/Or a "beer rack" to work with the OEM seat

Engine on the bench for better access.

Pulled the rear main seal bearing housing thing.
SUPER easy with special tool.

The offending oil.  I actually think most of of was coming from the lower bolts not sealing properly.

Looks like someone already addressed the cam seal

Bike had fresh oil though.

Kinda cool view.

Honestly dont think this bike was ever run after restoration.

Replaced the rear main seal(old one was hard as a rock), the bearing gasket, the two oil pipe crush washers and the other pipe gasket.
Figured it was a good idea "while I was there"

Alternator bracket that Grandpaul was asking about.

This just looks REALLY bad.

Well I have some information about the springs.

The winner was "no springs installed"!
Unsure why that was the case.

Since I had to take most of the bike apart for different services I figured I might as well rebuild the forks at this time.
As you saw I bought the correct tools and parts for the job.
Everything came apart fine, almost too easy.
Some of the seals on the bike have turned dry and hard from sitting for so long after restoration.

Also fork rebuilding is a cheap thing to check off the list.

Not only did I buy the fork seals, but I bought the lower bushings.
But then my troubles started!

First the OD of the lower bushings is to large to work with the fork legs.
They bind and just do not fit correctly.
It is almost like they were not finally machined.

After I found that out I decided to just put the old bushings back in and call it a day.
Nope, cant do that....
The tool broke!
Freaking thing has a 1/2 drive, would think it would take some torque.

So finally I spent the rest of the afternoon chewing up the lower forks trying to get them apart....but no dice.
I tossed everything in a box and went home.

Contacted MGCycles and they immediately told me to return the items I was having issues with.
They have been very helpful, and for that I am thrilled.
I did not post about this until after we had the ball rolling to fix the issue.
No reason to bash a company or flat out bitch about things.  Stuff happens, and life goes on.

Nice three day weekend!
Spent most of it attempting to learn how to wake board.
Even though that did NOT go well, I did enjoy being out on the lake.

Rained all day Monday, so spent some time putting the carbs back together.

I need to look in the/a book/manual to find out what jet goes where.
Normally the jets only go in one location, so I never really think about it.
I know I should instantly know what jet is what, but I am lazy.

They came out fairly good.

My hope is one night this week I can wrap up the transmission seals.
After that the bike can start going back together.
Still need to order fork stuff though.
