Guzzisti (2/5)



  1. The one one my 2005 Coppa Italia seems to be made of aluminium. Use a 6-corners pipe of 20mm (not a 12 corners pipe). Then you could clean it from the inside. I think pressurized air would do the job. (Not acetone - since that would destroy the window of plastic) The part number should be 01205730 according to my book. Rolf
  2. Send me a mail (rolf.halvorsen@mail.com) and I will send the picture to you. Then you can do this for me. (Thats why we have friends.)
  3. Please help me. I am too old to know how to increase the picture.
  4. For the 6-speed gearboxes it has a similar locking mechanism. So you can just leave it - it will make no problem for you.
  5. The special wascher are hardened steel waschers of 1,0mm thickness. (You can get them with a magnet) 1,0 + 1,0 = 2,0 (I have bought about 100 of these - so contact me if you need some). Since the inner and outher diameter are close to identical with a standard 6mm washer - DO NEVER USE ONE OF THEM! The standard wascher are 1,2mm thick. 1,2 + 1,2 = 2,4 THIS WILL SQUEESE THE AXLE SO THAT IT CANNOT ROTATE! 5- and 6-speed gearboxes uses the same technic, but the axle has different number of tooths.
  6. This is a complete kit! A new cable and special adapter is included! This will completely replace the always breaking angel drive!
  7. Article No: 04768300 is the replacement speedo cable. tlm.nl Rolf
  8. Do NOT remove the part on the gearbox. Remove the thread part on the wrecked angel drive - and put a rubber disc (which you can make yourself) onto the male part on the gearbox - and screw on the female part. Thereby you seal from water to enter the gearbox. I hope you understand what I mean. Teo Lamers (Holland) has a replacement wire that works without the angel drive. I do not have the article number at hand. Maybe tomorrow.
  9. These arm to the engine case will help stabilize the engine from rotating - and thereby reducing the load on the top gearbox fixing point (where the cracking problem has been).
  10. What is the different between my theory about the casting prosess that may have been changed - and what you wrote?
  11. My 2005 Coppa Italia has no extra gearbox support. The pictures from Tom shown the right side of the gearbox house. I have rebuilt 5 such gearboxes - and all had leakage on the left side.
  12. Did you leave your bed with the wrong foot first today? Since I have some knowledge about casting in aluminium - I thought that my teory could explain why the later boxes seems not to crack so often as the earlier types. Smile to the world - and the world will smile back.
  13. If the producer has changed some parametres of the casting process - or increased some radiuses in that dangerous area, we will never be informed.
