Re: HELP NEEDED Regulator Wires Brown & Pink

I have a Kawasaki rectifier here and I'll explain the wiring connections. First, the red wire from the alternator is 12v and although this could be used for power I found this was heating the lead from the alternator (not good) so I've connected it to the blue from the instrument panel and this is n...

Re: HELP NEEDED Regulator Wires Brown & Pink

The Paso charge system is a funny one. The 2 pink wires are AC and must be rectified. The red wire from the 'alternator' is 12v and goes to the charge circuit. The 12v output from the rectifier goes to the coil feed. I can pull my Paso panels off and double check this but when I used the Energis rec...

Re: Rear shock options

I never thought the original Marzocchi rear was any good. I obtained a 750 Paso rear shock and that turned out to be far better. Adjustable preload too! A tight fit but it just about squeezed in, I made a bracket for the hydraulic adjuster and placed it where the damper control used to be.

Re: Weber DCNF fuel pressure issues

A problem to have fixed later is a slight wobble in the front rim. Very annoying around 50Kph and again somewhere between 100 and 140kph. Cheers, william I expect this is due to the steering head angle. If the head angle is too steep the bars will shake. Try and reduce the spring pre-load on the re...

Re: alternative fuel pump

I placed a fuel pressure regulator after the fuel pump and found the changes in air temperature affected power output the greatest. Colder weather meant higher air density & oxygen, so on that day I would increase fuel pressure to the Webber. Just running it with a simple return line to the tank...

Re: engine dropping onto 1 cylinder

I replaced the ignition coils with ones from an Aprilia twin, 5 ohms resistance. I did this after running the Paso at the racetrack and picking up a misfire; due to over-driving the Digiplex. Your cutting out does sound like an electrical problem.

Re: Buying secondhand

Non runners can be almost a basket case but in the case of Ducati they are usually a reasonable project. The only thing that affects an old bike is where it has been kept. Outside? Any motorcycle will only put up with that for a year or two before major damage sets in. If it is actually running with...

Re: Ducati belt engines - a nasty secret flaw?

This was a contentious issue back when the Pantah engines were raced. There were some after-market chain guards available. I made one for my 906 that replaced the plastic sprocket cover. It bolted on to the existing housing but had a steel band welded to the inside of the cover that ran along the ou...

Re: Rear suspension unit

Really total wussies. Funny. Along with Ronald I suppose what I mean is if you have the right tools and can disassemble the shock, then go for it. If not then take it to the specialist - since bike parts are so minutely machined and delicate that one slip can result in a breakage or that its so mar...

Re: Rear suspension unit

Don't be trying to work all this out yourself, find a local suspension specialist and drop it in for service. Motorcycle suspension is difficult to work on without the right tooling.

Re: A thought that came to me

The quality of the motorcycle is almost always reflected in the price. It is rare that you will ever buy a bargain, if it is cheap - expect plenty of work to restore it to a reliable and useful condition. Bikes are fairly easy to assess and it is equally difficult to 'hide' faults if you just test-r...

Re: Replacing the Digiplex S2 on the 906 Paso

Got my new Digiplex in the mail last week. Installed it yesterday, and went for a ride today. I've said this before, change the standard ignition coils to modern units from eg. an Aprilia. The standard coils have a very low impedance (<0.8 Ohm) that causes overheating of the Digiplex. With a high i...

Re: lots of money ? no brains ? ........step right this way

Though it would be nice if once we all bought Paso's they became a sought after forgotten era classic and worth $50k. I think there is every chance that early 'carb machines will climb in value the same as the car market has gone. The modern stuff has any amount of electronic trickery and it is onl...

Re: Paso wheel restoration

He is right about wet weather affecting the wheels. Recently I had a set of new tyres fitted and the shop (run by a friend) told me that minor corrosion on the bead seat had meant the tyre wasn't fully sealed. Happily only a rub-down of the seat was needed, I would have been happier to wait and repa...
