I've read in the TECH FAQ that a fuel pressure regulator would improve the the behaving of the Paso. I already got used to the "behaving" of the Weber Carbs (full open or closed it behaves O.K). But crusing to the city or first gear corners is still difficult beacause a sligth turn at the handbar makes a big effect.
Can anybody tell me wether its worth to invest some time with it, or has anybody exerience with it and can deliver some details? (Other carbs are no option for me)

I have an hand made regulator installed, but I think it only helps to fill the float level after a long time standby...
The real masterpiece of soft riding is the trottle balancing (I have a tuned engine, 2-1 exaust and an hand made muffler) and I can ride without flat lines, backfiring, etc :thumbup:

i would forget about the pressure regulator as there should be a return line to the tank which negates the need for a pressure regulator. the real problem lies with the voltage supply to the coils. if you do a voltage check at the coil supply you will find that the coils only get about 9 volts not 12 which means a huge drop in the voltage arriving at the spark plugs. thus leading to fouled plugs and substandard performance.a relay needs to be installed to deliver battery voltage to the coils. incidently the coils are where battery voltage is sensed which is why the battery can give problems with over charging
i have done this electrical mod and the difference is amazing. no more fouled plugs, no flat spot under 3000rpm, no more over charged battery and easier starting

I think that Chi raises a good point about the feed to the coils , the same should be done for the ignition module , and a decent earth fitted . I had all sorts of problems with mine ( see earlier posts ) untill I did this mod .I later found out that this is why the last owner sold it .I think the main issue is the main power supply wires are to small and fitting relays to the main organs is a good cure as long as there is a power feed direct from the main fuse to each relay . I mucked about with the lenght of the return line to get a suitable fuel pressure I have a rotory type pump and I just lenghtened the return line till I could hear the pump motor just starting to work a bit ..yeah yeah ,I can imagine what your thinking :wacko: but it worked :thumbup:

There are several basic changes that improve our Paso's.
Bauke's Relay bypass for the ignition unit - correct supply voltage to Digiplex & better ignition
Fuel Pump regulator - stops stalling at tickover
Up jet the accelerator pump - smoother throttle response
Check ignition coil impedance - too low and the Digiplex can fail

As has already been said there are many more but patience and a willingness to disassemble pays dividends.
