Well bought a spark plug tester And there was a light on the tester all good there. Well maybe it’s time to take the carbs off. Anything else with electric thatvI should check. Possible grounding?

So I guess will pull off carbs now

Xt thanks for the info on carb all worked out Took carb apart and there was some gas in the carb. But I started to blow into the tube where gas goes in carb might I say might of been a blockage Can I use carb cleaner on the passages if so the orings will they be ok. I want to only do so much cause the parts are tuff being of the shipments. I can order later and redue again. Also float bo was clean and the screen had maybe a little but I am surprised no dirt in the bowl. Any other suggestions please send. Thanks again

No problem using carb cleaner, remove small filter under valve, screw holdin in place, when having open the bowl. Be careful wigling this out, its not the strongest metal brass. Remove pin first holding needle for open close petrol supply, hanging from float device, then remove brass filter, maybe wanna order new to replace with needle. Be real careful prising pin out so you dont break the pin holding legs! If you do its trash..Search Walmart. Com you find rebuilt kit motorgenic carb Yamaha xt 600

Yes sir took it all out all good. Where the screen was there was some debris there but looked okay. Cleaned out tube where fuel goes cleaned might of been blocked cannot say for sur but gave it all a good over. Cleaned out jets and those little passages.

Did you check that the engine kill switch isn't faulty? Ignition switch?

Does the bike have a full petcock / tap as standard or an aftermarket one? They can gunk up, as can aftermarket online fuel filters.

Is your problem two fold, no spark and no fuel, or just one?

Great, read this Thread, maybe same problem
Engine cuts out

Rock, I did read that article however so what your saying if the neutral switch is bad it would not start however mine is turning over. I thought that these safety switches are part of the ignition switch so they all have be closed to start or I should say turn over the motor as the push button is pressed Now if it’s cutting out I can understand there being a problem with one of the safety. But I will look into the switch for corrision because that will give me a voltage drop. I am going to check an clean all too

Just saying go over and check all components if you are missing power to coil, as the other thread we are on the transmitter for timing, just measure all so you know all are ok. Its the only way findding problems, good trick pass out all safety when its not turning. For now, get all togheter and try start up.

Neutral switch was the problem

Installed carb checked connection still cranks over but not even a back fire. I jumped out the relay for starter same.

Having a hard time checking valves. I see the rocker arm going up and down. Trying to get that feeler gauge in there. Now checked the manual I see as I turn the bolt counter clockwise 1-1 then 1, I line up that notch on the 1 correct there is no t on my flywheel correct. Thanks I think I’m giving up for tonight cleaning up

I did look at the video for the adjustment , maybe it’s that cdi box. The bike was running and stalled and then it doesn’t start back fire like it ran out of gas and that’s it. Now the neutral safety switch if that was bad it would not turn over correct. Thanks for all the help.

Valves dont go out of adjustment over night, they start making noise or go quiet if out of spec. Read thread Stillben xt600e no start, we been trough everything, start checking pickup coil.

Thanks Rock for not bailing out on me. I am going to take carbs out again and did not realize that the secondary carb has a main jet. Maybe that will help. But before all that I will keep cranking to see if there is fuel at spark plug when I take it out. The pick up coil ohm good. If I turn the ignition on I should get 12 v correct. The primary coil ohm good, the spark plug adapter ohm out good, the stator ohm out good even nothing to ground shorted. I did get wrapped from the spark plug wire when I was holding the spark plug against the motor with a set of pliers. But spark is hard to get against the motor. The battery is load test full chart and new but again it started then died. Do you know if there is anyway to to check to see if the tci is good. I don’t even see how to open it.
