    Replacing 1981 XS400 Carbs

    As far as running without the air filter, no worries carb wise. They can adjust just fine for any increased air flow. We use to run without air filters with our carbureted VW 1200s. But the dirt coming in required new pistons and cylinders each year. So if you don't mind replacing motor parts...

    Spark plug Rich/Lean

    It is hard to try and read plugs after many miles and idling. They are close enough to not mess around much unless you know what you are doing. DO NOT make any big swings. KISS rule applies .

    Replacing 1981 XS400 Carbs

    LOL yeah when I do something I do something went from the 400 to the 1800,:yikes: I didn't want to make 3 steps in between. Kind of stupid, I dropped that thing a bunch of times because it is so massive. But the fun when you twist it at 50 to 100 is blast. My friend had a VTX and I couldn't...

    Replacing 1981 XS400 Carbs

    It is an SOHC, 3 valve per cyl. Twice the weight of the Yamaha with 4.5 times the displacement and 5 times the HP.

    I have a general question for everyone here.

    Look for some books, maybe at the Library or magazines. I went to school for Automotive Technical students then to 4 years for a BS in Automotive Engineering. So keep working on it. Find an old motor, a air cooled VW bug motor would be good and take it apart. They are very easy to work on...

    Ballistic Performance: EVO2 Performance Battery

    I posted elsewhere that I wanted a good battery. THIS looks like just what I had in mind. I found a guy on Ebay who is here in Michigan and have sent a email. I'll give a report when I know more. Thanks for the information. Larry

    Replacing 1981 XS400 Carbs

    As Lou wrote he is right about; SOHC vrs DOHC (duel overhead cams). So DOHC have one cam for the intake and one for the exhaust valves. We have one cam actuating both intake and exhaust valves.

    NEW guy

    Hi guys thanks for the input. I am not a neophyte when it comes to batteries, but ones this small seem to be a b### to find one that can really kick the motor over and last doing that for more than one summer. I have been using 2 different ones to jump start it, one a DIE HARD (never been...
