Weak battery. We all use AGM batteries as standard wet cells don't work well on this bike.

The clicking means a dead battery or loose battery/starter connection somewhere. Combined with slow cranking beforehand, I'd say dead battery.

even hooked up to a running car battery it didn't turn over, it took forever to slow start, and it was extremely slow cranking over, then cranks over, now its a fast start but goes straight to clicks. battery is ruled out

Not sure I could rule out the battery yet. Sounds like it got a charge and maybe cranked better? Needs checked with a volt meter and all the connections checked. A weak, freshly charged battery could do exactly as you described.

It shouldn't be jumped from a running car, that can cook the rectifier on the bike.

just for the sake of argument, rule out the battery. it was brand new. not battery, what causes the clicking sound? again its not the battery!! i say again, it was a slow crank, and i know u wanna say battery cause it was slow, but isnt the starter/or solenoid the one thats suppose to do the cranking?

The clicking comes from the solenoid operating on low current. The relay contacts close when current is first applied (click), weak current can't hold the contacts closed so they open again (click). If the start button is held, the clicking continues until there's no current left.

Either from a weak/dead battery, or a loose connection.

Good luck!

edit: The starter does the cranking, but it takes amps from the battery to make that happen. Low amps = slow cranking. In the case of a worn out starter, the starter pulls more amps than even a fresh battery can supply.

I wouldn't suggest a new starter until the battery is load tested.

Oh TeamGreen, the contactor or solenoid on these bikes seems to drop out around 11.5 volts. So it has to have a really good battery and voltage supply.

That being said, I did jump mine off numerous times with my truck and didn't know it could damage the RR. It cranked fine like that with a known bad battery. So I'm not sure it's your battery, but could be a bad starter or bad connection.

ALSO, if your carb is flooding or your tank petcock valve is bad, it could flood your front cylinder and act like a weak battery / bad starter / bad connection etc... because the front cylinder is attempting to compress liquid. Ask me how I know...
