The ECU is detecting that the TPS has been removed along with the stock carb. To disable the warning light you just need to cut the pink wire with the purple stripe shown below. (I terminated mine with 1/4" quick-connect electrical connectors in case I want to reinstall the stock carb and OI system when I eventually sell the bike.)
I put a 36mm Lectron with 3-2M metering rod on my 2016 Xtrainer a couple of years ago and love it. Works great for the 2,500' to 10,000' elevation ranges we ride here in Idaho.
From the 2017 300RR wiring diagram in the Owner's Manual (2018 should be the same):Deck1 wrote:I thought there would be mention of something on Beta website for TPS removal kit, but no dice.

It's mentioned in this Oil Injection Removal Kit guide on Beta USA's support page, but that guide hasn't been updated to reflect the new speedometer manufacturer Beta switched to starting with 2017 model years. For 2017 and 2018 bikes the pink/purple wire color code is still the same on the Beta wiring harness side, but the speedometer electrical connector and pinout are different than 2015 & 2016 bikes.
