no start

So I had the bike out n about earlier this afternoon and it ran great and all felt good. I went to start it after it cooled off substantially I'm guessing the oil thickened and is causing it to not start. But after cranking it over for 20 minutes it spit and sputtered back to life momentarily...

Hello I am having an issue with my 1983 XS400R Seca. I road in the morning, the day after my bike had been in the rain, to work with no issue. When I was about to head home, I tried to start it and it turned over fine but wouldn't go/catch at all, just endlessly turn over. Figured out there was...

I posted about this earlier but I bough a project 79’ 400 that had a screw embedded in the head. I did a top end with a new head and that went fine. Compression went from 90L, 120R to 150 L and R. I went through some issues with the carb but it has been cleaned with a full rebuild (compressed...

I fried my ignition coils, replaced them and now won't start. Also found white wires from stator melted together. Cut out bad wires and spliced together. When I run my key on and kill switch on to start the bike I have a massive voltage drop at battery. From 12.8v to 8v almost instantly. Turn...

Hey guys, having issues with my 1982 Yamaha XS400, I believe it is a Maxim. When I first got her she wasn't running and was making a clicking noise when I tried to start it. Found the ignition fuse loose and she was up and running. It's been about 4 months, I've made a couple of upgrades but...

Hi Everyone, I'm new to this site (actually to the whole "forum" thing entirely!) but I've been having trouble with my bike and would gladly take all the help I can get! So a little history: In a previous buy I got two yamaha xs400's (1977 and 1978 I think). The 77 had a title so I used that...

Hi all I've got an 82 XS400 Special-II that won't start. The electric starter has always been dodgy and worked only if the bike was warm or on a booster. The kick start worked on the first or second kick for the first 5 years I had the bike. Now I've got nothing. Just came out one day and it...

Inherited a 1981 XS400. No carbs but seemed otherwise complete. I kicked it over and you could hear and feel compression. Got a good set of carbs and bolted them on today. Changed spark plugs, put in fresh oil, added an inline fuel filter, added gas, and tried to kick it over. Nada! - When I...
