last ditch effort
Posted: Mon Feb 08, 2016 3:33 pm
Still no luck in getting my POS running.
Symptoms....Starts ok runs until it starts to warm up then stalls, was doing this when hot now when it reaches only about 120Deg F, will start again straight away then stop after aprox 1-2 seconds, will keep doing this until battery exhausted, allow to cool and it repeats as above.
What I have tried to date
Fuel.... checked lines ok, checked pumps ok, pressure 45psi placed inline gauge pressure does not fluctuate, checked flow rates ok more than enough flow at max usage, tank breather ok, replaced malpassi regs with new 1:1 sards, checked flow under gravity from fuel tank and graphed ok, checked methanol aprox 2% higher specific gravity than pure so it has maybe a little water in it but not enough to cause problems ??, had fuel injectors flow tested and cleaned ok, noid light shows they are firing when cranking at least, maps same as when running ok no change.
Spark.... new plugs, new leads, coils ok, cables and connectors ok, removed all plugs and grounded all fire when cranking, noid light shows coils receiving signal when cranking, will start and run briefly on cylinder 1 and 4 disconnected same when 2and 3 disconnected.
compression... cylinders 1 thru 4 static psi in all greater than 170, valve lash checked within tollerences, sticking valve /s ???
timing..... cam position checked atdc ok cam chain ok, sprockets ok, tensioner ok, removed hall sensors and magnets out board of engine, new cam and crank hall sensors, new high temp and strength magnets, crank and home signals being received constantly no missing signals, fixed timing to 10 deg btdc and checked with timing light ok at least when cranking.
Electricial wiring and halteck ....cam sensor new and ok, crank sensor new ok, checked MAP with vacuum and pressure is reading both ways, water temp ( really oil temp ) working, air temp reading ok, TPS reading 0 to 100 % ok, double checked fuel maps and ignition maps ok, correction maps same as before when it was running, checked intake rubbers for air leaks ok, has battry tested ok but got a new one anyway, all earths ok less than 0.01 ohm difference anywhere on bike, checked all connectors seen tight and secure.
I have reached my limit of things to check any thing I missed ??? ok engine guru's what else to look for?
cheers Gary
