Thanks WhitePaso, secretly I think the LTD was just a marketing idea, (some would call it a scam) but I'm open any knowledge available on this..
I have been told they have hot cams and big valves, which is all very well but people don't always want to drive their bikes between 6 & 8K RPM all the time, riding "way up there" is downright dangerous.. Although in saying that while on a ride last week the Paso performed amazing at the top end, I went up to 115mph in a snap, everything felt happy as up there. I'm struggling with flatness in the 2 to 5K range,
This Paso, Pantah engine & Mikuni carbs are new to me and learning curve, all my past Ducati experience comes from a bevel drive,
I "spat the dummy" with the whole thing last week, I went for a ride and when coming up to an intersection it coughed and stalled,, I wasn't slipping the clutch, it lurched forward, I lost my footing on some loose metal and over we went.
The bike rolled onto a curb, scratched and broke some fibreglass on the left side, as well as the left indicator mirror.. It took a bystander help to pick the bike back up as petrol poured out of the overflows and made the road so slippery I couldn't lift it by myself..
I was going to go down the back country road twisties for the next hour in the afternoon sun, but instead had a very grumpy plonk home on the motorway.
Pissed off, I put the Paso into the back room and shut the door for a week...
A week later.... Being a happy Ducatisti, I soon got all that behind me and got on with the business of turning myself into an A1 mechanic ..
A weeks worth of research and thinking, watching the summer slipping away and I'm happily back on the case.
I pulled the carbs apart and cleaned everything putting it back together, I fixed a range of issues re-routing the fuel line to reduce the pressure, and shifting the needles to the top position after a few days I've got it to run quite nicely.
Written on the side of the carb and barely legible is DUC75 T1 Y1, from what I've read on this site thats should be used for racing and should be changed, but that is yet to happen and I need to understand more before they get changed.
One of the gems I found on this site is those tubes coming out near the top of the carb, one pointing backward the other pointing down, these are the breathers for the bowls and need to have tubes on them leading to a pressure free place, I made mine the same length (about 800mm), put some insulation (plastic wool) in the ends to stop dirt getting in and ran them along under the seat. Those two "vents" had been bugging me for ages as it was obvious the pressures would be different but I had no idea what they did.
Some of the tools I used might be helpful to others,
I made 3 lines for the overflows one from each carb and one for the T between them. On the end of the lines I placed small plastic pill bottles, this allowed me to see any fuel and which outlet it came from, this system really works as I started with an overpressuried pump (solved using a by pass) and one carb got some grit in it, (from the by pass) then flooded, it was all easy to see where the fuel was coming from.. and these can stay to be checked if I feel the need.

A useful tool I created for balancing might be of interest to others, it's cheap and accurate
get 2 big glass bottles, 2 plastic caps with 2 holes in them for plastic tube, build it so there is long tube to transfer the water between the bottles, this joins the bottles together so when vacuum is applied to bottles water flows one way or the other, coil the tube inside the bottles ..
the other tubes connect the manifolds one to each bottle.

add water (make sure you don't fill more than a third of a bottle, if you put too much water in there is the danger of sucking water into the engine)
put a light behind it if you want to get sophisticated or stylish
Start the engine and set to a fast idle, you want to balance at 3500 - 4000 rpm, watch whats going on, the water will pass from one bottle to the other, when you tweak the carb adjustment the water will slow, speed up or reverse flow. I found the most precise adjustment was obtained by letting the water run from one bottle and fill the transfer tube with bubbles, by watching the movement of the bubbles in the tube the adjustment was really sensitive but accurate.. (rather than the water levels inside the bottles)
The adjustment difference would have been 1/8 of a turn (if that) between the bubbles going one way, stopping then flowing back, play with this for a while and you will realise how accurate a technique this is ...
