Question about 2002 Harley Davidson FLSTF - FLSTFI Fat Boy
Hi Vmr2254, remove seat and directly behind the battery is a black plastic box. The cover slides up and off revealing the starter relay and the system/fuel pump relay for you injected folks and the various assorted circuit fuses and I'm sorry you can't find the very first and best tool you ever bought for your Harley Davidson. Despair not, for a mere $6.50 you may be able to download another one from the website below and good luck.

Visit your local Harley dealership and sweet talk someone in the service department to photocopy the required wiring diagram.
Bring a six pack for his trouble.

Replace the petcock. The rubber diaphragm is ruptured. I'd also bet your fuel mileage dropped cause the ruptured diaphragm is allowing raw fuel to be sucked into the intake manifold.

I can't solve this(there are litaraly hundreds of things it could be) BUT I can give you a way to narrow it down a bit.
I'm thinking it may not be running on all cylinders and an easy way to check is to start the bike from cold(do this test in the first few seconds after starting from cold DONT BURN YOURELF),put a bit of spit on your fingers and quickly touch each exhaust header in turn, to see that they are all warming up equally together.This will narrow down if your problem is related to one or more cylinders.
If one or more of the pipes is cold/er than the others then you know which cylinders are causing the problem.
If you find that this is the case- one or more of the headers are cold then.
Remove the spark plugs-Keep in order.Examine the plugs-used plugs tell a story.How do they look?clean?black & sooty?Are they all the same colour?
Re-fit plugs to caps,sit plugs on metal of rocker cover,press starter - cheack for spark on all plugs.DO NOT HOLD OR TOUCH PLUG/CAPS WHILST CRANKING-WARNING - HIGH VOLTAGE- CAN KILL.
I can also suggest a few common problems that bothered the v-stars/viragos.
They were notorious for open circuiting their spark plug caps on either cylinder.Having the coils tested will confirm this. If you have a multi meter let me know & i'll guide you through testing them.
Air leaking at the inlet manifolds-where they bolt to the cylinder-test this by spraying with wd type spray with engine running-if engine revs change-has air leaks(sucking in wd & affecting mixture.)
They even pop the carbies out at the front some times & **** air there.
The inlet manifolds also have hoses & plugs on them(for checking the carbie balance/vacume fuel tap)Check all these for splits & tears-common depending on the condition of the bike/milage/fuel used.
This will not solve your problem but may help you to isolate where your issue lies.
I hope this is somewhat helpful & I'm happy to help if you need after following these suggestions
Kind regards Andrew Porrelli
I hope that this is in some way helpfull.
