Its surgeing and backfireing badly then it will break thru for a second and start surgeing again?
Hi, there is no petcock on a fuel injection Harley. There is a fuel filter inside the fuel tank which will prevent debris getting to injectors so there should be no need to clean injectors. Never had to do it myself in all my years. What you may have is a fuel leak inside the tank on the high pressure side. Have you checked for and engine code (DTC's). If so, post them as they may lead to the problem. If you have access to a fuel pressure gauge, fuel pressure should be around 60 PSI. Anything lower than 45 ish PSI you have a fuel pressure problem for sure.
Hello Samantha! Q:Have you paid any attention to your PETCOCK lately? IT is controlled by INTAKE VACUUM [suction!] You need to drain the old fuel completely,& LOOK right there under the tank are vacuum lines 1/4''? to the PETCOCK. Renew 'em tulsmuc
