Speedo drive direction with reversed calipers?? 3CL

I've reversed the calipers on my 3CL to behind the Ceriani forks and the speedo drive is now on the left hand side, which seems to cause the cable to spin the wrong way for the 2 ND speedos I have.

Is there a fix for this if I want to keep the calipers rear mounted??

The speedo drive must remain on the right... lots of discussion on caliper reversal.  The search button is your friend.  :D

Red. Umm. because I didn't think and thought I had to...Now I'll have to get Mick to refit the tyre and then I'll probably have to re-shim the calipers...bugger. Or, I could make up an excuse and say it was the amount of beer that I had drunk that night....

sfcpiet. Yeh, I did a quick search this morning and didn't come up with much. Obviousley others think more than I do about whether the wheel needs to turned around.

Thanks

By saying you will have to re-shim, suggests you currently have shims between the forks and callipers. If that's the case then you have some other isuue to deal with too. Why are there shims there in the first place?

I just made up new spacers to centre a front wheel this weekend. Took 3 goes (beerless) before I got it right (I now have .5mm variance between the left and right forks and rotors. That's close enough for me, given that may change when I do the old bouncie bouncie before I tighten up the axle), no shims and callipers are almost centred, bar the .5mm on one side. 

 
Greg,

Once the wheel is centred in the forks, the calipers should not require any shimming.

Do be aware the wheel/spacer assembly is NOT a snug fit in the forks.  The axle is pulled through the RH leg against the speedo drive and tightens up the wheel and LH spacer against the LH leg.  By reversing the fork legs, you need to take into account the space normally left between RH leg and speedo drive.  You need a shim to keep this spacing and to aid assembly, I'd suggest you remove the same amaount as the shim from the LH spacer.  The status quo is then restored.

Simple, innit? :D

In my own defence, it is my first Breganze. I've owned a Zane sine new. I referred to the photos of when I bought the 3cl, and the speedo drive was fitted to the left hand side, but it did not have a speedo or cable fitted. Why, I do not know.

I've always shimmed the calipers on my Guzzi's so that the pistons are as square as I can get them to the disks, and the calipers centred as best as possible over the disks, so just did it with the 3cl for the fun of it.

I am aware that the axle is pulled through and tightened before tightening the axle in the fork, but Piet's comments will have me having a closer look at the spacers.

Once it is all set up again and the axle tightened I'll make sure the forks slide easily before I put the springs back in.

Regards to all

You can leave the speedo drive like that but you need to turn the engine around as well.
As an aside, calipers are fine in front of the fork.

Yeh, well, that  solved another problem for me, cos when the back tyre was fitted up the wrong way on the rim I put the drive sprocket on the left, and now that I have put the motor in backwards, it all seems to fit together fine. (sort of..)
(with a few little mods with oxy/acetlyne).  the problem now is, I have to use aerostart into the exhaust pipes to get it to fire! and it won't run. Well, it did, sort of, but I ran into the workshop wall behind me...

What else do I do but take it to Red to sort out?

Regards
