And a Happy New Year to you too, John.
Your photo can’t be found by me – I wonder if others are unable to see it too. As you have a T150 Special, I wonder where your tacho cable is actually routed. I can only comment therefore on my own machine, a T160.
The T160 has the tacho cable entering by the primary drive. If I have any hot exhaust downpipe contact issues, it’s with the left hand cylinder header pipe. That is avoided by a stiff wire bracket that is mounted via the exhaust box cover bolt which, I believe to be a standard fitting.
Just a thought – you’ve posted this enquiry via the “Events & Ride Outs” section. If you copy your text and post again under the “Technical” section, you’ll likely receive more replies of a greater width of experience than me…!
