A youtuber I've messaged previously agreed to have a look. He has a car dyno but had already made a bracket for the front wheel which he clamped to one ramp. It worked a treat and after 3-4 hours of tuning it went from "can spin the rollers" to " damn fine". Actual power figures were inflated due to only spinning the front roller. Without the rear roller inertia the dyno thought the vehicle was doing better than it actually was. Either way I'm very happy with the result, 43.4kw indicated. I might be able to get a dyno run in on a known bike dyno to measure what the actual power is later this week or early next. YT channel here -
