Firstly thanks God you are safe and sound!!!
Secondly awesome job done!Gongratullations for both of you for your patience and insistence!Really nice result!I wish you plesant and adventurous km with your bike always drive safe!As I mentioned before this must be a sticky thread and could easily become a nice "how to" for everyone who would like to rebuild his peg!
Big job, nice capture, well done.
And looks like it was fun.
great report and man you went to town on itwell done
you are only as young as you feel
Here are my additions to what my brother posted:
Removing the old steering bearing races from the frame is easy. With a suitably long punch, drive the outer races out of the frame by slowly hammering at different places around the race. Do not simply hammer in one place as the race will twist and expand/oval out the frame. Working around the edges of the race helps keep the race somewhat straight as it comes out. Just for information, the races have an outside diameter of 52mm.
The real challenge is removing the lower bearing from the steering stem. In this picture, the old bottom bearing is all broken.It was not like that in the bike. My first attempt at removing the bearing involved cutting the bearing cage and removing the roller to expose the upper edge of the inner race. I attempted to use a bearing removal clamp to hold the inner race and drive it out with a hydraulic press. Unfortunately, the race edge cracked as can be seen in the picture. Eventually, I simply pressed the steering stem out of the lower triple clamp, taking the bearing off along with it. My goal was to save the lower seal, which I was successful. Then I simply pressed the steering stem back into the forged aluminum lower triple clamp and then pressed the new bearing into place. For all of this, I used the hydraulic press over at our good friend’s shop, Rallispec. http://www.rallispec.com/Originally Posted by '74Stratos
Look at the difference!
I could not have done it so cleanly (or maybe even at all) without access to his equipment.
After seeing just how bad the steering bearing were on ‘74Stratos’ Pegaso, I want to replace them on my Pegaso soon. This is why I went thru the effort to make a fancier installation tool than bare minimum; make my life easier later. I made the tool similar to the ones I used decades ago when I was a bicycle mechanic, just larger. I used a ¾” fine thread rod, two nuts and two dies.The dies began life as 2” (50.8mm) diameter, ½” (12.5mm)thick steel rounds which I bored a ¾” hole in the middle and turned on lathe a 16 degree tapered seat, leaving a rim on the end. The races have a 15 degree surface for the roller bearing so I cut the taper to 16 degrees so as to ensure not contacting and scoring the brand new surface. The rim would apply the force to drive the race in. Honestly, the taper was not needed but I wanted to make sure the tool self-aligned itself. In the event that the races recess into the frame (they don’t but I had not taken notice before removing the old ones) and the tool misaligned, the races would not have been fully seated. The tool also ensures that the races are pressed in evenly and parallel as driving them in with a hammer may result in crooked bearing and lead to handling issues or loose bearings.Andysrage made a bearing race press to install the races into the frame.
The new bearings were packed in NEO HP800 high temperature 800F(425C) synthetic grease. Since the frame acts as the engine oil tank, the steering get very hot, causing cheaper or low temp grease to melt and run out.
On the maiden ride, the bike ran fantastic while quieter and more solid feeling than my Pegaso. Makes me want to rebuild mine this winter! Best part, not a single leak. It was a fun project and the results make it feel very satisfying. After several years of not riding, I'm glad to have helped my brother get on the road again and ensure his bike is 100% functional & safe. Now he can focus on havng fun.

Very good job boyz!
Hope to get ready with my jigsaw-Peg this autumn/winter.
I grab yesterday evening my BST33-Carb to put it today at work in an ultrasonic bath .... then replace some gaskets etc....
Ciao,
Holger
Any news?

Speaking for '74stratos, the bike seems to be running great although his schedule has limited the number of rides he has been able to take on it. I think there was one ride were the bike stalled once on him. It started right back up and hasn't had any issue since. Maybe it is time to install the iridium spark plugs I have. I didn't install it when we did the rebuild because I wanted to clear the engine of all excess oil in the cylinder and not risk fouling an expensive plug.

In addition to andysrage's comments, I can say that my bike has been running quite well and makes good power, especially up top. If rushed, it will pull to the "indicated" ton without hesitation.
Even so, I am experiencing the well-documented lurchiness between 3rd and 4th gear, especially at lower rpms. That being the case, my future plans would be to install the Factory Pro CRB-AP65-1.1-ti jet kit and new needle jets (emulsion tubes). I would also like to test the rectifier, to ensure that it is not playing games as well. Hopefully we will have time to address these issues over the winter and see if it smoothes out the power delivery in the lower range.
Right now, my focus in on purchasing more comprehensive all-season riding gear. So the modifications will have to wait.
¡Ráfagas!
Hi I would like to ask you a question about the dial adjustable levers you installed.
Where did you buy them and yow much did they cost?
Could you send me a link?
Thanks in advance!
Up...Does anybody know where I can buy those adjustable levers you used on the project for my pegaso?
thanks in advance!
It is said that Ducati Monster, prior to 2000., will fit the brake side.

I do not know of the clutch side, as it is cable operated.
(that might be Magura brand).
We got the pair of adjustable levers for the BMW F650 Funduro from Wunderlich: http://www.wunderlich.de/Shop/F650-S...omfort/Griffe/ or http://www.wunderlichamerica.com/mot...60121-123.html
They are standard Domino parts. If I knew what model bike these came originally from, I am sure they would cost a fraction of the price. What you are really paying for is the fact that someone else did the research.

Thank you very much!
... and there we were...
... stranded by the side of the road yesterday after riding approximately 100 miles in 85 degree heat at sustained high speeds. Yup, the dreaded Regulator/Rectifier ("Rectum fire") failure has hit the Blue Peg
It's amazing how sh** happens at the worst possible time.... and there we were...

I was looking for one for my brother's Peg......

You can go with the one that has 2xred and 2xgrn wires as well.
