Engine starts when ignition swiched on - YZF 600 R thunder cat Yamaha Motorcycles

You have a ignition swiche problem, replace and or inspect

Replace ignition swich

It is designed that way. Based on my experience you have a defective ignition starter swich, it is a common fault and the subject of many recalls for this very problem. The switch is at the botton top of the steering column

Yes it could be the switch.
Or something in the engine compartment.

it thinks your are trying to steal it. are you using the correct key? so you need a dealer or a shop to check it out.

clicking when you turn the ignition on most vehicles could be one of two things. First the selenoid for the starter. Second the batterry is worn out or drained. Since your jeep starts with the remote its not your battery. Lucky for you your remote starter is like having a second selenoid. If you are so inclined you might try to fix it yourself. Open the hood. Have someone else turn the key. Follow the sound. I don't have a jeep of that model to look at but It could possibly be comming from a two post terminal that is realatively easy to change. If you are worried about reassembly take pictures before you start. Clean all connections that look corroded.

souns like the electrical part of the ignition swich is worn out. replace this swich under the ignitionkey and will be as before. good luck

Bad ignition switch in column. Bad key switch.

check your reverse swich. if the switch doesnt see connection, being out of reverse/in reverse, then the ignition switch will not get supply power. look for swiches/sensors by the shifter and ignition swich for possible faulty switch/sensor. hope this helps
