  1. progress update: decided to order myself a set of custom yokes instead of messing about trying to make things fit. They took 10 weeks to arrive, but they were worth the wait. Very impressed. The fit of the ignition barrel is absolutely perfect, it even includes the fittings for the transponder ring that sits on top of it. very happy Stuck it in the freezer overnight, and fitted the bottom bearing: Trial fit up: fitted to the bike: I need to do some more work on that airscoop, but that can happen later.
  2. yes! thats kind of what I was going for. big aggressive airscoops
  3. not done a great deal on the bike itself, but i have done a fair bit of 3d modelling. i was reasonable happy with the radiator side panel, its done apart from a few little tweaks. the next job was building some airscoops to fill the huge hole under the fuel tank. To do this I have had to learn about forms with fusion 360 (previously i have just modelled solids) Forms are a lot more fluid, and used when you dont have any specific straight edges/dimensions you can put a ruler against. So. to do this I first needed to define the contact edges of the of the tank and the frame where the airscoop will sit. In the abscence of a £10,000 3d scanner I used a technique called photogrammetry, where you take a load of photos of the object you want to scan from all avaiable angles, then you feed them into some software and it creates a 3d image of the bike that you can play with. Here are the results: from there i stripped away the unnecesary parts and left the surfaces I need for the airscoop, which is the top rail of the frame and the bottom lip of the tank. Then I exported it as a dense point cloud into fusion 360. In fusion 360 I could then plot a T spline curve alone those edges which defined the edges of the airscoop. I then mucked about with surfaces in forms until I got this: This was the first printered iteration, I am on verion 4 or 5 now, and it looks something like this: Couple of flat spots on here I need to sort out on the next print. how it hangs together with the radiator in place: over all I am quite pleased with hows its going, not finished yet, but it should look fairly factory (ie not nailed together in a shed) once its done.
  4. much appreciated. is that an US site or can you order from the UK?
  5. does anyone know where I can get some new exhaust studs and nuts?
  6. been playing with adding some detail to the panel:
  7. sorry guys, been a long time since I posted anything up on here. this is the current status in pictures: chopped all the brackets out, plated and welded the fuel tank: I then lead loaded it, and its currently ready for a final skim of filler and then paint. I reckon i might have gained about 400ml in fuel capacity. that might have to do for now. 180miles is fine for a tank range for me. 200 would be better but i am not crying about it. I also ditched the 2 fillet pieces I was going to weld on as I couldnt get the shape of the tank to fit with the frame properly. made the front bracket for the fuel tank: few other little bits (earth point etc) did some more track days on the TRX: Decided to reuse the stock airbox, but open it up a touch. First pass at making the ignition mount, this wasnt so easy. radiator mounted: its a bit wide. I have looked at using a twin radiator setup from an aprilia mille, and it is narrower, however I have decided to stick the original radiator and try and make it fit. headlight mount: trial fitting the clocks: I dont like the stock clocks but as Ken has mentioned you have to use them because of the unique serial protocol that the bike employs. so with that in mind I have decided to make my own surround for them. I have a load of other fairing panels and fittings to make so I decided to get into 3d printing. so far I have done 5 iterations of a left hand radiator panel, its getting there: verision 1.0 this was version 4.0: its a bit bulky, version 5.0 is coming out the printer as i type and is going back to a slimmer version (current build time is 1 day 10 hours per panel) so thats basically where I am up to. Ive not had much time on the bike this year which is dissapointing. Im hoping to get back into it shortly.
  8. wow. thats good news for crosstourer owners, upgrade headers and remap and bosh massive power increase! does the crosstourer have much more low down torque? in reality all these detuned engines just seem to be completely neutered in all areas.
  9. eh?! surely not! so an exhaust change, and ecu flash and you go from 127bhp to 170?! seems like a massive leap in performance.
  10. had a fairly productive afternoon yesterday. I managed to get a load of jobs ticked off my list. one of them being a bracing around the headstock -pics: I then realised I was nearly at the point where I could stand the bike on its wheels, so i quickly fitted the forks and built the thing back up: This has been a big motivational boost for me as its turning out exactly as I planned. really keen to get cracking with it now. I can see this 2 to 3 year project being roadworthy by August.
  11. IWorking from home 3 days a week. its amazing how much you can get done at home compared to in the office. no commute either so i am ending up with a bit extra time on my hands. Managed to get a few more bits ticked off over the weekend: Rear tank mount https://i.imgur.com /em5N80F.jpg[/img] Needs the welding finishing and dressing up with some radius ends, but it does the job. its probably the heaviest duty tank mount that ever existed! Sticking with the tank I decided to make a start on the modifiations to the tank itself. I bought a fuel tank from a fazer 1000 thinking it might fit quite nicely - it didnt. So I decided to use the fazer tank to make some extensions to the vfr tank. With my bike not having any bodywork the front of the tank looks a little 'pointy and unfinished. So I have made a start on this: The inital effort was just too wide for my liking, so I slowly cut away until I had something that I think might work. The lines of the tank now follow the frame spars quite well. Thats as far as I got. its a slow process
  12. Sidestand build: Thats in the same position as it is on the original bike. In the folded up position it does look a little lost now there is no big meaty aluminium frame back there but theres not much I can do about that at the moment. I was talked out of using 12mm steel plate to make this up and went for 6mm. I just shudder when I think of the amount of weight pressing on it, especially when you do that balance on the sidestand trick to spin the bike round. for my pease of mine I am going to fit some webbing on it to give it some lateral support. Radiator mounts next
  13. update. back end is done and tacked in place:
  14. update in pictures: selling the ohlins, wood is the new gold!
