I swapped the oils in my fxsti for syn 3. once i turned the bike on i got an oil light. it has the right amount of oil. the oil light is on at idle and goes off at rev, changed oil sensor promblem is still there
Like some said above....
IS the IDLE set UP where it belongs?????
Slow idle WILL show the same problem,,, TC motors need 950/1050 rpm at a minimum! for the idle.
IF it didn't do it with the Mineral oil, Just when you changed out to the Syn3.... I would NOT use syn3(.)
MOST of the responsive Members here would Suggest almost any other oil before SYN3. (.) I'd rather see you go back to the regular HD oil (much better) BUT the light should NOT come on just with the different oil at idle.
The pressure at idle tells me that it may be the oil pump BUT testing IS needed.. Pressure gauge at idle cold and idle warm ?
what is your basic pressure
Fast idle at 2000 rpm ? cold 40 and warmed 30/35 ? If basic pressure not there You Do have a problem.
IF really low shut it off and do what is necessary.. Like Smitty says.
questions you need to answer for us: How many miles on the bike?
any Modifications now or before the oil drop off pressure..
I for one would suggest the "KIT" IF the oil pump is gone... The stock oil pumps NEEDED to be better than HD put in the earlier TC motors... Maybe NOW is a good time to UP-grade your engine..
Lucky you if only the oil pump (mis-aligned possible) and not the engine bearings worn out.
The conversion KIT does the change over of a Lot of Needed up-graded parts for your bike at a VERY Low cost... KIT #25284-08 Parts 429.95$ gets you converted to the Hydraulic tensioners with new cam plate, chain gears, chain,New style oil pump with more volume..... separate pricing would Shock you!
Let us know where you go with this and more help here IF you answer the basic questions about your bike and pressure check.
