Running rich!

[Andypandy66]

Hi all,
Not long got a K4 1000, bought it cheap as a run around, it didn’t run well and I thought it was just stale fuel, anyway I replaced the fuel pump and it now has 3 bar, cleaned the injectors. It now runs but very rich! I’m new to engine management systems (all my other bikes are old skool) so can anyone point me in the right direction for what I should be checking

Suzuki's run rich by default, it's for thermal management, it keeps combustion temps down , but if its throwing raw fuel out the pipe you should check If your air filter is clean and no vacuum leaks,fresh spark plugs, check every tube and anything going into airbox, check exhaust is tight then just ride it, other wise you need to get a wideband o2 sensor on it and log some data, my K9 runs very rich from stock,,
