When you think of a dyno, you think of dyno tuning and ecu flashing. Most people do. But today, we show you other ways we use our dyno to help our customers with their bikes. Today we have a 2008 Suzuki GSXR1000 in. The customer previous got a ecu map from another shop in hopes to fix some of the issues this customer was noticing with their bike. After running the bike on the dyno, we noticed right away that the AFR was waaaay off. Which gives us an idea that the fueling system is acting up. This could be a number of things. Symptoms of a bad fuel pump, clogged fuel tank vent, bad fuel door gasket. There are a ton of reasons that could cause a loss of power and fuel on a gsxr. Once we got the base runs done and we were able to check the fuel pressure on this motorcycle, we determined it was a fuel pump issue. Once we opened everything up for an inspection, the pump looked decent, but inside of the tank did have some corrosion. The vent lines also looked a little rough. To start, we cleaned up the fuel pump which did help a little bit, but we were still having some fueling issues which lead us to replacing the fuel pump all together. Once we got a new fuel pump installed and re-ran the bike on the dyno, the numbers improved right away!! Not only does this bike RUN better, but the overall power gains are massive!
