Hey There,

I bought a used Sportster 1200C almost 2 months ago. It was working fine until today. I went to do some shopping then i passed by the our HD dealer store. Usually, when a bike parks there, they wash it for free. I went to the store, checked some accessories and came back to my bike, found it clean. I started it, it was working well until i stopped the bike for a moment to buy something. Then, igniting it again, my RPM gauge is showing me the ampere on 3000 and the bike's sound is too loud as if am over pushing on the 1st gear. I stayed for a minute but the RPM doesn't want to get lower and the sound is still the same. I decided to stop and start again. But nothing happened it stayed the same. Then i said i'll go back to the dealer around the block. Faced some trouble getting the 1st gear from neutral, and when i succeeded, the moment i removed my hand from the clutch, the bike started moving so fast and the RPM went down to 1500. The moment i use the clutch again, the bike goes straight up to 3000RPM and a huge sound.

I need to know what went wrong with it. Even at the dealer shop they kept saying different problems like air gates, or the sensors, maybe a throttle oil is needed, some other guys said it's the clutch plates.

Can anyone help me please?

Sounds like they got your fuse box wet and something is shorting out. Take it home and remove battery side cover, then use a leaf blower to dry it out. If this doesn't work check for blown fuses.

Pull left side cover.

Pull and clean starter relay.

KNown to get funky when wet.

Use dielectric grease on reinstall.

I called the dealer's store today asking about the bike,

They said the ran a check and the couldn't find anything, so they will re-check tomorrow using a computer.. When i mentioned the fuse box getting wet, the guy said it could never be the fuse box and that the mechanic would definitely have checked it.

I don't know why but i have this feeling they want to make a fuss out of it. Moreover, the mechanic i deal with usually is on vacation.

The guy is a doosh.

It's a known issue with YOUR bike, enough to have Harley write a TSB.

You can take my word for it or pay the dealer.

This is why i am asking, because i don't want to pay for the dealer, specially that they charge too much. Moreover, it's the 3rd day today and they can't identify my problem..

I think i will go pick my bike up from the dealer and handle it myself.

The first time my ignition relay went out I had to trailer it to HD shop and $112 later they replaced the relay, the second time the starter relay went I fixed it myself for less than $10 ! I liberally coated all fuses and relays with waterproof grease and haven`t had any problems since !
It might pay to have an extra relay with you, and if the ignition relay fails you can switch with the starter relay and give it a push to get started.

You can always pull another realy from something else and place it in it's place to see if that relay is bad.

Simple diagnostics.

Did anyone check the idle knob next to the hand throttle?

Well, Finally we discovered the problem.. Cost was around 195$. When the checked with the computer the errors, the crankshaft sensor and the air gate sensor were not working properly. Tried new ones but not working as well. Finally they discovered that the problem was in the throttle sensor. According to what the engineer from the workshop said, the O ring was not in a good state, this is why water came into the sensor.
