The Mega Paso Project

[Desmo_Demon]

Since it appears I have completed my first Paso project, a functional restoration of a sorely abused 750 ( http://www.desmodemon.com/vicks_paso.html ), I am now ready to start on my next project. I will call this one the "Mega Paso".



Here is a page that I have started for this project:
http://www.desmodemon.com/mega_paso/

Through the restoration of the first Paso, I have accummulated various parts, and I have had the thoughts of building another Paso, a custom Paso, from some of these parts. I have shared some of my thoughts with Gerhard (paso750) over the last year about this project, but I am now ready to attempt to piece these parts together. Here are the specifications of the parts that I will attempt put together over the next few months (years?):

Frame:
1988 Ducati Paso 750

Engine:
1999 Ducati ST4 916
liquid-cooled
104-bhp

Electrical:
stock 1999 ST4 wiring harness with factory ECU

Front Suspension:
1994 Ducati SS900cr SHOWA USD forks with SS900 triple clamps

Rear Suspension:
Stock Paso shock and linkage connected to a modified ST4 steel swingarm

Wheels and tires:
front - 17" Brembo three-spoke from a '94 SS900 with 120/70-17 tire
rear - 17" Brembo three-spoke from a '99 ST4 with a 180/55-17 tire

Brakes:
front - 4-piston Brembo calipers with full-floating 320mm, cast-iron rotors from a '94 SS900
rear - 2-piston Brembo caliper and rotor from a '94 SS900


I'll update this thread and the website as I progress on the project......Wish me luck!!!!

I "wish luck" to You and as You know, we try to help You, as we can....

I am remembering, that someone tried to fit 888/851 engine to 906 Paso frame, so it "can be done", but surely it needs plenty of time... I pray, that you have just that time... Unfortunately i dont have... I have also one dream to add my spare 907 engine to my 750 Paso frame one day.... But other way i really want to keep my 750 still as original, as it is possible still....

btw, do you try to register that bike to street use, or only to race track????

With the titled frame, I have all the paperwork necessary to put the bike on the street....if I ever complete it.

Here are some pictures that Gerhard posted a while back of a Paso with an 888 engine.

That`s Boz` bike.

Terry, don`t complain in future that you have so much work with your bikes
This is a big project.

here the pics of the frame that was on ebay longer time ago



There`s a german guy with a 907ie with a ST3 engine.
If you can drive a car in the US that has the shape of a shoe I`m sure this will be street legal also

Wouldn`t it be easier to use your 907ie swingarm ?
Btw congratulations to your first project it is on range 2 of the most read posts

It's easier to fit the 851/888 engine on the Paso frame, rather than the ST4 engine, because the shape of the 916 engine is different.
I guess you have to do a little modify to the engine to fit it in the frame.
I'd prefer to do a modification on the engine rather than a modification on the frame.
Best wishes .

I can see where the Italians got their inspiration, it looks like a bowl of spaghetti

Good luck with the project, Its a credit to you to take something like this on in the first place and then especially to take the time to post it on the forum. By the way, congratulations on your other resto, that was a great read.

Probably not. The swingarm mounting bosses on the ST4 engine are too wide and would need to be machined.

Yes, the mounting points of the ST4 engine are wider than the Pantah engine by 2-7mm on each side. I will have to trim them back to mount into the frame. I don't know if I'll run into any other problems with it, yet. By triming the mounting points of the engine, if this project doesn't work and I ever destroy the engine in my ST2, I can add spacers and put this engine in my ST2.

when making the engine mounts be very careful. I think it`s one of the difficult things, to keep the front sprocket in perfect line to the rear one.

Not an issue with the ST4 engine and the modified swingarm, as the swingarm mounts directly to the engine and is aligned by design. There are shim washers on the pivot pin to get the proper side-to-side play, though. Also, for front wheel to rear wheel alignment, I will be taking the dimensions of each individual engine mounting point from the mating point of both engine cases and duplicating the measurements from the Pantah engine in the running Paso 750. Naturally, I'll doublecheck everything before I even make the first cut.

Not sure if that offended, hope not, but looking at it, the hoses, lines, wires running everywhere reminded me of one and I thought that was humerous, maybe not

I just added a few more things to the webpage. You can now scroll to the bottom of that page and be directed to pages about the engine and front and rear suspensions for the bike. The only page that really has anything on it is the one for the rear suspension. I had the swingarm modified a couple of weeks ago and finally got around to painting it and taking a few pictures of it.

Ok we'll send you some sample of "real italian smoking spaghetti dish " to let you have a better idea about!

Yes, that's a good idea my wife and I love pasta. I think this thread will be very educational and in more ways than one, could you also send the recipe?

[persempre907]

could you also send the recipe?

I don't believe: the good cooking is always a secret
