To make a long story short. My Bike ran good all last year until I began riding this season, long about April. Started to run erratic so I changed the fuel filter which was original ( the bike has 9600 miles), to no avail. Sputtering and smoking black. Checked fuel pressure 36psi. Replaced fuel with fresh still no luck! Read this forum for hints and found Bert's stuff. Checked and replaced hall sensors...stil no good checked and replaced water temp sensor... NOT! Checked all connections,grounds and hots replaced battery and had alt checked still ran bad and sometimes not at all. Checked ignition switch tested spark plug leads which showed infinite resistance but had good spark thru them. Replaced plugs and repaired a bad vacuum leak at the throttle body. Ran with the tps unplugged and still this thing is not running I am to the point where it started and shut off as if the ignition switch was turned off. Floods the engine terribly. I unhooked the return line to the tank and did manage to get it to run a while longer but plugs are fouled now. I was thinking fuel pressure but it checked ok. Checked resistance values as described in Bert's pub for the MAF which is as follows pins 7-5=108, 7-8=361, 8-5=363, 8-9=189@ 85deg F
I am extremely frustrated and do not want take to dealer! They seem to know less than you anyone or do not want to share info!
I seem to be overlooking something but cannot put my finger on it. It ran fine last season WTF HELP!!
