    Hi all. Has anyone been pestered by an intermittent non-starter scenario due the clutch lever switch being ever so slightly loose. It works with a small wiggle back towards the lever. Did you find a work around? Replacing the switch and loom is a pain, in the words of the chaps at my local dealership.

    Is there a screw that holds the switch in place that might be loose?

    My brake switch is part of the harness also and it's been acting up. I found that a Japanese bike switch fits perfectly but the wires need to be clipped and female spade connectors added. Once that's done, it'll be easier to replace in the future. Maybe the clutch switch can a be upgraded the same way.

    Hi, Tom, thanks for the reply.
    No mate, the switch has two lugs that sit in slots cast into the lever block. Thinking about it again, I could try some small shims which should hold it tighter.

    Unfortunately it is a common problem with street triples, out of the street triples I have owned, 3 of those had the fault, as did a Sprint 955i RS that I bought new, that failed whilst under warranty twice, and a third time out of warranty. I recall posting a thread on this very subject some time ago. What I did to solve the issue was replace the switch with an identical unit from a Japanese model, I cut the wiring from switch and loom soldering the wires together, then heat shrink over to protect the joint from water ingress. The main issue I found was water ingress combined with tight wiring routing causing internal fraying, jiggling the wires about sometimes works in getting a machine started, however the only remedy is replace the unit, the Street Triple 765rs range suffers from "joystick" failure, many people have had this issue. I have no knowledge of who Triumph use as their supplier of switchgear, although it is most likely Chinese, the fittings are not JIS so I very much doubt they are of Japanese manufacture. I do know who manufacture some of Triumphs accessories, and these are usually high quality British manufactured.
