I recently had an FI light issue (came on out of the blue, steady). I shut off the bike immediately. When I tried to restart the battery was dead - no surprise because I could feel it slowing down over a period of a couple of weeks when cranking. I assumed that the FI light was related to the dying battery.
I gets me a new battery from the dealership and pop it in (after trickle charging it to full capacity). However, the dealer was out of the stock Yuasa CBR battery but sold me one that he said would work and was "almost as good". Bike starts up fine but what''s this? The FI light still comes on, blinking twice; but bike is running fine so I ride. However, after riding for about 15 minutes, I shut off the bike and immediately restart it...and no FI light at all. Bike runs perfectly.
However, if the bike sits for a day or 2, the bike will barely idle at startup and the FI light comes blinking twice on which causes the idle to jump to a steady 2,000 rpm. Once again, after riding for about 10-15 minutes, I shut off and immediately restart the bike...no FI light and bike runs perfectly.
BTW, I''m running PCIII, K & N filter and 2 Bros. slipon. I''ve disconnected the PCIII but no change in bike''s behavior so I don''t think that is the problem. I''ve disconnected the MAP sensor & cleaned connections. No change.
I can''t believe the MAP sensor "warms up" causing it run fine after a brief period.
Did I get sold a crappy battery that only operates the bike properly after running at high RPM for a while, thus building up a bit of a charge?
Anyone? Anything?
Thanks in advance!
