I think you're spot on there... You can get decent results doing it by feel, but at the end of the day why settle for decent results? I've not had mine dynoed properly yet as I've been changing things bit by bit, so I've been happy just to have it running well, but at the end of the day if you're sopending the cash and effert to fit jet kits, exhausts, why stint on the setup?

Having said that, it does probably make sense for the mechanically handy to get as close as they can before going to a dyno operator, since it'll make the job easier and quicker, and therefore cheaper.

Also, i was just thumbing through the Demon tweeks catalogue, and I found they sell a couple of a/f gauges... I know throttlecraszed on SVrider has a setup like that fitted to his bike, but I wondered about building a temporary sniffer that could be stuck in through the end can, wired along to the dash, and used while home jetting...
