Its a 1980 xs400 SE. I no, I measured nothing, what I am now kicking myself for because these hours of trial and error are definitely not worth it. Plugs were very old so I changed them, brownish and crusty.

I came here for help a little while ago, did some homework, started tinkering, and now I can't seem to maintain an idle on my xs400. I'm thinking my fuel mixture is way off but I can't for the life of me get it set right. When i initially opened up the carbs I noticed the floats were set way...

I too would like to learn more about this. Sounds almost exactly like what happened to mine. Ran fine while my turn signals weren't working, but soon as I fixed them the diving idle started again. At first i thought they weren't related but this seems like too much to be a coincidence...

Thanks! I have the manual and a voltmeter, Time to start experimenting!

And forget about using the electric start! Unless I've used the bike within the last hour its useless!

I got my 80 xs400 About a year ago. Got the carbs cleaned at a Yamaha garage immediately and it has been running great, until recently. The bike has always been hard to start up when its been sitting for more than a few hours. It usually takes me 5-10 kicks on a warm day, 10-20 in the fall...
