    That looks really nice, I'll see if I can get some locally. Cheers.

          I'm building up my confidence on this bike a bit now. I think part of it is down to the fact that i put it together, but my ability to chuck it into corners harder has been lacking a little, just part of getting used to a bike but also the bike itself being a bit of an unknown quantity too. Slowly but surely i'm getting there and each time i nibble away at my own envelope the bike doesn't disappoint. It could do with 20hp more, sure, an extra gear would be nice too, but it's got enough there to keep me entertained, in town and blasting around roundabouts it's a hoot.

          In short, i'm really getting into it.

          The engine painting is getting there too, bit by bit, this is that PJ1 mentioned earlier.


          However, in other news, my £7 off ebay, deeply dubious fittings bar end mirrors are now on and finally they don't flop about like a drunks penis, not that I'm an expert on such things.... The initial fittings just couldn't get any purchase on the insides of the bars, the'd fall out given a couple of miles riding, I'm sure. I got a couple of M8 CSK stainless bolts for the centres as the ones that they came with were chromed and undoubtedly the cheapest finish ever, then actually fitted them into the bars with some M8 rawlbolts, which not only means I can tighten them up properly, but also might act as a sort of bar end weight as they're fairly chunky. They don't look too bad though now they're on, and crucially, in comparison to the other more conventionally fitted mirrors, i can actually use these. The old ones, as they fitted on the lever mounts, needed the levers to be more or less flat for them to be within the scope of the mirrors adjustment, while I prefer my levers at about 30 degrees downwards. With these bar end ones on I can have the mirrors in a useful place and have the levers where they feel more natural too.


          I've also found that this bike likes to pop and fart on the over-run, the tickover's a bit lumpy too and it has a real dead spot at what I guess is about 1400rpm, it really stumbles when the throttle's initially opened, then clears its throat and perks up, so I thought I should at least make sure the carbs are in some semblance of order.

          First step was to get rid of the fairly short hose from the tank to the tap, in favour of a cunning 'too big a hose for the job' technique. This bit of hose loops around just behind the rear cylinder slightly and enables me to lift the tank off without actually splitting apart the fuel system. I can actually put the tank itself on a table and have the bike running alongside it, which helps enormously. Interestingly, I found a fair sized lump of congealed silicone spooge in the banjo that the fuel goes through, obviously not enough to cause an issue getting fuel in and out, but when you consider the whole of the bottom of the tank's been off, it makes you wonder where these bits get to.

          Then with the tank off the bike, I balanced the carbs, which were slightly out but not by much really, then adjusted up the pilot air screws, I found that just under 2 turns out was optimal. I then spotted, while trying to put the balancing bungs back into the heads, that the one clamp on the rubber between the carb and the head was loose, so I nipped that up and had a look at the balancing again. This had hardly altered, so I don't think it was significantly loose in terms of the carb sealing against the rubber, which is fairly new. The tickover's a fair bit smoother, but it still pops on the over-run slightly, especially when there's a bit of choke on. As it was raining heavily the day I did this work (ah, the english summer time, eh?) I decided to call it a day and try tomorrow.
          So, rain finished, carbs balanced, inlet boot tightened, let's see how it goes, eh? Well, it's a fucker to start, which is a bit disappointing. I turned it over a fair bit but it still wasn't having it at all, then I remembered that it never starts with the throttle open when it's cold, it's always a 'hands away from the twist grip' type affair. So, half a turn back on the idle speed, starts first time. I guess me tweaking the balance meant that one of the butterflies was previously closed, which gave it enough vacuum to start (it always chimed in on one for about the first 2 seconds, which figures), was now open slightly. This time it starts on 2 with a cacophony of choke induced high revs. After a second or two of that I back the choke down to half way, it idles beautifully considering it's cold, so I knock the choke off altogether and although it really struggles, it doesn't die, which is something. I don't know what it is, but it's something, I'm certain of that.

          Once it's warmed up and we're out on the open road, I wind it on. Instantly there, no hesitation, no clearing it's throat, just there, right away. I also saw one of those honda X11's and was reminded that they're really rare for a reason. What an ugly bike. It's also got a shit load more go than this little bros, I bet: The balancing of the carbs, the tweaking of the pilot screws mean nothing if I've only got 50ish HP and he's got 2.4 times that. Ah well, at least mine doesn't look like it's made in a shed. Oh, right, well... So anyway, it runs really nicely once it's fully up to temperature, no coughs, no pops, no farts, nothing of any note, just smooth transitions from open to closed throttle and back again. Generally speaking I'm quite pleased with how it's fuelling, so why did I dig out that second pair of carbs from under the bench, the ones with the slightly bigger bore?

          Finally, as it all went back together I've come to the conclusion that I'm just about happy with what's going on with the carbs, and hence it's time to put the side covers on too. It neatens it all up a bit, I think.

              You're right, the tail's a touch too broad for the bike as a whole, which is the reason why I've not shown you a photo of it from behind yet! That said, it's a great place to store all of the electrics, I've used the stock seat catch, albeit slightly enlarged where the pin sits in, to take the catch on the bottom of the ducati seat, then with my sneaky hidden cable (I should actually find a place to fit the OE seat lock) the whole thing unlocks and hinges up from just behind the tank, so you can get to all the electrics, the battery etc. I've also fastened the cables for the tail lights to the underside of the seat, so they come up with it too.
              That's a whole load of food for thought with the carbs too, do they fit into the stock brackets and linkages etc or is there a bit more to it than that?

                Naaah,just take 2 masters from 2 bank of carbs and run them with a dbl throttle like flatslides.I had 2 sets....one Crash set up with block-off plates and jetting and a set of spares I put together.
                I spent about $400 for the parts.Poor mans Flatslide.Built Engines only.You need to have at least 75 hp with stock carbs before going that way. I had them at Hords and we did back to back
                dyno runs....1/2/3/ jet changes on the Duhawki engine with them.Impressive....but I ran out of jetting. at 172/168 and lean/80.7hp...then Hord said "buy my carbs" So I did.FCR39's all kitted and perfectly jetted.Then we got 84.7 on 87 unleaded.His 89.1 hp dyno run must have had all the stops pulled....timing...jet fuel....temperature and time of day.....

                  Well, with the work I plan on doing I'd be very surprised if I got into the top half of the 60's at the wheel, it's never going north of 75.


                  Until this turbo gets fitted*....

                      My car's already got a supercharger on it, then if the bike'll have a turbo I'll need maybe a nitrous jetski or something, just so I've got the set!
