When I start my bike it has no f1 light or fi light (who cares which one). I take off and can go through every gear with no light until I let the RPMs drop while in gear or engine breaking. When at a low RPM the light comes on and simultaneously the engine seems to break harder and it sort of boggs down. Also, when I'm riding and I pull the clutch in and I try to rev match the RPM drops so fast that the throttle almost wont work to bring up the RPMs! At times this will make the bike die if the RPMS drop all of the way. As soon as I shut the bike off and start it back, the light is gone until I do as explained above. PLEASE HELP!?
