engine wont start

[Jimbo31]

I would just like to say that I read before about switching the coils but I couldnt quite understand why that would make a difference because I was lead to believe they were exactly the same. HOWEVER I just switched them like everyone suggested and it started right up, it runs perfectly im very VERY happy.

thanks everyone so much for helping out Im very grateful. I will be posting my build on here once my semesters over and hopefully the bike will be finished.

thanks again!

I'm glad is was an easy fix!

jimbo I can tell you exactly how you did this. You probably labeled the wires when you too them off right? Left, right, etc.

Then you reinstalled your coils backwards but followed the labels you put on your leads. By your labels youd think you were correct. problem being the COILS were backwards and firing at the wrong time. Like I said.

We've ALL done it once!

XS LEO, that is a cool fact I didn't know Seems like he had his front end back on before this was an issue, but it's a cool thing to find out.

Hello all, I'm just about to get an XS400 but it doesn't start, any knowledge you can pass down to a newbie?

New gas, spark plugs, test wet and dry compression, then, virtually inevitably, carb cleaning.

As @Lou Ranger pointed out, all roads lead to the carbs. Clean them even if that is not the initial issue.
