Hi I have a 2001 Gsxr 1000 drag bike that I am currently bringing out of retirement after sitting for 10 years… new clutch springs, valve seals, valve springs, fuel pump, sent out injectors to be cleaned professionally through Schnitz Racing. And it’s currently on a stock 12v startup. All cylinders are getting fuel as well as great compression. (Recently shimmed the valves to spec) however my #4 cylinder is misfiring. At an idle I’ll pull the plug for the ignition coil out and it makes no difference. Can anyone help point me in the right direction I’m currently hitting my head against the wall stumped, Thank you!
