This throttle linkage caused me some issued the other day, it jumped off and left me with no accelerator, luckily this happened at home and I was able to quickly fix it. I realised in that instant at that really I need to do something better and more robust to stop this from occurring again. The old linkage was a 5mm diameter bit of aluminium bar, so very soft and the end links didn’t fit quite snuggly enough. So I purchased some stainless steel M5 thread bar and some M5 ball joints. I made up this replacement rod with ends.. That is not going to drop off I don’t think.. I hope!
