1990 xt 600 won’t start
 

My bike sat outside covered for 2 months cause I was doing stuff in the garage. It was warm outside then started to get cold. Well took some time to get started but started I left the choke on for about 2 minutes then a little backfire then stalled. I tried starting but no good. It was my daily driver in NJ from March to November. Now I want to get her going now. Any suggestions. I do have a manual. The boots were changed a couple years ago and carb to were rebuilt. Also the bike ran good before it sat out side. Thanks for your help

Dont worry i will help you! First remove sparkplug and check for spark testing this. If you have spark next i will check carb, remove and clean up, take out filter inside and clean, blow air all passages in carb, check carb joints again, if its china aftermarked they crack after one year.

I used oem on everything for this bike cause I heard stories. Will start there

Ok. Starting to work on this. Checked plug well installed new and felt a spark on my hand so I know there is spark. Took air cleaner off and put starting fluid in the box so the fluid can get into carb. Try starting just cranked. Any help

Well hold on I felt the spark but I don’t see a spark on the spark plug and it’s new cofusing

Battery?
 

My '89 did not like it's 2 year-old battery. It would turn over and spark with the old battery, but not fire up and run. New battery = it started.

Just checked the coil ok resistance 5 ohms now checked the coil and plug wire to neg of coil nothing also took of spark plug adapter I have no ohms either can both be bad. any help thanks

Trying to locate both coil and spark plug adapter. Forget any thing coming from Japan at least 3 months. Also do you think I am right with the testing also do you know what would work like a cross reference. Thanks

Search ebay for spares, i dont know about your reading. Insert plug in cap and hold it against ground, turn engine look for spark. Ebay search: yamaha xt 600 ignition coil

I have a manual and used the ohm reading and only got reading on the primary on the secondary to the negative and the plug wire. Did try the plug to the head nothing Just orders a new coil and plug adapter for 113 dollars shipping too. They had It in stock. Am I doing something wrong. Thanks

Always good to have on extra even if its not the problem, old bikes and electric components dont last forever, good luck!

Now I ohm it out and now it’s good getting puzzled now tried the spark plug no spark at the plug but I get wrapped. Any possibility that something is grounding out

I am getting fuel from the tank to the carbs. The bike sat for 2 months outside with a cover on it and tender on it. Took a bit to start but started then ran for about 2 minutes on choke then stalled tried to start and then she just cranked and that is it. Getting frustrated

If I do have Spark is there any way to see if gas is getting into carb to fire up

From the left side you should see a drain screw under the float bowl. See what comes out of there .
