Hi All.

Can anybody help with these 2 questions please?

1. I've ordered a kph speedo to replace my mph one. The housing on the one I am waiting for is not in that great a condition, so I want to use the inners to replace mine. I have looked around but have been unable to find out how to take them apart. Has anybody done this, or can someone point me in the right direction for instructions, please?

2. I would like to reduce the mileage on the replacement speedo to show the correct mileage for my bike. I know I can use a drill attached to the speedo cable, but I need to forward it on about the equivalent of 80,000 miles:giveup: Is there an easier way to do it? I'm assuming I can't drill it backwards!

Thanks in advance.

This isn't specific to the B1200, but usually an older speedo is sealed. It has a housing and the speedo is put into it and often secured with a few small screws. Then they put on a rubber ring that goes around the face of the speedo, the glass, and then the trim ring. The trim ring extends down to the housing and is then crimped to it around its entire circumfrence. This seals the unit. You can uncrimp it. It's not fun, and you have to be careful not to marr/distort the trim ring.

The unit is put into a cup like housing. This is easy to change as it's usually just a few small bolts. The difficulty of your job will be determined if you need to just change this housing or the trim ring.

In regards to the odometer, you can't spin it backwards to roll off miles/kilometers. If you are changing the trim ring, you can take a look at it when you get the housing apart. Typically you'll need to remove the needle and the face plate to even attempt to get in to it. It's not for clumsy hands, and you'll likely find parts that are peened together making reassembly difficult if undone.

Consider how many miles you are advancing and if it's worth it. If you spin the speedo at 100 mph, you'll still only be putting on 100 miles per hour. For 80,000 miles, that is 800 hours which is about 4.75 weeks if you run the drill the whole time.

In the future, you should include the year of your motorcycle. I had to make the assumption that you have the older style 1200 because you mention using a drill to advance the speedo. The older model has a separate speedo and tachometer. The late model units are electric and, even though they look separate, are a single unit. You can change the trim and housing on these units easily as they are are only held together by screws.

Hi and many thanks for your very detailed reply.

Yes, it is a 1998 Bandit, and the mileage is a little over 7000 miles and the replacement speedo shows 33000 kms. I have not work it out exactly, but off the top of my head I guess I'll have to move it on about 78,000 kms, more or less.

So, bearing in mind what you have said, I think i'll just have to swap the complete units after taking photographs of my speedo in place. It's a shame though

As an aside, I can remember in the mid-seventies that I could use a match to move the individual number wheels, (on a Ford Escort), but things would have changed since then, I guess.

Thanks again.
