Spaghetti exhaust headers

Discussion in 'Supersport (1974-2007)' started by MADASL, Mar 27, 2013.

  1. we've had made, in stainless steel, this prototype for a race bike we are preparing and on the back of it taken orders for 3. One for the project bike and two for Louigi Moto.

    It is a copy of a Sil Moto item I have on my race 900ss but with some improvements (lambda sensor bungs, more durable steel etc.)

    To keep costs down I need to place an order for five kits from the tube bender. Any one interested in one of the other two please PM. For this pair only the cost for an exhaust will be £450 plus delivery.

    The final version will come with Lambda boss, spring loops, springs and flanges. The centre section is adjustable to fit the SS and SSie range. With a little fiddle it could also fit a Monster.


    PM me for more information.

  3. Thanks for your constructive comments - of course I did say it was the prototype for a race bike.

    All you have to say if you don't want one is no thanks.

    Regards:upyeah:
     
  4. A prototype (if you are wanting to sell others) should showcase all your skills and be exactly what the finished product will be.

    Otherwise (in this instance) it will be seen as a shoddy back yard conceived idea and ill constructed tat. HTH.

    p.s. don't want one...................OK?


    p.p.s. I recently had a custom made "spaghetti" header done for a cafe racer project 900SS in stainless steel, one off, total of £350. Ten times better than that bodge-a-matic effort.

  5. new ducati

    Ducati show off their latest prototype multistroodle touring bike, with built in entertainment console.

    Production model will feature advanced multi-programmable fuel injection, marchesini forged superlight magnesium wheels, titanium chassis custom built and superior wind tunnel tested aerodynamic carbon fibre bodywork and all new V4 engine and seven speed gearbox, plus a state of the art solid state i-pod sourced mutli channel sound system.

    You can buy this one off pre production prototype version illustrated below for only £55000........... production versions will be cheaper (we hope at around £45000) once we confirm three orders, all paid for in advance. Production versions may not feature the third wheel.

    Thank you.

    Visit www.prototypesR-Us.com payment by paypal please.

  6. As always your opinion and council is appreciated.

    In my humble opinion though you describe a 'first of the line' - not a prototype to check fit but hey semantics.


    My only reply is that I've already sold 3 on the basis of that 'prototype' understanding including two to Rich from Louigi Moto who is putting it one on his own bike.

    You got a good deal at £350 - perhaps you should get a run made also or at least give the forum the details of the people who made it so they can save £100 over what I'm charging :upyeah:

     
  7. I did ask if he was interested in doing more and possibly jigging up, but he said he'd do them as and when, didn't seem to think it was a big deal. If I get chance I'll find a photograph of them.
     
  8. A photo would be great and the details of the fabricator.

    I assume they built yours on the bike which is why there is no jig. The jig was the hard part with the one we made - bloody tubes everywhere!! The next hardest was finding a good tube bender who could do a tight radius without wrinkles in thin walled stainless. Even the Sil Moto version has a wrinkle in the tightest corners!

    Many thanks,

     
  9. Are the headers using 45mm tubing?

    By the way good to see any bits being made for the SS/SL - sure your final headers will look pukka! How do you intend attaching them to the cylinders?? As per standard?

    Cheers Pablo
     
  10. Being slightly old fashioned the tube is 1.75 inch - or 44 and a lot mm!

    Attachment will be using a sleeve and springs - I just like the look of springs on an exhaust - is it just me?

    Thanks for your interest - Velocity stacks coming soon also for the ie bikes.

     
  11. The "first" of anything needs to be scratch built. Jigs are built really for the construction run after the initial "jobby" is proved to be correct.

    Many years ago when I did a lot of white water kayaking, we made our own boats from a mould we constructed after having designed the boat then made a full scale wooden plug (plugs). We couldn't afford to buy decent kit but as engineering/product design students we could make our own. :) This is GRP work of course.

    The moulds we made (we did two) lasted with care for about 50 builds each, all sadly gone now. I'm talking about the mid seventies-early eighties now. They paddled well.

    Over recent years we had a guy who wanted some frames made for (serious) dog sledding training hacks. Based around cycle components it was a cut it, try it and fit it, cut it and shut it for the first two or three. We then finalised the design and made a series of jigs and fixtures to replicate the best one. Along with a cutting list, spec chart and so on. This was much the same as we did when we entered National Schools Karting Association Championships. We got some great kit and won some gongs.

    The prototypes are frustrating but challenging and relatively fun - the series production can become mindless tedium but that's really where the money and time is made back.

    You will need very good kit and a skilled operator to eliminate (or even lessen) tight radii on big tubes. Compromise has to happen.

  14. It's 17.23 here.......
     
  15. Are you going to do a parallel run, by painting them gold and adding some twinkly lights for the US market? :biggrin:
     
  16. It's a damned fine thought.
     
  17. One more gone to a member of this parish - very many thanks.

    One more available at this time.

    The finished version should be available to see at Prescott hill climb next weekend where we have a trade stand.
     
  18. I'll get the pics up later today.
     
  19. Well that was quick - I've names against all the sets in this batch and the prototype (and 4 down payments). Many thanks for the support and advise this project has attracted.

    I'm not intending to organise another batch straight away but if there is enough interest then I'm up for a discussion.

    Have fun,
     
  20. I have the pics - I'll do it tonight, after 10.
