So, my petcock is leaking again on '81 special II. I rebuilt it last year, and after putting new orings, etc from a kit, it ended up being the spring, which isn't included. So I stretched it out by hand, but now it's leaking again, so I'm assuming it's the spring again. A quick google search...

easy questions for you guys--a friend was telling me motorcycles should move into 1st gear with no throttle if you are easy enough.. My xs400 will not do it, without stalling, my RPM's immediately start going down as I let the throttle out... So, does this depend on the bike, is he right, wrong...

Okay last year my petcock messed up and was leaking gas.. I fixed the petcock, replaced inline gas filter, and drained oil, replaced filter. I took her for a ride, and everything was perfect again, and it has sat until now. Today, I started her up for second this year, and the first ride. ...

First, I don't ride often, and didn't ride this year with some issues. Took care of it just now, and I guess from my battery not being on a tinder for most of the year, it's dead now, and by dead, I mean, it won't recharge. it'll charge it just for an hour, and show it's good, but but it's...

So, I topped off with gas and added some seafoam and ran it for a while the other day to winterize the bike... noticed a few days ago, my garage smelled like gas... go out today and noticed a puddle of gas underneath , I see it dripping gas from the hose between the carb and air filter, and from...

New problem with xs400 1981 special... bought it in spring, rode very little, but it has always started and ridden fine the small number of times I have rode it this year. Took it ought today for a 20 minute ride, and only thing I did after was adjust open the idle mix screw a little, because...

Looking for seat hook and torsion spring that fits '81 Special II... Thanks Steve

After noticing my garage floor gettings scratched up, I was wondering if anyone has found or used some sort of rubber boot or shoe on the kickstand? I've been using a board in the garage as much as possible, but it's just not that handy or convenient sometimes. Thanks Steve

Hi.. I have a 1981 special II, and after switching the handlebars to euro styles, I noticed my rpms were reading zero when throttling. investigating I found what is in the picture, and I assume this is a tachometer cable? I am not mechanical, and changing the handlebars were challenging...

Hi.. new to the forum and to bikes in general. I am doing some minor things to the xs400 special II i got, and while cleaning the chain to later lubricate it, I was checking the tension. half of the lower chain is about 3/4 (good) slack, but when I rotated the back tire, the other lower half...

just got a 1981 xs400 special II, and the seat isn't locking... finally figured out that the rod, seat hook, and spring(s) that are suppose to be under the seat aren't there. i have to the two metal tabs (brackets) with the two holes, but everything else under the seat is missing.... anybody...

Looking over my xs400, i found this line with two clips on it... it's slightly leaking what I believe is fuel at the top portion, i assume the crimp isn't a big deal either? What is this line, purpose, and is a slight leak from the top a big deal? hopefully, the pic shows up, I'm new..the pic...

very simple question, but as I am a new motorcycle and xs400 owner, I need help. Just curious as the proper way to start from cold start, when xs400 won't start from just hitting start and giving it some throttle. Turn it to prime? choke position? what order...? I would just like an order to...
