Speedo Healer V4

[Pickaxe]

It's the first bike I've felt the need to correct the speedo error, but, having calculated the error at somewhere between 9 and 10% and with the large digital display in my face, I decided to part with my £84. The market leader seemed to be the Speedo Healer Mk4 from Healtech and I purchased the unit itself and the specified wiring harness from BDS Racing. The items arrived by 1st class post the following day so the service was good.

The kit comes with all the required terminals and connectors and requires no soldering. Preparation involves removing the side panels and lifting the tank. Strictly speaking you could just remove the left side panels, but I removed both and raised the tank for greater access when feeding the cable through to the under seat compartment.

Unfortunately, with the VFR, you are required to cut the speedo signal wire at the large connector block, however, this doesn't present a problem and there's plenty of wire to play with. I deviated slightly from the instructions here, as on my 2018 model, there was more wire length to play with on the other side of the connector block. You have to splice two further loom wires and after securing the actual unit on top of the fuse box lid, job was done. If you take your time, it's not a difficult job.

You can program whatever correction figure you want into the device via  the two selection buttons and I decided to go with - 9.1% as calculated by the Speedo Healer phone app. A test ride confirmed the unit worked faultlessly and delivers exactly what the advertisement blurb states. Recommended if those large optimistic numbers on the dash annoy you.

Glad you found a successful fix.  On my 2017, the speedo and the GPS are either matching or showing 1 mph difference up to around mid-80s.  Not sure about the error above that, as I tend to be focused away from the GPS on those occasions.

Come to think of it, my speedo also matched a deputy's radar (74 mph) when he pulled me over last week.

I've thought about doing this myself, not done it yet as I nearly always have the SATNAV which I use for more accuracy.
I find the incorrect speed, as you said 'in your face' a distraction.

A question you could maybe now answer, does the healer have any effect on the odeometer or fuel values?

Because mine is exactly 10% out it doesn't bother me - you "work out" your true speed (with regards to speed limits) without any actual effort. Would be better if it was accurate but, failing that, being 10% off is handier than being 4 or 7 (etc) percent off.

I'll get back to you on that one. According to Healtech, yes it does effect the odometer and mine was originally reading 2% over.

That's strange as the speedo and odo have different readings.

Again this is described as the norm by Healtech. Speedo up to 10% high and odometer slightly over is what most manufacturers program in.

I wonder if it's a regional thing? Ultimately, apart from one or two slight variables like tyre size, the accuracy is down to the manufacturers programming of the ECU. In the UK, the law has always stated, Speedo accuracy must be within 10% but should never read under the actual speed.
