    Dumb question: starting bike without the gas tank on it.

    Again, I’m brand new to motorcycles. I’m finally at the place where I want to start the bike but I’m not able to. I have spark, decent compression and I’m feeding fuel directly through the fuel inlet on the left carb. As I pour fuel into a container that has a hose with the other end connected...

    New XS500 member, I hope you'll accept me. Starting frustration

    I know the xs500 is a bit of a downer in the XS line but I cant find a forum for them, so I hope youll accept me. I am working on a 76 XS500 cafe. I picked up the bike up for $100. After a lot of work I tested to see if it would run and I got it running enough to give me the confidence to keep...

    Won't start... Electrical issue?

    The bike was running just fine about 2 months ago. It would almost always start with little to no trouble and would run fine for the most part. After a series of projects that I've been working on I put everything back together and now I can't get ANYTHING. I'm getting absolutely nothing from...

    1982 XS400 Starts Sometimes, Not Others

    Hi guys, new member here, first bike I've ever owned. Bought this bike for $400 off craigslist about a month ago. It was running on one carb, so I took them out and gave them a thorough cleaning while replacing the float valves and needles. Put the carbs back in last week, fed them some gas...

    '78 Will Not Start With Choke

    Hello again! I have a 78 400E which is being a handful to say the least. Right now, the bike refuses to start with the choke on at all (or the enricher, whatever you want to call it) and requires a good amount of kicking and swearing before it fires up. Once started, if I attempt to put the...

    Xs360 won't start warm. Need help.

    I picked up my first bike a month or two back, it's an 77 xs360 and due to the time it took to get my license and what not I wasn't able to start riding until recently.
