Kev, I know you are across the pond but I made a tool just the other day on the advice from another inmate who did the same. Not sure how sizes run in he UK but I used a 12" piece of galvanized 1 1/4" (1.66" OD X 1.40" ID) pipe that I found at a local hardware store for about $11. Basically all you need to do is mark the ends of the pipe at the 12, 3, 6 and 9 o'clock positions as that is where the cutouts are in the nut. I made the protruding members about 1/4" tall and about 4.8 mm wide. This will slide right down over the fork tube and lock nicely into the nut. I used a monkey wrench on the pipe tool I made and viola! No problems! See photo below and please don't mind my cobbling skills as they need some polishing.



Hope that helps!

Shoot Kev, I got so tied up with the tool I completely forgot to look at the springs. When I got my '73 Eldorado it came with what I am assuming are the factory springs installed in the front forks. The guys I bought the bike from was a pretty big dude and he gave me a new set of what he said were progressive springs. I don't know if they were the same spec. but I can give you dimensions on both.

"Factory" springs...or at least what was in there when I took them apart. These look like they have been in there for a LONNNG time!





They look to be about 8 7/8" long

New springs are just a bit longer at about 9 1/16"





I would assume that the difference in spring length is due to the age and sag but there is no way to know for sure. I did also check the spring diameter and it seems the same to me so who knows. Hope this helps!

That is a great help thanks.

My springs are 230mm or 9" imperial old school inches so are still within spec I would assume.
I shall go tube hunting tomorrow.

I now have my fork seal tool in from the US, so tell me is there anything I need to know before trying to undo the seal holders, reverse thread, thread lock, any other surprises?

Ok then I had my fork seal holders off today, and I found that I need to change the bushes on the L/H fork, now on reading Gregory's site it says a special tool is needed, but what is this tool?

When you guys have rebuilt your forks, what grease did you use on the springs when you stuck it all back together?

I just use regular old (amber colored) wheel bearing grease.

Responded to your PM regarding the bushings, hope it helps.

Well my bike is now all back together again, and ready to be ridden, the old bushes were steel and the new ones bronze, I only replaced the upper bushes as I was told the lower small bushes are no longer available. the front suspension is now a lot tighter
Thanks for all the help and advice offered.

Good to hear.

MG Cycle has the lower bushings, their source is likely Stucchi or someone else in Europe.

Been out on my Guzzi today, and something is not right, it is still leaking oil on the R/H side, I think it is coming from the Distributor? but may be from the r/h head to barrel joint?
Also the motor is running very rough/lumpy, unless it gets loads of revs then it smoothes out, could this be the big ends going or something else.

As it was a nice sunny warm day, and as I have the forks back together, I though I would take the Guzzi out for a spin around the lanes. I have not had a chance to ride it since changing out the barrels and pistons, so it really needs some miles under its wheels if I am going to start using it for camps up and down the country.

I got caught again at the swing bridge as a canal boat went through, good opportunity to grab a couple of pictures





I then carried on through the lanes, and also a couple of the bigger roads where I was able to open it up a bit, but all is not well in Guzzi land, as the motor feels very lumpy, unless when the throttle is opened up a bit, so fearing the worst I headed home, and left the bike to cool down. I also noticed another oil leak, this time on the right hand side, which appears to be from the distributor shaft.

So after the bike had cooled down a tad, I decided to pull the dizzy to fix the oil leak, and I thought it best to re torque the heads after the barrel swap. Now considering I had done very few miles, the oil was in a terrible state, so I thought I would drop the sump (first time since I got the bike) and have a look in there

Not a pretty sight!







Now one things for sure, it is not chrome, as it is all magnetic, and rusty? any ideas?

I had a good look around the bottom of the block, and all looked fine in there, I checked the con rods for play, there was no noticable up and down play, but a bit of lateral left to right play along the crankshaft, this was the same for both rods, so I am guessing this is OK.

I would like to pull the heads, but if I do I won't be able to try the bike, until I can get another head or thread repair for the right hand exhaust nut.

Charlie I could not find any identifying marks on the head?

Can't say what the gunk in the pan is but as advice to any new Loopframe Guzzi owner....first thing you should do is pull the pan and give it a good cleaning!

People are getting tired of me posting the same old mantra.
It goes for ANY bike. Especially for bikes with no oil filters!
Drain, Drop and Inspect the contents of the pan! First thing!
That's history in there.

A lot of history. Looks like the pan hasn't been dropped for a good long time.
Are they big individual chunks? Or globules of assimilated material?
Big shiny chunks are bad.
Clean that mess up. Save it.
Change oil.
Put in a magnetic plug.
Drop the pan again in 600 kms.
Check for excessive accumulation of frass...
Ride.

wish I had something more to add but agree with danedg. I am assuming that the "lumpy" running of the motor is just that and not a knocking coming from the bottom end? Do you know for sure that you have good solid oil pressure? Easy to check by threading a gauge in the block where the sending unit goes. Heck, I am going to follow Gregory's advice and fit one to mine full time...let us know what you find out!
