How to check alternator output
with engine running you should be able to check alternator output on the battery. put your leads on the positive and negative post and see if it reads more then 12 volts DC. usually charges at 13-13.5 volts
F1 on dash
If you are referring to the red FI light, it is your "check Engine light" and should go off quickly... if it doesn't then you have a "Trouble code" stored in the computer memory and need to have it hooked to a Diagnostic code reader to determine your problem
Why are there no back brakes and no pressure on the pedal?
Check your rear brake master. Is there fluid in the reservoir? Have you tried bleeding the system? Does the operation of the pedal actually make everything operate as it should....is it all connected as it should be? Might require a strip down to replace seals etc. Sorry if none of this helps.
What type of spark plug
I use NGK iridium plugs. The bike runs very smooth at a low idle and the throttle response is spot on. DPR7EIX-9 is the plug number. Remember to take off the spark plug caps before installing as the wires only connect to uncapped plugs. Good luck!
Where is the coolant resevoir located
A C90 is not a water cooled engine. It is a design that uses air and oil to cool the engine. There is no conventional radiator or coolant on this model. The finned cooler you see on the front of the bike is an oil cooler.
