Gearing

[The Stranger:Me]

I notice a lot ot talk about adjusting gearing.
I did on the Yamaha and it certainly helped that bike as the power band was quite high in the rev range.

On the Yamaha the speedo is driven from the front wheel, so remains accurate.

When I got the K3 from LooseBruce the speedo was reading about 35km faster than actual. i.e. at 100kph the speedo was reading about 135.

I have gone back to a 17 front but the rear is still at 47. it is now about 10% out i.e. at 50 it reads 55, at 60 it reads 66, at 100 it reads 110.

It is not only the speedo which is out, but the odometer. LB's GSXR reads 35,000km on the speedo, but has possibly only travelled 25,000. This has a direct impact on resale value.

So how do you adjust your speedo for a gearing change on a modern sport bike?

You can buy a little gizmo called a Speedo healer....not sure where from, seen it on the web.

or you can take a vivid and mark the correct speeds on the dail, and when it comes to resale grab out the power drill and the odo and run it backwards a few thousands of k's....

What are you going to do with the drill?
They are electronic, not mechanical.

that serves you right for getting a flash bike!

speedohealer does not change the odometer, it changes the speedo speed showning,

Way i have read things. said changing your gearing does not effect odometer over all that much. yes it does a touch but very

[SimJen]

Don't know what you mean it won't change the odometer? on an electronic speedo, the pulses from the speedo sensor (off the front sprocket) tell it how fast and how far it has gone.
Speedo healer will make the speedo read correctly, consequently the odo will remain accurate!

[Cajun]

yes it does effect it but when iw as doing some reading said over all wasn't to much, but that might be to when people do mild gearing changes, not aggressive changes like bruce

saying that i have ordered a speedohealer for when my sprockets arrive changes come

Hey this SpeedoHealer sounds like a worthy investment for anyone who wants an accurate speedo, might just get one meself.

There is one sensor, on the front sprocket, it picks up the number of revolutions of the front sprocket, that is it. From this it calculates the speed and distance. I can see no other way the odometer can be calibrated. It must be out by the same percentage as the speedo.
