Were they genuine Triumph levers?
Some aftermarket levers are known to cause various errors on 800s and Explorers (search this forum) due to being poorly designed and/or machined and therefore not triggering their respective switches correctly.
No, they are not original ones. But at least one other person successfully installed them. They seem to be of decent quality.
However, the construction is pretty simple and I can confirm the clutch level engaging a switch underneath when pressed.
I do not see any other electronics around it which could be affected. Anything, in particular, I should check?
