It must be the new math, I am up to 10 on the profile content count, and I count 12 for posts or reply's.  Ajmboy what am I missing in order to get to 10?

robdoyle,  Thanks for the link!  This should be my 10th action, so I should be able to download it after sending!  Take Care!  billyz57

I'll get an in line spark tester tomorrow, and see what the Yamaha does, and let you know.  The other links that were posted talk having a bad pickup coil on the stator, and talk to how you can ohm it to verify.  Where do I test the stator at?  Again Thanks for your Help!!

You're welcome!

Well, since it restarts so reliably, that suggests that the battery and starter connections are ok.

But the cold start issue remains.  You have to use the pull start when the engine is cold (and only with the OE starter in place), and then the starter works when the engine is warm.

You're not the only Yamaha owner with this problem.  I found these similar threads: https://www.bluetraxx.com/threads/2000-warrior-pull-starts-it-runs-starter-wont-run.81426/ and https://www.bluetraxx.com/threads/2004-yamaha-warrior-350-wont-start-with-electric-button-but-starts-with-push-pull.82708/

Basically they are also suspecting that the spark is weak and testing the stator.  If you have a voltmeter you could try those tests on your stator.

However, it might not be so bad to live with it like it is, since you are able to get it running when you want.

Let us know whatever you decide to do

You can get an in line spark tester that will tell you if you're getting spark when cranking over.

Here is one carried by Harbor Freight https://www.harborfreight.com/in-line-spark-checker-63590.html

There are several others at various price points available mail order or in store at most auto and RV parts stores.

Here are the pictures.

Looks very similar to the Moto 4 350 I have. The Hi Low Reverse lever appears to be missing from the left side picture.

robdoyle,  Thanks for the reply!  Starter has been off.  I don't see any corrosion any where.  I did try to jump the old starter direct with jumper cables when it was off the quad, and it acted like it had a flat spot, e.g. ground the case and momentarily touch the POS jumper cable to the lug, and sometimes it would just spark, and some times it would spin.  So I ordered a aftermarket Chinese repop, and it arrived today.   Installed it and same condition, starter turns the engine over, but no start when cold.  OK, I'll see if it still starts on pull rope.  Nope!  The repop starter case that goes into the engine case is ~ 1/16 to 3/32 inch longer, and somehow the compression release does not release with the repop starter installed.  OK remove repop, reinstall old starter, same cold no start condition when old starter does turn engine over, Note I did get one backfire, but still no start cold.  Thankfully pull rope engages and starts engine.  I ride it up and down the driveway to warm it up, and then shut it off and try to start it on starter, and it starts 5 times in a row with no issues.  I didn't think to keep trying more times to see if it wouldn't start. I'm open to any and all suggestions??  Thanks in Advance!!

DavefromBC:  battery brand new and @ 12.75 VDC.  I'll check all the connections and Sparkplug, though.  Thanks for the advice!!

DavefromBC,  Sorry I should have been more specific.  Starter engages, engine turns over, but won't start most of the time.  After I can get it started by pulling rope and it has warmed up, sometimes I can shut it off and get it to start with the starter, but most of the time it just cranks and no start.  Thanks for the Reply!!

I have a YFM 200 complete, but no compression.

New to Quadcrazy, Has any Yamaha owners had similar issue?

1987 Yamaha YFM 350 Starts on Pull, but just spins on starter, and won't start.

I had the same problem on a 87 YFM350, and mine ha the compression release lever. I still have to try several times before the pull rope catches when it is fully retracted in the case.
