I have a 01 yzf600r and durring a ride the engine will loose spark and will cut off if i let it sit for a while it will start back up but the relay assembly 4tv-81950-00-00 starts clicking

SOURCE: Yzf600r won't start. It produces a whining sound.

1) remove the starter give it twelve volts. If the bendix gear is engaging check for broken teeth on flywheel. If it is not engaging replace starter.
2) if starter and flywheel are ok the timing chain is probally broken.

i had a simuler problem with my honda cr 250 moto-x bike it would start fine and you could keep it ticking over with the throttle(i have deliberatly unscrewed the tickover in case i come off,it will cut out) when i got on it,it would go for about 400-500 metres then splutter and die and not start again for around 5 mins. i immediatly knew it was a fueling problem. so after stripping the carb and giving it a good clean out i was baffled when i got back on and it still done the same. i then dismantled the fuel tap cleaned it all out and put it back together and tested it,it was very very slow so i unsrewed my fuel cap a little and was greated with the familur gush it should deliver. problem solved! the vent in my fuel cap had crystalised up,so the fuel was coming out but the air was not getting in,causing a vacuum and slowing down the flow and basically emptying the carb quicker than it can fill back up!!! clean your carb,fuel tap and any vents in your cap or tank. if this does not work then your bike must be over fueling or low on compression.

SOURCE: Hello, My Yamaha YZF600 motorcycle wont start.

Hi there jfdnet! Yeah if you hear the relay operating and the starter is getting no juies then you need to replace the realy. First i would check you see if you get power to the starter. Use a light tester to check the hot wire on the starter and if you do have power the starter is bad. If you have power going to the relay but not going to the starter then the relay needs to be replaced. It is always good to use a light tester of multimeter to back track from the problem to find the source. Example: You turn the ign. switch but the starter wont turn, start with the tester at the stater them back track up to the ign. switch. Eventually you will find where the power hits a "brick wall" of a faulty part. I hope that this helps you out. Post any more questions you may have.
