How I load a Honda Dax on a trailer

The trailer is a simple model suited to load motorbikes. When I needed to transport a Honda Dax a problem an inherent problem of this type of cheap trailer showed up. The wheel diameter of a Dax is a lot smaller than that of a motorbike. When the wheel is driven up to the end of the sledge into the stop, the steering is over the edge of the trailer. When you fasten straps and belts over the steering fork and connect them to the edge of the trailer bottom, then the dax is pulled out of the sledge stop.

So I needed a way to fix the straps on the steering head lead them to the sledge stop and lead them back to the fixing points at the edge of the trailer. This way the connection from the steering head is pulled forward to the sledge stop and this force keeps the wheel inside the sledge stop.

I am using straps without ratchets:

For each side there are 2 hooks, the shortest one has a ratchet. For the motorbike you need 4 sets of 2 hooks.

SimpleStraps

The 1st image shows the connection if 1 set of 2 hooks on the left front side of the bike. The shortest one is connected closest to the bike, the long one will go through the ratchet and you can sit on the Honda Dax to pull its shocks down and simultaneously tighten the strap.

DirectionsFront

The hook of the longest strap is fixed to the connection furthest from the sledge at the edge of the trailer. The strap is led to the sledge stop, twisted 360° around it and then led over the steering fork down to the the ratchet. The strap is led through the ratchet. The other hook is connected to the fixation point closest to the sledge. Pull the strap lightly, to keep it from falling over.. You need to do the other side now.

Repair Breva rear footrest

One of the rear footrests did not collapse any longer when I bought the machine. After cleaning the mufflers I decided it was time to fix this. After dismantling I found that the ball and spring mechanism was rusty. A thorough cleaning and reassembling fixed the problem. Now the footrest clips in and out without any problems.

Removing and cleaning the REAR footrest

  1. With a plier remove the blocking ring (2) from the notch bolt (1) and put it aside.
  2. While holding your hand under and around the footrest to hold any pieces from falling on the ground, remove the notch bolt.
  3. Carefully slide the footrest (14) out of the bike frame, keep the fixing plates (9) together, because the spring (12) might push the little ball (13) out and you don’t want this to disappear on the floor.
  4. I have cleaned the rusty ball and spring with a little WD-40 spray. The footrest was cleaned with aluminium cleaner.

Reassembly

  1. Put the spring in the footrest
  2. Place the ball on top of the spring and push it so that it sits in the footrest.
  3. Now slide on of the fixing plates over the ball, try to keep the ball in the hole of the footrest. The 2 fixing plates are symmetrical and can be on either side of the footrest. The fixing plates have one rounded corner, this matches the rounded corner of the holder on the bike frame and not the rounded corner of the footrest.
  4. Place the other fixing plate on the other side of the footrest.
  5. Keep the notch bolt ready.
  6. Slide everything in the holder, while keeping the ball and spring inside the footrest.
  7. Insert the notch bolt from the top (on the picture of the rear holder it is on the top right hand side) and slide it downwards(on the picture to the bottom left side), through the fixing plate and footrest until it comes out at the lower side.
  8. Keep the bolt in place with one hand and test the footrest a few times if it clicks in the up and down position easily.
  9. Put the retaining ring back over the bolt.

Dismantle, clean and mount a Lafranconi muffler

To thoroughly clean and polish the Lafranconi mufflers on my Breva 750ie, it is best to dismantle them. In this article I wrote down how to dismount and mount the muffler on the left side.

Tools needed

  • Hex key to remove heat shield
  • Socket wrench to remove muffler support near foot peg
  • Wrench with box-ring to loosen exhaust clamp

Muffler parts

Parts list was found on the Stein-Dinse spare part online shop

Breva750_left_muffler_partlist

  • 4. Exhaust clamp
  • 10. Muffler
  • 14. Muffler holder Left side (connected behind rear foot peg)
  • 19. nut (3 nuts in total, 2 to hold muffler, 1 to connect behind rear foot peg)
  • 26. heat shield
  • 27. hex socket screw M6 10 (M6 = Metric 6)
  • 28. washer 6,4X13x1,5
  • What is not in this picture: between the shield and the muffler I found 3 larger washers stuck to the muffler with exhaust paste.

Walkthrough

  1. Remove the heat shield, by unscrewing the 3 hex socket nuts
  2. Loosen the 2 nuts on the muffle holder, this is only to make it easer to unscrew them after the muffler has been removed completely.

  3. Loosen the exhaust clamp so that it slides over the exhaust side, away from the muffler.Jan 039
  4. Loosen and unscrew bolt from the hex socket nut behind the foot peg.Jan 040
  5. The parts after removal and before cleaning.
    Jan 041
  6. New holes had been drilled in the muffler holder. Since it was a 2nd hand motorbike, I have no idea if this was done by the previous owner.
    Jan 042
  7. The bits and pieces after cleaning. The muffler and muffler holder are cleaned with cotton cloth and chrome polish. I rinsed the rusty bolts with WD-40.
    Jan 043
  8. After mounting the muffler without tightening the screws, make sure that the exhaust clamp nut is not too horizontally tightened otherwise the end of the nut will prevent the side stand from moving in. Below picture was taken with the camera in horizontal position. The nut head on the left must be higher than the tip.
