Nice write up. I have the Idea brand, think it’s a knock off of yours. Mounted it to the tach itself after red line with double sided tape. Was the first mod I did to my 919 given the fact I don’t remember what I ate for breakfast everyday let alone what gear I’m in, I’m happy with it. Been on the bike for 3 years with no issues.
It doesn't actually sense the gear lever changing positions?
Correct. It's using the math between the two sensor outputs. When you pull in the clutch between shifts (or in neutral, or at a complete stop), the readout shows a minus "-" symbol. It's pretty quick to respond when letting the clutch out.
If you shift not pulling in the clutch does it know what gear you are in?
Never tried, but I would imagine it does since it's working off a formula of the engine and drive sprocket rpm. An interesting bit in the instructions says that if it shows a dash symbol while in gear under an acceleration, it could be a sign of the clutch slipping.
All my next mods are going to be quality of life electronics: STS smart brake light, the Trucklite7 headlight, and this gear indicator. I’m constantly reaching for my imaginary “7th gear” on the highway. Down the road, let us know how this install and brand hold up in the long term
