I wonder if anyone has run into this before, I recently had my bike tuned on the dyno at a local shop. my question is this, on the graph where it shows your hp and tq the line is not smooth after about 7000 rpm, it looks more like a polygraph machine when you are telling a lie, spikes up and down. is this normal or is something wrong with this dyno,, all the graphs I see here have a smooth line, making them easy to read.
