Need to know the fuel specs and the injection specs for this bike
The bike had been sitting up for awhile and would not start. Drain the fuel system and injectors. Bike is now firing but I need to know the correct fuel and injector specs.

Yes I to have washed a bike to death.You will need to dry the air filter .Is you bike fuel injected?If so take a hair dryer and warm all the connections concearning spark and fuel injection .You should then put dielecric grease on all your connectors.If you bike is carb model then just drain the float bowl.
The fuel in the tank may have crystallised and clogged either the needle valves if carb( which will force fuel out through the overflows if you change the fuel. If injection it may find its way through, with new fuel but get some injection cleaner as a tank additive. Job 1 drain out tank, shake some new fuel around to wash it out job 2 remove fuel tap check for a build up of gung and crystallised fuel job 3 new fuel up. all the best [email protected]
Just a thought as you asked...sounds like a poor throttle position potentiometer ... throttle cabled to butterfly most likely and if ECU dosen't know throttle plate moved you will see this symptom . If electric throttle , can you see(hear) plate moving whilst twisting , if so measure resistance/voltage on pot. . I do not know if resistance of position sensor can be measured while twisting throttle or pushing plate (bike off , battery disconnected or ignition off)

These have a central port injection system. The central port injection is very finicky on fuel pressure.
Spec off the top of my head is 58-60 psi. As little as 1 psi under minimum spec is enough for the vehicle not to start.
You first step is to accurately measure fuel pressure with a good fuel pressure gauge.
I'll see if I can't round up the actual spec for you in the mean time.
Let me know if you have any questions and I'll do my best to answer them. Thank you for using FixYa.com!
I need more information in order to make an educated evaluation of your problem. What does the bike do, engine turns over but just won't fire or what? Has the bike been sitting for an extended period of time? Security system? Fuel injected or carb equipped?
The oil is drained through a tube that runs down behind the transmission all the way down to the lowest point on the frame beneath the transmission. I don't know what year they changed the location but some models have a plug in the end of the hose on the frame tube. Later years, the hose goes on down and connects to a nipple on a crossover bar. There is a plug underneath the crossover bar that screw up into the crossover bar. Take the plug out to drain the oil.
To drain the transmission, look at the chrome clutch release mechanism on the right side of the bike, Just below the bottom edge of that, you'll find a pipe plug, remove the pipe plug to drain the tranny.
The drain for the primary is on the very bottom of the case at the back directly beneath the derby cover.
If your bike has been sitting for a year, you're probably going to have problems with the fuel system as well. You may have to take the carb off, disassemble it and clean the jets out.
I have no idea how to service a fuel injection system.
If the bike hasn't been started in that long, you may want to talk to the dealer first about the fuel injection system. Since I don't work on fuel injected engines, if I got a bike in that had been sitting for that long I'd have two concerns, the condition of the fuel delivery mechanism (carburetor in my case) and the fuel tank and fuel pump. Injected engines have a fuel pump as well.
In conjunction with all the other stuff you're talking about having done, this is going to cost a wad of money. I'm guessing a $1000 for the tires and the final drive belt in this area. If you have to start replacing throttle bodies, that could get expensive. Unless you're getting a steal on the bike, you go upside down in this deal. Talk to the Harley dealer first.
You didn't say whether the bike was carburated or fuel injected but I would assume it is fuel injected. You'll have to take it to a dealer unless the computer has been changed. They can scan for codes and reset the idle speed.
Check to see if you have spark. You'll need an inline spark tester that goes between the spark plug and the wire. You can't have the spark plug loose or the Ion sense will not allow the ignition system to spark. Is it carb or fuel injection. If it's fuel injection make sure the fuel pump is kicking on. You'll hear it when you turn the key on. It will cycle then shut off, it builds up pressure in the lines to accommodate the injection. If it's carb make sure you've got gas at the float bowl. loosen the small drain screw on the bottom of the car. Fuel should run out. If there is fuel in the float then I would go for flushing the gas tank to remove any old fuel in the tank. If the tank wqas stored with some fuel init, it could have alot of water in it due to sitting for so long. If the gas smells nasty, flush the tank and pull the plugs, I'd replace them or clean them with a spark plug cleaner ( Sand Blasting ). Remember, gas that works in a car doesn't mean it will work in a bike, quad scooter etc. Motorcycle are picky when it come to there gas, and you can get all sorts of symtoms from having bad gas. Gas only has a shelf life of approx. 30 days before it starts going bad. Also, try using mid grade or lower fuel too. Since gas prices went up, the premium gas is sitting in the tanks longer causing them to not work as well as it used to for bikes. If you have a carb make sure that you are getting gas flow. The diaphragm on the petcock needs between 2-5 p.s.i. to activate this.
Why do you think the valves need adjusted if only 500 miles on the engine? Your bike is fuel injected. Chances are 99.5% that any problems with how the motor starts and runs is the fuel injection system. If the bike was new in 2000, then it has been sitting a Very, Very long time. Gas in the tank evaporates and gums things up. Get the fuel injection system thoroughly cleaned and the problems will probably disappear.
