    New jets, new problems

    Hey guys, had my bike running good last year, was running a tiny bit lean in the mid range, and rich in idle and low (father drilled out pilot jet too big after a tune), now I installed jets one size up (145 mains and 45 pilots now) from factory to accommodate my MAC exhaust, and it idles high...

So I was looking at new petcocks, alot...

    Why has Sheniqua turned into a bear?

    Hi. If you've been following me for a while now, you'll know that my 81 xs400 special in all black is Sheniqua. And lately she has been living up to her name more than normal, one hard to start black b****..... The year prior to this, if i went and started her the night before i would go on a...

    Sheniqua is back!

    Drewpy youll be happy to hear this. After a friend of mine rebuilt her carbs and I installed a fresh set of filters all around, also replacing the broken turn signal and headlight, Sheniqua fired right up today, no choke, no starting fluid. I am also happy to report that she has a bit more pep...

    Sheniqua after the year

    Well, 2012 was good for me and Sheniqua. we rode just about every weekend when class and weather permitted. No real issues after a complete rewire. However, in my usual fashion, and I hope this isnt customary, the very last day of riding season I leave work early to go for a ride. I pop the...

    Standard carb settings

    OK, so lets pretend that Sheniqua isn't a stubborn b**** to get started after not riding for more than 3 days, what are the standard settings for stock exhaust with regards to the main and pilot jets, and possibly the idle screws. Ok, so any setting I can adjust on the carbs aside from F/A...

    Sheniqua is finished

    Yep. Got most of the mechanical issues worked out and then sent her up north for my father to do a rewire over the course of a month or so. She needs a new seat upholstered though, after about an hour of riding it's hard to even remove myself from the bike :( But I am happy she is home and...

    Need to rebuild petcock?

    I removed my fuel tank, and when I tested the petcock on it it seemed to work just fine. Came back to storage a week later and there was a small puddle underneath the petcock, when I left it there in the OFF position. When I hold the tank up, ON and OFF, i t doesn't let any fuel pass, but when I...

    Starting my project

    At the suggestion of Daddio, going big, were thinking that a tracker may be in the future. But am I correct in saying my first step is a complete teardown and cleaning? I can take all the parts to work for sandblasting or grinding and paint them again. If yes, then I start tomorrow. But if I did...

    Tipping danger?

    I'm about to take the wheels off my bike to put some new tires on there. I'm going to put the bike on a concrete block below the engine and frame to support it, is there any reason that the bike would tip off of there after removing both the wheels? Need to make sure she isn't going to fall over...

    Shaving weight

    Are there any easy ways to drop weight on my 81 special? I've already removed the front wheel fender, the side covers and the passenger footpegs. Are there any other easy things to do to drop weight? And does it really make a difference in power? I was considering doing away with the electric...

    Neutral isnt there anymore

    Just got my bike, 81 xs400 special. Doesn't seem to want to go into neutral. Also tried a kickstart and that wont work because theres no neutral. The electric start is just fine but id like to have neutral. Seems to shift alright on the road too.

    Syncing carbs without vacuum gauge?

    How can it be done? I was reading on how to do this but I do not own a vacuum gauge set. Was wondering if you all had a way of verifying carb sync without using these. Thanks

    Picking up bike today

    I'm picking up my 1981 XS400 today, and the dealer said they drained the oil because it had gas in it. Am I going to need to rebuild/complete clean the carbs or just clean? And I have no choice but to ride it once to my shop where I can start working on it, will I need to change the oil again...

    Stock or Straight?

    So reading around, I see that my xs400 would be very loud if I went with a straight exhaust on it. And honestly, I would love to have a loud bike, but would it be too loud at that point to where I wouldn't want to take it on long rides? Or would I just have to go the earplugs route? I might even...

    Hello

    Hi everyone, my name is Wes, and today I have just bought a 1981 Yamaha XS400 Special with 3,600 miles on it. I have riding experience on 1980's Suzuki GS300 and a Hondamatic 400, but this is the first bike that I actually own. I have a shop to keep it at, but was wondering what tools are...
