Not today, but over the last week:

* troubleshoot issue with temp gauge blowing Fuse #1 (many, many thanks to @TheMightyGriffon for his incredible support), including measuring resistance at temp sender (good)
* repaired my 'spare' temp gauge (center wire busted off ring terminal) and put that in place of the shorted temp gauge (fuse blowing problem solved)
* as long as the lower and belly fairings, fairing pads and seat were stripped, installed new light weight battery, pulled cylinder head cover and checked valve lash (all good!)
* changed all fluid and filters
* reinstalled all the various fiberglass bits and seat
* discovered the clutch pack was seized, so busted that loose doing the "5th gear + aggressively rocking" maneuver
* fresh gas + techron
* changed batteries in Fobo TPM thingies and aired up tires

Just waiting for this freaking rain to go away and I'll take her for a rip.

Yesterday, seasonal oil change on the Brick and the Boxer.

I repaired the constant ON the NEUTRAL LIGHT by replacing the PNP transistor BD370. The instrument cluster had to be dismantled to access the circuit board. I desoldered the OEM transistor, cleaned the three mounting points, and soldered the new one in place. Before reassembling the entire front end, I plugged in the instrument cluster for a successful test. The neutral light is on when in neutral. When I shifted it into first gear, the neutral light went out, and the same happened with the other gears. When the neutral light stays on, regardless of which gear is engaged, it is a serious safety issue. In any gear, the bike can start without pulling in the clutch. Sure, you can use the gear indicator, but mistakes can happen. If this happens to your K you'll have to dig deep to locate dead stock. When you solder, keep your iron no higher than 600 degrees f to reduced overheating the new transistor. Use a magnifying glass. (K75s 87 Original Owner)

Good information to share, thanks.
Did you use a BD370 transistor or a suitable substitute?

You are welcome. I used a new deadstock PNP transistor BD370.


NOTE:
It's a known issue and its independent of the Transmission Switch (Gearbox Position Switch) indicating current gear positions. It's important not to get confused. The switch and any associated problems employs different troubleshooting methods. In my case the gear indicator showed each gear correctly which told me the transmission switch is functioning. The neutral light just would not go out no matter which gear selected. Replacing the transistor fixed that. While in the instrument cluster check for loose components. I found one weak solder joint so I fixed that.

I rode home my second brick! Chilly two hour ride from outside of Colorado Springs back home to Denver.

I’ve had a 95 K75RT since 2014. Fairings came off in like 2017.

As of today, I also own a 95 K1100LT which I rode home for less than $1k.

I need to stop buying and start selling vehicles.🙃

Got in some Pirelli Angel GTs for my K1100LT. I’m not stoked about the idea of changing them but excited to get the new wheels on new tires. Ride On came in, too.
