Do you have an H shaped piece in the pile of parts? You will need that part to attach the stock front fairing and if you do have one it would be wise to weld up a new stronger piece because mine would break after a few years of use. And if you do go with LM I front fairing you will need to open up the cut outs for the wider forks on the CX. I’ve never got the fairing to sit the same way as a the one on my Lemans I but when I can locate the LM I left headlight bracket it might solve the problem.

I have that bracket.  Where does it break?

Thanks but it looks better in the photo than in person. I recently had the frame powder coated and a new wiring harness installed but the tank,fenders and side panels all need new paint as it’s been at least 15-20 years since they have been painted and it was used as a commuter for many years.

It does look good in the photo and my guess is pretty good in person even if it is a bit worn.  I always like a bike that looks like it gets used over one that is just for show.  What dash is that?

From memory it usually snapped at the bolt holes. The dash is for a 850T3,etc.  https://www.mgcycle.com/index.php?main_page=product_info&cPath=276&products_id=4480

Good luck on your project. I've enjoyed this one for 35 years :thumb:

 I'll bet that's a whole different front end -  triples, tubes, axle, and of course wheel.

Any updates on your bike?

No updates yet.  This is one of those projects that just fell into my lap.  I need to finish up my BMW R65LS plus some other small non motorcycle projects before I start really tearing into it.

I am more convinced though that this bike really does have only 25 miles on it.  Nothing shows any signs of wear, no stone chips. foot peg rubber perfect, no carbon buildup in the exhaust etc.  Talking a bit more to the original owner's daughter she only remembers this bike coming home then being taken apart.  Her Dad had other completed bikes though, all modified.  Sadly this project stalled when his friend who he worked on all this with passed away.  This Guzzi has been just sitting in the garage for 40 years before I wheeled it over into my garage.

So much of the bike has been modified though that even if I put it back to stock I would never suggest that it is an original CX100 with 25 miles on it.  Kind of the Ship of Theseus problem.  I am also the type of person who believes things should be used and well cared for rather than just sit as a static display. 

Wish I could find some more info about the front end, it's cool and the fabrication looks quality but I don't know if this setup has been tested on another Guzzi before or it's a one off that has never seen use.  The brakes were also delinked with a different master cylinder setup on the rear but still with the stock one up front.

Once I really get rolling on this project I will start a thread in the Bike Builds section of the forum.

The R65LS was a bigger hit with journalists than buyers, and did not stay in production for long. Today, like with most bikes that were slow selling when new, it is the 650 BMW people want. Is your red or silver?

Mine is silver.  I wanted one ever since I saw them when new.  A nice survivor with 23K miles that got regular oil changes but nothing else.  I mean it even had brake hoses date coded 1981.  So I have been going through it and refreshing/rebuilding what needs to be and doing the bigger maintenance items.  Surprised it ran as well as it did when I got it considering how much rust and crud was in the tank.  Goal is to just make it a nice rider and enjoy.
