Thank you good sir. I started drilling last night and found that there was no space between the blind plug and the screw and did get into the screw so I need an easy out kit for that. I did a thread or two but they didnt seem to clear about what exactly needed to be done. Your explanation was...

I know this thread is old but did you ever find a solution to this problem? I think I have the same issue

ing have an 81 xs400h and I found an oil leak. I was trying get to get the bikes idle adjusted do that I could do a dynamic adjustment of the carbs and the bike started to smoke. Upon looking I saw oil leaking under the bike. I cleaned everything off and started the bike again and started...

OK thanks I'll look into it

What exactly do you mean adjust it the bottom end? I've never done this haha. I have a Haynes manual but I find it confusing most of the time

I was able to ride my 81 xs400h the other day. The issue I had that has been stumping me is this. When my bike is on the center stand and shift the bike into first while the bike is running it shifts into first no problem. When I get the bike off the center and shift into first while the bike...

Cool thank you

Is this the same screw that adjusts the single carb? That’s attached to the the arm that the throttle screw controls?

where are the screws to adjust the carbs when using a manometer? Trying to get this done haha and get this bike back on the road. Have a good one and ride safe

Awesome. Thank you both so much. If either of you live in the bay area of California I owe you a beer. I will be doing the bench sync today. I have to order the tach cable but found a place that has it for a decent price. Slowly but surely this will come together

The screw is this picture that you can turn by hand, is that the throttle screw? If I'm barely getting the butterfly valve to open moving that do I need to adjust somewhere else, or do I need a new screw, or both. I know I turn the screw at the top of this picture to set the other valve to match...

Where is the idle screw at. I looked online and in the Haynes manual and couldn't seem to find anything. I'll try doing that today. It's always fun trying something new and hoping it's right haha. Any guage wire you suggest to get me started? And should both butterfly valves be open the same...

So I probably need my tachometer hooked up to do a sync then? I went to install it but where it connects to the motor is broken so I need to find a used part. Unless I can just stick it on for the test and hold it on place haha. If anyone has a line in a replacement part I'd appreciate that also

I'm assuming there's a pretty in depth walk through on this site somewhere. I'll go looking Thank you.

Yeah stock air boxes and exhaust. I have to see about building a manometer. That just balances the carbs right? I can say that but I have no idea what it actually means haha

1981 xs400h I have this bike finally starting and idling but when I go to give it gas it first coughs and then revs as you would expect or it coughs and then dies. My first impression says not enough fuel but it was doing that when I was getting to much fuel as well. Am I not understanding...

Well going back to when we bought the bike about a month ago it didn't run. Knowing a little bit I knew I needed to clean the carbs and after finding this website I found I needed to clean them a good 3 or 4 times. Knowing the bike sat for a while I drained the oil and found it to be whitish and...

Thanks to you all I got the bike started today and idling. So great to have that happening and to hear her purr

When I did mine with an electric start I didn't get a spark and I got a little zap at the starter button haha

I got all three. I got it started today with starter fluid but I need to give it gas to get it started. The issue I'm having now is having it idle instead of stealing when I don't have the throttle pulled. From what I've seen on here I think I know where the idle screw is so now it's time to...
