i had a problem just like that kinda . my bike was runing tip top so i set out for along ride. i stoped for gas and guess what click click click for the solenoid . what i found to be the problem was the ground wire from the batt . i cut it and i found the inside was all green even tho the outside looked fine . lucky me i had enuff wire left to make a temp ground to get home . then i also realized that for week's it would run real rough till warmed up and would cut out and backfire then stall out for the 1st few min's of riding.i thought i still needed some more carb tuning. i have now replaced the ground and it run's alot better . no more problem's at all

ive spent 3 month's and 1700 miles geting this bike sorted out. alot of custom work has bin done and a few well wtf why not's . just installed was EBC clutch pad's, new EBC spring's, EBC front and rear brake pad's, and a new EBC front rotor. new turn signal's and new handle bars . i also lost a few lbs here and there . i finaly got the carb's dialed in with the new custom made exhuast baffle's . 1 more day of tuning and then i hit hwy 101 from here in san diego to as far up as i can go in 3 day's . here's some pics of her : the day i got her she look'd like this

thank's for the help guy's . as soon as the new pad's show up im going to bolt her up

i just got my replacement rotor from ebc . wow what a nice rotor . here's the thing: it's got counter sunk mounting hole's on the face so how do you mount it ? i understand i can use bolt's with holes for safety wire to mount it insted of locking tab's but what do i use in the countersunk hole's spacer's or washer's ? ive checked and it is the replacement rotor for my bike i just dont understand the hole's ? link: http://www.perfectbrakes.com/products.asp?cat=8012&pg=1

i made some change's to the front end . new bar's and new turn signal's and got rid of some weight . after the new pipes and pod fiters and new jet's and custom tuned baffel's this girl now run's strong . when i got the bike it was lower'd by 3/8 " i now raised it 1/2" and changed the bar's . here's some pics

sweet looking seca

here's the post i saw with info about that in drewpy's tracker project http://www.yamahaclub.com/forums/index.php...art=#entry96480

i got the jet's changed out today also put on some pod's . cuting out the air box was a big pain . i made a new box for the battery out of sheet metal . since ive done the pipes and even after the jet change i still have some bogging in the low rpm's . in 1st gear @ a stop when i take off it feel's like it lag's a bit then pick's up halfway thru 1st and then it's fine i went one size up from stock on the main's 117-120 RH / 127.5-130 LH the pilot jet's where already up alot past stock . they where like that when i got the bike. stock is 35 and thet both had 42.5. my mixture screw's are out about 3 1/4 turn's and they are new got them when i rebuilt the carb's afew month's ago . here's a vid of her with with the new change's enjoy here's some pic's too

do you have the pinkslip? or just a bill of sale ? if you have the pink and it's singed over to you . then just go to the dmv and do the title transfer . i do not belive they have to "see" the bike . aleast they did not need to see mine when i did my transfer 2 month's ago . good thing to cus mine was a big time mess . yes you will have to pay late fee's if you let it go for to long dont for get you will need proof of insurance to get the reg

here's a like i found for the tool http://www.z1enterprises.com/detail.aspx?ID=1698 . it;s for the xs650 but it look's just like the one for the xs400 dohc . for 12 buck's it's worth a try . i also plan on replacing the vavle shim's on my 82 xs400 seca . once you have the right shim's it look's like a very easy job to do . here's a link to the valve shim's they are down in the engine section http://shop.wemoto.com/index.dyn?oid=2147871

so i got some time to work on the pipes this weekend .i was going to get the mac 2 in to 1 but i just went ahead and cut up the old one's and welded some new pipe on then wraped them up . i cut out both xover's so now they are just straight pipes . the old pipes were double wall so i had to weld a bead around the inside where i cut them so they would not rattle around . they sound sooo loud i may baffle them . my new jet's and pod's from mikes xs will be here on monday then the tuning fun begin's . here's some pic's and a video enjoy

here ya go part #11 under fuel/air intake part's http://www.bikebandit.com/houseofmotorcycl...0g-1980/o/m8256

if your going all out cafe . i would also get yourself some rear set's . i my self am going to use these http://tcbroschoppers.com/id16.html . or these from RAASK http://www.raask.se/fy11.jpg and here's a dude who make's some nice tank's and seat's http://www.thetankshop.com/

here's a link for the cam's . i found on here . the xs400 is at the bottom of the list . http://www.megacyclecams.com/catalog/page57.pdf

i would if i was going to use the stock air box . i'm switching to pod's as soon as all my part's show up for the carb's .next the tail and seat are going bye bye .

some new pic's after a little paint . i'm still having a problem with the carb's . went it's hot out they hang around 3k-4k rpm often but not all the time BUT when it's cold out i can ride almost all day and they hardly do it @ all .i've looked every where for a vacum leak . i order'd some new carb holder's and some new jet size's i'm gonig to switch to pod filter's soon .i also finaly found the tool needed to change the vavle shim's . edit: the last 2 vid's were horrible here's some better pic's enjoy

i did a front shock oil change today . there was only about 1/2 a cup or less in them and it was black an nasty .very easy to do as long as you got a buddy to compress the top cap while you get that sob c-clip out . i went with 7wt feel's alot better. i can now "feel" the road . i'm still waiting for my EBC brake rotor and pad's to show up along with all new cable's and ss brake line's . the carb's are still a bit snotty

i got her for 500 buck's . i realy am starting to love this bike .

i used the magura front master cylinder - 16mm from mike'XS for my 82 xs400 seca and it work's better than the old leaky stock one

i cut the pipes @ the weld just after the foot peg's . you could cut them about 3" longer before you hit the baffles .i did this mostly becuse the baffles where cloged up bad and cuz i like loud bikes . i'm going to get the mac 2 in to 1 pipe set and fab my own "muffler" in a few week's . as for noise it's realy loud and would never pass a noise polution test .i would do the inspection then cut them .it may not be wise to run like this for a long time with the decreased backpressure im not shure . post up some pic's of your's i would love to see it

i found some time to toy with mona today . i cut the pipes down a bit . wow what a big diferance alot better throttle response and it was Loud just the way i like it. i'm still having some prob's with the idle hanging random kinda now mostly only when i get on the throttle hard . here's some new pic's enjoy stock: cut RH side: cut LH side:

i just finish'd replacing the master cylinder with the 16mm magura from mike's xs . look's real nice and work's better than the old leaky one . i'm going to go on a good long ride tomorrow and she how she hold's up

thank's drewpy . it's been 10 year's since i've had my hand's on a bike. this one was a real mess . it had alot of problem's . ran like crap the idle screw was missing it was just using the throtle cable adjuster to get idle . had a bad exhaust leak i was afraid that side was toast . but as luck would have it it's ok . the light's and key switch were a mess of cut up wire's stuffed behind the headlight . i had to redo all of it lot's of solder and heatshrink tubing . master cylinder had no screw's it was "glue'd "on and leaking badly . the whole front aftermarket faring and headlamp where held up with coathanger wire . i could not belive someone owned this raty snotty mess of a bike . all of this and more have been fixed the right way . i've bin lucky so far . the carb's still need some work pod fiter's are a must i hate that air box btw anyone know where i can get the valve shim's and the tappet locking tool . a good vavle adjustment will realy help me get this 400 in tune dtmf

here's my new to me 82 xs400 seca . it hardly ran when i got her. ive tore thru the motor and carb's like a mad man. thank's to info ive found here she now purrs like a kitten and makes good power . up next is new brake's rear shock clutch rebuild and mabe some new pipe's btw i got rid of those ugly mirror's and got some bar end mirror's
