Taking apart rvf speedo

[Drunkn Munky]

Dont think i'll be doing the drill method, i know its only a 18v but even if the dremel spins at twice the speed its going to take forever.

The clocks were free so i dont mind having a play with them, there not the same as the NC30 though, the 35 speedo, tacho and temp gauge are all in one unit unlike the the better idea on the 30 where they are all separate dials

You need to see if you can find some sort of gearbox to step up the output of the drill...

Now that does sound complicated, do you think somehow attaching it directly to the cable rather than through the pickup would work faster? I still think id need to get it upto around 1000mph to make it worth while.

I suppose it depends on whether or not the gearbox on the sprocket end of the cable steps up the speed or down. From what I recall with my TZR which has a mechnical rev counter drive, it turned very slowly. Or course, this probably has no bearing on how fast the speedo drive will turn, but I would have thought slower would be better. Less wear, less chance of it blowing to bits if there's an issue, etc. Fairly easy to work out. Rotate the gearbox end and see how many times the speedo end turns, or vice versa. You've obviously got three possible outcomes. If it does slow it down, you're on to a winner. Getting the screw out of the speedo drive to release the cable is a total pain mind you...

Oh, and would it damage the speedo if you find the drill can then get you to silly mph? Will something get mashed inside it if the speed keeps increasing if the needle has found the wrong side of the 0mph stop?

Assuming you can spin the speedo system fast enough to get the result you want, might not the high speed rotation damage something. The speedo system was not designed to be run at 1000s of rpm let alone 10s of 1000s.

Hey Mr T, try this guide out; it's basic but should help you with the disassembling.

Thanks johnnie5, these really are a piss of cake to reset. Sat down with them this morning and it took me the best part of 45 mins, Stripping the clocks and removing the speedo is pretty self explanatory then all you do is insert a small flatblade screwdriver between the numbers and twist in the direction you want the cog to go, thats it. Inbetween the cogs is a piece of plastic just make sure the screwdriver goes the side of the cog you want to move.

I've done my no problem , I had to change my clocks cos they were damaged and all I done was roll back each dial

[Neosophist]

Guess it wasn't NC30 clocks I reset then, memory must be going suck

Perhaps I was thinking of ZXR clocks then, has anybody reset them?

Anyhow, the ones I was thinking off you couldnt do the old type of move the wheels and turn them back, you had to get the metal rod out that holds the numbers and zero them all, then line up all the cogs properly otherwise it didnt line up after a few kms.

glad you could do your bike no problems.
