The Mega Paso Project

Will it be 16 or 17" frontwheel?

I will try to use a 17" wheel from a '94 SS900 as long as it doesn't interfer with the horizontal head of the engine. I didn't have a tire on the SS900 wheel, so I installed the 16" wheel, so I can roll the assembly around. I may mount a used front tire on the SS900 wheel, the next time I change a front tire on another bike.

I'm not too sure how I want to check for the wheel/head clearance. I figure I can either secure the chassis and pull the front end down with straps until it hits the head or stops, or I can remove the top caps to allow the springs to come out the top, and then see how much fork travel is required to have the wheel hit the head, and compare that distance with the allowable fork travel of the forks.

I figure the worse situation to make the arrangment work (if the wheel hits the head) is to probably use a combination of a stiffer set of springs and a physical stop to reduce the total distance of fork travel. I don't recall ever bottoming out the forks on any of my bikes....at least on the street, and I sure don't want to do it if it results in the wheel stopping its rotation.

On the ride home from work, yesterday, I rolled the 2000-mile mark since getting the little Paso back on the road (my regular Paso, not this MegaPaso project). In just a hair under a year, I've only logged 2000 miles on it, but it is not one of my main rides. Surprisingly, I think I've almost put half of those miles on the bike while in the mountain twisties (it's a fun bike). In the last year, I've only had a centerstand spring brake and had the mirror fall out of the mirror housing. I did have to replace the bronze button and throw-out bearing in the clutch, but those were bad before I got it back on the road.

I'm hoping to log a few thousand more miles on this bike without having to do much to it. I figure once I put 5000 miles on it, I'll be happy and content with the purchase and my time rebuilding it......I just hope nothing major goes wrong in the next 3000 miles.

I can only imagine what this MegaPaso will be like if I ever get it together and operational.

We also hope that

Nice work, should be interesting to ride !!!

It's hard to believe that it's been about two years since I have last touched this project. I am done with my master's degree, though. That was the main thing keeping me from working on this, well, that and everything else seeming to need work/repairs.

I have a guy lined up to reweld the section of frame I had to cut to clear the horizontal cylinder head, and I need to get it over to him before he retracts his offer (made nearly a year ago). I've also been thinking about the gas tank hitting the vertical head and the cooling/radiator concern. I believe that since the tank that I have is severely rusted, I may cut the whole bottom out of it and build or find a fuel cell that will fit under the outer tank shell. It'll be a similar arrangement to the Bimota DB2. If I make a fuel cell, I can shape it any way I want and have the bottom shaped so I can use a Ducati fuel pump assembly for this fuel injected engine. I'm still thinking that the cooling will need to be done with a split radiator setup, like most dirt bikes. I don't know if I'll be able to find an existing set of radiators that will work or if I'll need to have two custom made (I don't like the idea of what that will cost).

I've got a couple of weeks off in December for vacation, so maybe I'll try to work on this project again. If I can just get the frame welded, I can bolt in the engine and start assembling the bike. In January, I'm supposed to start some online teaching for a technical college in addition to my regular 40+ hour a week job.

Why do you think you need two radiators?

The 3-Valve-Engine in my 907 works fine with the 907 radiator & the ST3 Oil-Cooler.
Downtown & on the track.

It ist a very interesting project ongoing in your garage :-)
This is what i wanted to do first, but it was too complicated for me. Thats why i chase the 3-Valve engine.

/edit: i think i know now. Because there is no space between the forward cylinderhead & the wheel, right?

...that and everything else seeming to need work/repairs.

And new bikes that needed to be bought

Dual radiators are mounted on the side so there`s not the problem that the wheel hits it under hard braking.
Is there a difference between a water an an oil cooler ? Can`t you just take some from a P750, flush them and change the connections so you can use them ?

And new bikes that needed to be bought

Another one that required work, of course. BTW, I had to have a front sprocket machined. I wish I could find some spare retainers, because they would work quite well for the Paso sprocket shimming project (about 3.5-4.0 mm offset).

Exactly!

I have very seriously considered this and was guessing that about the only modification that may need to be done is larger inlet and outlet for the radiator hoses. To also aid in cooling, I've been thinking of adding an oil cooler, like one of the newer designs that mounts down low in the V-panel area under the horizontal head and not in front of the engine...
